Updated September 2026

WP Rocket's [own knowledge base](https://docs.wp-rocket.me/article/1711-what-happens-if-my-license-expires), fetched 25 September 2026, lists six things a site loses when the licence expires, and three of them keep working for another fifteen days before they stop. WP Fastest Cache's [premium page](https://www.wpfastestcache.com/), checked the same morning against a plugin last updated 13 September 2026, sells a one-time fee with unlimited updates and no renewal date at all. The comparison people expect is which of them makes a page load faster. The more useful comparison is what each contract leaves you holding on the day you stop paying, because that difference is documented, permanent and almost never priced into the decision.

This article reads both vendors' own pricing pages, licence documentation and plugin readme, all on 25 September 2026, and compares what each licence buys rather than what each plugin scores.

## Quick Summary: Which Licence Leaves You Holding More

| If you want… | Do this | Why |
|:---|:---|:---|
| To pay once and never see an invoice again | WP Fastest Cache Premium, $49 for one licence | The vendor's FAQ says plainly: "This is not yearly. Just you can pay one time and use forever" |
| The widest feature set applied automatically | WP Rocket, $59.95 a year | It applies most optimizations at page generation and ships the cloud features the free field does not have |
| To know exactly what breaks if you lapse | WP Rocket | It is the only one of the three that publishes a complete list, and the honesty is worth something |
| Page caching for nothing, forever | WP Fastest Cache free | It page-caches on any standard PHP host, with no upsell gate on the cache itself |
| JavaScript optimization without paying | Neither | Four of the five JavaScript features in WP Fastest Cache are premium, and WP Rocket has no free tier |
| A lifetime licence with an AI and MCP layer | xSpeed Cache Pro, $79 once for one site | Ours, and dearer than WP Fastest Cache at one site. The reasons to pick it anyway are below, along with the reasons not to |
| To move the licence to a new domain in year three | WP Rocket | WP Fastest Cache closes the transfer window twelve months after you assign it |

## Two Licences, Two Different Promises

WP Rocket sells an annual subscription. [The pricing page](https://wp-rocket.me/pricing/), read on 25 September 2026, lists Single at $59.95 a year for one site, Plus at $119.95 for three, and Multi at $299.95 for fifty, with options for one hundred and five hundred above it. There is no free version and no trial. The page says so directly: "We don't offer a trial version, but we do have a 14 day refund policy, so you can buy with confidence." Renewal is automatic by default and can be turned off in the account billing section.

WP Fastest Cache sells two things. There is a free plugin in the WordPress directory, which a query to the [wordpress.org Plugin API](https://wordpress.org/plugins/wp-fastest-cache/) on 25 September 2026 returned as version 1.5.2 with 1,000,000+ active installs and a 4.9-star average from 4,225 ratings, last updated on 13 September 2026. And there is a premium licence bought as a one-time fee: Bronze at $49 for one licence, Silver at $125 for three, Gold at $175 for five, Platinum at $300 for ten. Every tier on that page carries the same four lines under the price: One-Time Fee, unlimited Support and Updates, 10,000 Image Credits per License, and a one-year licence transfer right.

Those two shapes produce different questions. An annual licence asks what happens when you stop renewing. A one-time licence asks what the vendor is still obliged to give you in year five, and what it quietly meters in the meantime. Both questions have documented answers, and neither is the answer a benchmark gives you.

- **An annual licence is a rental with a service attached.** Part of what you pay for runs on the vendor's own hardware, and that part can be switched off independently of the code sitting on your server.
- **A one-time licence is a purchase with a meter attached.** Nothing expires, but the pieces that cost the vendor money every time they run are counted out in advance, and the right to move the licence somewhere else carries a deadline.

One number does not exist for this comparison and it is worth saying so rather than estimating. A direct query to the wordpress.org Plugin API for the slug `wp-rocket` on 25 September 2026 returned `Plugin not found`, because WP Rocket has never been distributed through the directory. There is no install count, no rating average and no version history to compare against WP Fastest Cache's million. Any figure you see claiming otherwise was inferred.

