Which Magento 2 Full Page Cache Warmer Is Best?
Prices and features verified: October 2026
What matters is how fast pages warm back up after a flush
Magento caches pages, but after every cache flush the first visitor to each URL waits for a cold page. A cache warmer pre-generates those pages so real shoppers always hit a warm cache. Here's which option fits which kind of store.
A warming robot with three load presets and expert tuning, stacking unlimited cache sources, backed by Redis or any cache system, for $179.
A multi-process crawler with page-type and customer-activity queue sources, mobile-theme warming and Varnish coverage reporting, for $239.
Magento's built-in full page cache and Varnish cache pages for free. But with no warmer, the first visitor after each flush waits for a cold page.
Side by side, on what changes the decision
Mirasvit and Amasty are both multi-process cache warmers with a fixed price and a renewal, and both support Varnish and Hole Punch. The table below lists only what changes the pick.
| Mirasvit Full Page Cache Warmer |
Amasty Full Page Cache Warmer |
Native / Varnish | |
|---|---|---|---|
| Price | $179 | $239 | free |
| Proactive cache warming | Warming robot + 3 load presets and expert tuning | Multi-process crawler with manual tuning | None: cold page after each flush |
| Cache sources | Stack unlimited at once: files, sitemaps, crawler, visitor activity | Six queue sources, including customer activity; two can be combined | n/a |
| Cache backends | Varnish, Redis, File and others; force-caches uncacheable pages | Varnish and File; Hole Punch | Varnish or native FPC |
| Reporting | Caching efficiency and average system-load reports | Varnish coverage and page-status reports | None |
| Best for | Most tuning and cache flexibility at the lower price | Varnish-focused stores wanting per-page and mobile control | Zero budget, no proactive warming |
A note on pricing: Mirasvit and Amasty both charge a fixed price that includes a period of updates and support, plus a renewal to keep receiving them. Mirasvit is $179 on Open Source ($459 Adobe Commerce, $719 Cloud), renewing at $108 a year; Amasty is $239. Native Magento full page cache and Varnish are free and built in, but neither warms the cache.

Where each one earns its place
Mirasvit Full Page Cache Warmer: the flexible, lower-price choice
The most tuning and cache flexibility of the two paid warmers, at the lower price: $179.
Strengths
- Warming robot that re-warms a page the moment its cache is cleared
- Three performance presets (High, Medium, Low) plus expert thread, delay and run-time tuning
- Stack unlimited cache sources at once: files, sitemaps, crawler and visitor activity
- Force-cache pages Magento leaves uncacheable, backed by Redis, Varnish, File or any cache system
- One cached page shared across several store views; caching-efficiency and system-load reports
Limits
- No page-type cache source
- No dedicated mobile-user management
- No Varnish coverage report or page-status report
Amasty Full Page Cache Warmer: the Varnish and per-page choice
A multi-process crawler with fine per-page and mobile control, for $239.
Strengths
- Multi-process crawler with page-type and customer-activity queue sources
- Separate warming for the mobile theme
- Varnish coverage report and page-status report
- Hole Punch, a cache-flush log and a certificate-verification toggle
Limits
- Performance tuning is manual (multi-process, delay, queue size) rather than one-click presets
- Higher price than Mirasvit ($239 vs $179)
Native Magento cache and Varnish: the free baseline
Built into every Magento store at no cost. The reason to add a warmer is what native leaves out.
Strengths
- Free and built in: full page cache and optional Varnish
- Caches pages once they're generated, with no extra module
Limits
- No warmer: after any cache flush, the first visitor to each URL waits for a cold page
- No presets, cache-source stacking, or warming reports

Frequently asked questions
Which Magento 2 full page cache warmer is best?
It depends on how you want to control warming. Mirasvit Full Page Cache Warmer gives you a warming robot with three load presets, unlimited stacked cache sources, and Redis or any cache backend with force-caching, for $179. Amasty, at $239, is strong if you run Varnish and want page-type and customer-activity queue sources, mobile-theme warming and coverage reporting. If you have no budget, native Magento cache and Varnish are free, but they don't warm the cache.
Do I need a cache warmer if I already run Varnish or native FPC?
Native full page cache and Varnish store a page once it has been generated, but they don't pre-generate it. After any cache flush (a deploy, a price update, a reindex), the first visitor to each URL triggers a full, slow page build and waits for it. A warmer crawls your pages and rebuilds the cache before real shoppers arrive, so they always hit a warm page.
Mirasvit vs Amasty: how do the two paid warmers differ?
Both are multi-process crawlers that support Varnish and Hole Punch. Mirasvit costs less ($179 vs $239), adds three ready-made load presets, stacks unlimited cache sources at once, and backs the cache with Redis or any system plus force-caching of uncacheable pages. Amasty adds page-type and customer-activity queue sources, mobile-theme warming, and Varnish coverage and page-status reports.
Was Mirasvit Cache Warmer affected by CVE-2026-45247?
Yes, versions below 1.11.12. CVE-2026-45247 is a critical vulnerability that let an unauthenticated visitor inject PHP objects through the warmer's session cookie. It was fixed in version 1.11.12 (May 2026), and version 1.11.16 (September 2026) added further hardening: warmer session cookies are now signed with a per-installation secret, and the storefront cache-clean link is signed too. If you run an older version, update to the current release.
What about LiteMage or free cache warmers?
LiteSpeed's LiteMage includes a crawler, but it requires a LiteSpeed web server, so it only fits that stack. Some free or community cache warmers exist, but they're typically basic scripts without presets, load control, reporting or vendor support. The two paid warmers here are the mainstream supported options.
How does pricing and renewal work?
Both Mirasvit ($179) and Amasty ($239) charge a fixed price that includes a period of updates and support, then a renewal to keep receiving them; Mirasvit renews at $108 a year. Adobe Commerce and Cloud editions can add a surcharge.
