Both tools re-request your pages so visitors hit a warm cache. The difference is where the requests come from — and whether anyone checks they worked. Here is an honest, feature-by-feature comparison.
Facts checked against cache-warmer.com in July 2026. Spotted something outdated? Tell us and we'll fix it.
A CDN like Cloudflare keeps an independent cache in each of its 300+ data centers. Warming requests sent from one place warm one place.
Crawling your sitemap from a central server fills your page cache and the one edge location that server routes to. The rest of the map stays cold.
Every warming request enters the CDN network in a different region — each one fills the edge location it lands in, on six continents.
Based on both products' public websites and docs. Cache Warmer is a solid, friendly tool — the comparison below is about scope, not quality.
| Capability | warmup.rocks | Cache Warmer |
|---|---|---|
| Multi-region warmingFills the per-location edge caches, not just one | 42 countries, 90+ edge locations per pass | Not advertised — warming appears origin-focused |
| Cache verificationConfirms each response was actually a cache HIT | Records cf-cache-status & equivalents per URL, per run |

| Per-location analyticsHit ratio per CDN data center | Hit ratio & response time per colo | Detailed reports on the top plan |
| CDN auto-detectionCloudflare, Fastly, CloudFront, Akamai, bunny.net, CDN77 | Detected from response headers, zero config | CDN-agnostic, no per-CDN reporting advertised |
| Sitemap auto-discoveryNested sitemap indexes resolved before every run | Yes | Yes |
| Scheduled runs | Every 1–3 h depending on plan | Yes, user-defined |
| Deploy hooks & CIRe-warm right after a deploy purges the cache | Webhook + official GitHub Action | Trigger after site update |
| Mobile cache variantSecond warm pass with a mobile user agent | On Boulder & Summit plans | Not advertised |
| WAF / bot-protection guidanceDocumented user agent, warm header, block alerts | Docs + email alert when runs get blocked | Not documented publicly |
| Free trial | 7 days, full features | 7 days, no credit card |

Cache Warmer facts from cache-warmer.com (July 2026). Both products evolve — always verify against their current site.
A warming request that gets blocked by a WAF, hits a DYNAMIC page or lands on
an evicted object does nothing — silently. That's why we record the cache status of
every single response and alert you when something stops working.
your traffic is international, you're on Cloudflare/Fastly/CloudFront & friends, and you want proof that the edge cache near every visitor is warm — with per-location hit ratios, deploy hooks and WAF-block alerts.
your audience is in one region, you mainly want your origin's page cache kept warm at a low entry price, and per-edge-location coverage or verification isn't a requirement.
Tiered caching helps — a miss at a small edge location is fetched through a larger upper-tier data center instead of your origin. But upper tiers only cache what flows through them. Warming from many regions fills both the edges and their upper tiers; warming from one place fills one path. Our measurement of 408,000 requests shows what cold colos cost: a miss was 3.5× slower than a hit at the median.
They're different budgets for different jobs. A single warmup.rocks pass sends one request per URL per region — that's how the per-location caches get filled. Our plans meter pages per run and monthly warming traffic instead of a flat page count, so the multi-region fan-out stays predictable and honest.
Sure. Both tools are installation-free — they only send HTTP requests to your public pages. Run our free cache checker before and after a trial week and compare the hit ratios yourself; that's more convincing than any comparison page.
We wrote it, so read it critically — but every claim about Cache Warmer comes from their public website and pricing page as of July 2026, and we say "not advertised" rather than "impossible" where their docs are silent. If something is wrong or outdated, tell us and we'll correct it.