## Master Comparison: What Each Licence Actually Contains

| Dimension | WP Fastest Cache Premium | WP Rocket |
|:---|:---|:---|
| Payment shape | One-time fee | Annual subscription, auto-renewing |
| Entry price | $49, one licence | $59.95/yr, one site |
| Three sites | $125 once | $119.95/yr |
| Five sites | $175 once | No tier; nearest is $299.95/yr for fifty |
| Ten sites | $300 once | No tier; nearest is $299.95/yr for fifty |
| Free tier | Yes, page caching on any standard host | None |
| Updates after payment stops | Unlimited, per the vendor FAQ | Stop at expiry |
| Cloud-dependent features | Image optimization and WebP conversion | Remove Unused CSS, Load CSS Asynchronously, Rocket Insights |
| Metered element | 10,000 image credits per licence | None documented on the pricing page |
| Licence transfer | Within twelve months of assignment | Any time while the licence is active |
| Refund window | 30 days, via Paddle as merchant of record | 14 days |
| In the wordpress.org directory | Yes, 1,000,000+ installs | No, and no install figure exists |

Two rows in that table do most of the work, and they point in opposite directions. WP Fastest Cache never stops updating and never stops working, but it meters image processing and locks the licence to a URL after a year. WP Rocket meters nothing and moves freely between domains, but it takes six named things back when the invoice goes unpaid.

## The Lapse Test: Five Questions to Ask Before You Pay

Comparisons of caching plugins measure the day you install. Almost none of them measure the day you stop paying, which for an annual licence arrives on a schedule and for a one-time licence never arrives at all. The five questions below are answerable from any vendor's own documentation in about ten minutes, and the answers are more stable than a benchmark score.

1. **Does the page cache keep serving?** This is the floor. If the cache itself is licence-gated, everything else is academic.
2. **Do plugin updates continue?** Updates are how a plugin stays compatible with new WordPress and PHP releases. A plugin frozen at today's version is a security decision, not a performance one.
3. **Which features run on the vendor's servers?** Anything processed off your host is a service, and a service can be withdrawn independently of the code on disk.
4. **Can the licence move to a different domain, and for how long?** Sites get rebuilt, renamed and sold. A licence bound to a URL is worth less than one bound to you.
5. **Is anything metered, and what happens at zero?** A one-time fee with a consumable inside it is a subscription wearing different clothing.

Here is how the two products answer, quoting each vendor's own documentation.

| Question | WP Fastest Cache Premium | WP Rocket |
|:---|:---|:---|
| Page cache keeps serving | Yes, no expiry exists | Yes, "will continue to operate normally" |
| Updates continue | Yes, "you can update the premium version forever" | No, plugin updates stop at expiry |
| Server-side features | Image optimization, credit-metered | Three cloud features stop 15 days after expiry |
| Licence moves domain | Only within the first twelve months | Yes, by removing the domain from the account |
| Metered element | 10,000 image credits per licence | None documented |

![Side-by-side of what a WP Rocket licence and a WP Fastest Cache Premium licence stop providing when payment stops](https://xspeedcache.com/images/blog/licence-lapse-test-wp-rocket-wp-fastest-cache.webp)

WP Rocket's documentation is unusually specific, and it deserves quoting rather than paraphrasing. Its [article on licence expiry](https://docs.wp-rocket.me/article/1711-what-happens-if-my-license-expires) lists what you lose: support, plugin updates, updating of the dynamic exclusions and inclusions, the free plan of the RocketCDN add-on, and the cloud features, which it names as Remove Unused CSS, Load CSS Asynchronously and Rocket Insights, plus the pre-warmup process for the Priority Elements features, noting that those optimizations still run when a real visit triggers them. It then draws the line explicitly: "After the license expires, the WP Rocket will continue to operate normally, except for the cloud features that will stop working 15 days after license expiration." The reason given is a cost one, and it is a fair reason: "These features are run as an external service from servers that we have to maintain."

Read the pricing page afterwards and one sentence in the renewal FAQ reads differently. It says the licence renews automatically "so you don't lose access to some optimization features, support and updates". That phrase, "some optimization features", is the three cloud features above, and the documentation names them where the pricing page does not.

### What the test cannot tell you

Three limits, stated plainly, because a framework that hides them is worth less than no framework.

- **It reads documentation, not behaviour.** Every answer above came from a vendor page on 25 September 2026. Policies change, and a page can lag the product in either direction.
- **It says nothing about speed.** While both licences are paid and current, this test is silent on which plugin produces a faster page. That question needs a measurement protocol, not a contract.
- **It cannot price support.** Both products include support in the licence and neither publishes a response-time commitment, which is the same gap our [WP Rocket pricing breakdown](https://xspeedcache.com/blog/wp-rocket-pricing/) ran into when it tried to put support in a cell.

## The Free Tier Line, Counted From the Readme

WP Fastest Cache is one of nine free plugins that genuinely page-cache on an ordinary PHP host, which our [survey of free caching plugins](https://xspeedcache.com/blog/free-wordpress-caching-plugins/) established by reading each plugin's own readme rather than its feature grid. That makes the free tier a real product, not a demo. The interesting question is where its ceiling sits, and [the readme](https://plugins.svn.wordpress.org/wp-fastest-cache/trunk/readme.txt) answers it by listing both sides.

The free performance list has eight entries: page caching, minify HTML, minify CSS, gzip compression, browser caching, combine CSS, combine JS, and disable emoji. The premium list has thirteen: mobile cache, widget cache, minify HTML Plus, minify CSS Plus, minify JavaScript, combine JS Plus, defer JavaScript, optimize images, convert WebP, database cleanup, Google Fonts async, lazy load, and delay JS.

Group those thirteen by job and the line stops looking arbitrary.

| Job | In the free tier | Behind the fee |
|:---|:---|:---|
| Page caching | Page cache, preload, exclusions, CDN and Cloudflare integration, WP-CLI, Varnish purge | A separate mobile cache, widget cache |
| CSS | Minify CSS, combine CSS | Minify CSS Plus, Google Fonts async |
| JavaScript | Combine JS | Minify JS, combine JS Plus, defer JS, delay JS |
| Images | — | Optimize images, convert WebP, lazy load |
| Database | — | Database cleanup |

![Table of WP Fastest Cache features by job, showing which sit in the free tier and which are behind the one-time fee](https://xspeedcache.com/images/blog/wp-fastest-cache-free-premium-line.webp)

Four of the five JavaScript optimizations are premium. All three image optimizations are premium. Both of those are the categories that move a modern PageSpeed score most, which is a reasonable place for a vendor to draw a line and a useful thing for a buyer to see before installing. The readme is not coy about it either: "The free version is enough to speed up your site but in the premium version there are extra features."

One entry in the free caching list is easy to misread. The free tier includes an enable or disable switch for caching on mobile devices. That is not the same thing as the premium Mobile Cache, which stores a separate copy of each page for mobile visitors. The free switch decides whether mobile visitors get the desktop cache at all.

## What a Site Means Is Not the Same in Both Contracts

Both vendors sell licences counted in sites, and the two do not count the same way. This is the row most likely to change which product is cheaper for you, and it appears on no comparison chart.

WP Rocket's [documentation on licence counting](https://docs.wp-rocket.me/article/66-how-many-sites-is-my-key-valid-for) defines one site as one top-level domain. Its worked example lists `example.com`, `www.example.com`, `dev.example.com`, `demo.example.com` and `example.com/dev/` and states that all of them "are allowed to share the same WP Rocket license key" and count as one site, even though they are separate WordPress installations. Local domains are not counted at all. A Multisite network cannot be network-activated and has to be activated per sub-site, but because the network shares one top-level domain, the licence still covers it.

WP Fastest Cache assigns a premium licence to a URL. [The FAQ](https://www.wpfastestcache.com/faq/) is one line: "You can use the premium version just for one site." [The transfer page](https://www.wpfastestcache.com/transfer-license/) adds the constraint that matters most in year two: "The window for transferring your premium license remains open for 1 year, starting from the date when you assign the premium license to any URL. After the one-year period passes, the option for transfer will no longer be available."

![Comparison of how WP Rocket and WP Fastest Cache count one site across a live domain, a www host, a staging subdomain and a subdirectory install](https://xspeedcache.com/images/blog/one-site-licence-unit-mismatch.webp)

So a developer running a live site, a staging subdomain and a local copy needs one WP Rocket licence and, on the strictest reading, more than one WP Fastest Cache licence. A studio that rebuilds a client site on a new domain in year three can move a WP Rocket licence in three clicks and cannot move a WP Fastest Cache one at all. Neither of those is hidden. Both are one page away from the buy button, and almost nobody reads them before paying.

## The Arithmetic, and Why It Is Not the Whole Decision

Our [pricing breakdown of WP Rocket's ladder](https://xspeedcache.com/blog/wp-rocket-pricing/) already worked through the per-site total cost of ownership across this field, including the finding that there is nothing between the three-site Plus licence and the fifty-site Multi one. Rather than re-derive it, here is the narrow comparison this article adds, using list prices read on 25 September 2026 and no assumptions about discounts.

| Sites | WP Fastest Cache, once | WP Rocket, year 1 | WP Rocket, 3 years | WP Rocket, 5 years |
|:---|:---|:---|:---|:---|
| 1 | $49 | $59.95 | $179.85 | $299.75 |
| 3 | $125 | $119.95 | $359.85 | $599.75 |
| 5 | $175 | $299.95 | $899.85 | $1,499.75 |
| 10 | $300 | $299.95 | $899.85 | $1,499.75 |

At three sites WP Rocket is genuinely cheaper in year one, by $5.05, and that is the only cell in the table where the annual licence wins on price. At five sites the gap is the structural one: WP Fastest Cache has a five-licence tier and WP Rocket does not, so a five-site studio buys fifty seats it will not use. By year five the five-site row reads $175 against $1,499.75.

The ten-site row is the one worth pausing on. WP Fastest Cache's Platinum licence and WP Rocket's Multi licence are priced five cents apart in year one, at $300 against $299.95, and from year two they separate permanently, because one of them is finished and the other renews. Nothing about either product changed between the five-site row and the ten-site row. Only the shape of the ladder did.

That arithmetic is real and it is also incomplete, for a reason the lapse test makes visible. The $175 buys a plugin that keeps updating forever and four JavaScript optimizations WP Rocket applies without a thought. The $299.95 a year buys a wider automatic feature set, cloud processing for unused CSS, and a licence that follows you to whatever domain you are running next year. A price table that does not carry those rows is measuring the invoice rather than the purchase.

## Running This Where Nobody Is Watching the Renewal Date

The failure mode neither price table shows up in is an agency one. A licence bought for a client site in March expires the following March, on a card that belonged to a contractor, and nothing visible breaks. The page cache keeps serving. Fifteen days later the unused-CSS processing quietly stops, the CSS that was being loaded asynchronously goes back to blocking, and the site's Largest Contentful Paint drifts upward over the following weeks with no deploy to blame it on. WP Rocket's documentation predicts this precisely, and a monthly PageSpeed screenshot will not tell you it happened.

Two habits catch it, and neither needs a tool you do not already have.

- **Check the cache from outside the dashboard.** The admin screen reports what the plugin intends to do, not what the visitor received. Our [guide to confirming a cache is really working](https://xspeedcache.com/blog/check-wordpress-caching-working/) covers the response headers and page-source markers each major plugin leaves behind.
- **Keep a dated record of which optimizations were reaching the page at sign-off.** A screenshot of a score is not enough, because a score moves for a dozen reasons at once. A list of the markers actually present in the page source gives a later comparison something specific to check against.

This is the problem xSpeed Cache was built around, and we should disclose before describing it: xSpeed Cache is ours, built by WPDeveloper, which is a Startise company. The Pro tier sells both ways, $29 a year or $79 once for a single site, with lifetime tiers at $149 for five sites and $249 for twenty-five, all listed on [our pricing page](https://xspeedcache.com/pricing/). The lifetime option exists for exactly the agency case above, where the renewal date is the most fragile part of the arrangement. The free tier page-caches on any host and includes lazy load, minify and combine for CSS, JavaScript and HTML, object caching and scheduled database cleanup, which is a wider free line than WP Fastest Cache draws and a much wider one than WP Rocket draws, since WP Rocket has no free tier.

Two things run across a fleet rather than a site. xSpeed Hub gives one dashboard over every site you have connected, and the MCP server is in the free tier, so an agent can read cache state and change settings across the portfolio without one connection per site. Whether either matters depends entirely on whether you run one site or forty, and on a single site xSpeed Cache is one option among several rather than an obvious answer.

Run the free scan on your own site: [xspeedcache.com/scan/](https://xspeedcache.com/scan/)

Where xSpeed loses this comparison, and the numbers are today's: the wordpress.org Plugin API returned 7,000+ active installs for xSpeed Cache on 25 September 2026 against WP Fastest Cache's 1,000,000+, and WP Rocket has a decade of compatibility reports behind it that we do not. WP Fastest Cache's $49 one-time licence undercuts our $79 lifetime launch price at one site outright. And on the lapse test itself, our own pricing page says yearly plans "include a full year of updates and support" without publishing the itemised list of what stops afterwards that WP Rocket publishes. WP Rocket's documentation is better than ours on the exact question this article is about, and the honest thing to do is say so and fix it.

## Common Mistakes Buyers Make Reading These Two Price Pages

- **Comparing $49 to $59.95 and stopping.** They are prices for different things: one buys a plugin permanently and meters its image service, the other rents a plugin plus three cloud services annually.
- **Assuming a one-time fee means nothing is consumable.** Each WP Fastest Cache licence carries 10,000 image credits. The FAQ's answer to running out is "You can buy it easily", which is a repeat purchase by another name.
- **Counting staging and development sites the same way for both.** One WP Rocket licence covers every subdomain of a domain. WP Fastest Cache assigns a licence to a URL.
- **Treating an expired WP Rocket licence as harmless.** The plugin keeps working, which is precisely why the three cloud features stopping goes unnoticed.
- **Buying WP Fastest Cache Premium for JavaScript optimization without checking the free tier first.** The free tier already combines JavaScript. It is minify, defer and delay that are behind the fee, and it is worth confirming your theme needs them.
- **Running both at once during a trial.** WP Fastest Cache's own readme is blunt about this: "It is very inconvenient to use multiple caching plugins at the same time." Our [notes on migrating between cache plugins](https://xspeedcache.com/docs/migration/) cover the order to do it in.

## Frequently Asked Questions

### Can I use WP Fastest Cache Premium forever without paying again?

Yes, with one caveat. The vendor FAQ says the price "is not yearly" and that "you can update the premium version forever". The caveat is the 10,000 image credits included with each licence, which are consumable and repurchasable.

### I let my WP Rocket licence expire six months ago. Is my site slower now?

Probably, and in a specific way. Fifteen days after expiry, Remove Unused CSS, Load CSS Asynchronously and Rocket Insights stop. Page caching, minification, lazy loading and delay JavaScript are local and keep running. Compare the current page source against an archived copy from while the licence was active to see which of them left.

### My site has a staging subdomain. Do I need two licences?

For WP Rocket, no. Its documentation counts subdomains of one top-level domain as a single site. For WP Fastest Cache, the premium licence is assigned per URL and the FAQ limits it to one site, so budget accordingly.

### Should I buy WP Fastest Cache Premium if I only want faster JavaScript?

Check the free tier first. Combining JavaScript files is already free. Minify JS, combine JS Plus, defer JavaScript and delay JS are the four that are not, so the question is whether your theme benefits from those specifically.

### Is there a free option that does what WP Rocket does?

Not one plugin, no. WP Rocket has no free tier, and no free plugin in the directory matches its automatic unused-CSS removal. WP Fastest Cache's free tier covers page caching, CSS work and gzip, which is most of the load-time benefit for a simple site.

### Do I lose my settings if I switch between these two?

You lose them either way, because neither reads the other's configuration. Our [WP Rocket migration guide](https://xspeedcache.com/blog/migrate-from-wp-rocket/) explains why the order matters: WP Rocket stores its settings in one options row, and deleting the plugin before exporting destroys it.

### Can I move a WP Fastest Cache licence to a new domain?

Only within twelve months. [The transfer page](https://www.wpfastestcache.com/transfer-license/) states the window opens when you assign the licence to a URL and closes one year later, after which "the option for transfer will no longer be available".

### How many sites does WP Fastest Cache actually run on?

The wordpress.org Plugin API reported 1,000,000+ active installs for the free plugin on 25 September 2026. The vendor's own site claims 1,500,000+ websites. The first figure is a directory bucket and counts only the free plugin, so the two are not measuring the same thing.

### Does WP Rocket include a CDN?

A limited one. Its pricing page describes a free RocketCDN plan covering "3 key pages" across ten edge locations with no bandwidth limits. The free plan is among the things listed as lost when a licence expires.

### We run twenty-five client sites. Which of these is cheaper?

Neither tier fits cleanly. WP Fastest Cache stops at ten licences, so twenty-five sites means multiple packages. WP Rocket jumps from three sites to fifty at $299.95 a year. For a portfolio this size, compare all three products on the [full capability comparison](https://xspeedcache.com/comparison/) rather than on entry price, and include the xSpeed Cache Agency lifetime tier in the list as one of the three.

### Is a plugin with a million installs a safer choice?

It is evidence of longevity and of compatibility having been tested widely, which is real. It is not evidence about your stack. Install counts on wordpress.org are buckets rather than measurements, so two plugins showing 1,000,000+ can differ substantially.

### Does either of them work on any web server?

Both do. WP Fastest Cache's readme describes a mod_rewrite-based cache and lists Varnish and CDN integration; WP Rocket's requirements are PHP 7 or higher on Apache, NGINX, LiteSpeed or Windows. If your server choice is the constraint, our [server compatibility notes](https://xspeedcache.com/docs/server-compatibility/) set out what changes on each.

## Conclusion: Pay Once or Pay Every Year?

| If you are… | The pick | Why |
|:---|:---|:---|
| Running one site and want to pay once | WP Fastest Cache Premium, $49 | Cheapest permanent answer in this comparison, and it undercuts us |
| Running one site and want everything automatic | WP Rocket, $59.95/yr | The widest set of optimizations applied without configuration |
| Running three sites on a tight first-year budget | WP Rocket, $119.95/yr | The only price cell where the annual licence wins, by $5.05 |
| Running five to ten sites and paying once | WP Fastest Cache, $175 or $300 | WP Rocket has no tier between three sites and fifty |
| Rebuilding sites on new domains regularly | WP Rocket | Its licence moves; the one-time licence stops moving after a year |
| Running a fleet with AI or MCP access | xSpeed Cache Pro, $249 once for twenty-five sites | Ours. Lifetime pricing and a free MCP server, against a much smaller install base |
| Spending nothing at all | WP Fastest Cache free | A real page cache on any standard host, with no gate on the cache itself |

**What to do this week:**

1. Open your caching plugin's licence page and write down the expiry date, or confirm there is not one.
2. Run the five lapse-test questions against whatever you are paying for now. Ten minutes, vendor documentation only.
3. Check from outside the dashboard that the optimizations you are paying for are still reaching the page.
4. If you want to pay once and run a single site, buy WP Fastest Cache Premium at $49. It is the cheaper permanent answer and we would rather tell you here.
5. If you want a lifetime licence with an AI layer and fleet access, xSpeed Cache Pro is $79 once for one site and $249 for twenty-five, with a 14-day money-back guarantee and 7,000+ installs behind it rather than a million.

If you run this test on a plugin we have not covered, post what its documentation says. The answers are public, they are rarely collected, and the next person pricing a caching plugin will find them useful.
