A CDN isn't one cache. It's hundreds of independent ones, and most of them are cold.

Cloudflare alone runs 300+ data centers, and each keeps its own cache. A page cached in Frankfurt is still ice cold in Tokyo, so the first visitor per region pays the full origin round trip. In our measurement of 408,000 CDN requests, a cache miss was 3.5x slower than a hit at the median.

warmup.rocks fixes that by requesting your pages from 42 countries on 6 continents on a schedule. Each request enters the CDN network in a different region and fills the edge location it lands in: 90+ locations per warming pass.

What makes it different: verification. We record the cache status (cf-cache-status, x-cache and equivalents) of every single response and show you the hit ratio per edge location, per run. Warming without verification is hoping.

Questions & Answers

As answered by people managing warmup.rocks and OpenPlotter.

Who are some of the biggest customers of your product?

warmup.rocks's answer

  • this:matters GmbH (the Swiss web agency behind the product, running client sites through it)

What makes your product unique?

warmup.rocks's answer

Most cache warmers run from one server, so they only warm the one CDN edge location that server happens to hit. CDNs like Cloudflare cache per data center, 300+ of them, and a HIT in Frankfurt says nothing about Singapore.

warmup.rocks is different:

  • Warms from 42 countries on 6 continents, so the cache gets filled where your visitors actually are
  • Verifies every response (cf-cache-status, x-cache) instead of just firing requests and hoping
  • Shows hit ratio per edge location, so you see whether warming actually works
  • Nothing to install: no plugin, no script tag, no DNS change

Why should a person choose your product over its competitors?

warmup.rocks's answer

Three reasons:

  • Geography. Competitors warm from a single region. We warm from 42 countries, which is the whole point of a CDN cache.
  • Verification. We read the cache status header of every single response and report the actual hit ratio per location, so you see whether warming works instead of taking it on faith.
  • Deploy integration. A deploy hook or our GitHub Action re-warms the cache right after you ship, which is exactly when it's coldest.

Plans start at $15/month with a 7-day free trial.

How would you describe the primary audience of your product?

warmup.rocks's answer

Developers, agencies and store owners who run sites behind a CDN (Cloudflare, Fastly, CloudFront, Akamai, bunny.net) and serve visitors in more than one region. Typical cases:

  • WordPress/WooCommerce sites where preload plugins stop at the server cache
  • Shopify and Magento stores with a long product tail that never stays warm on its own
  • Anyone whose deploys purge the edge cache and leave the first visitor per location with a slow load

What's the story behind your product?

warmup.rocks's answer

I run a web agency in Switzerland, and for years I believed our sites were fast because we put them behind Cloudflare and saw HIT in the headers. Then I measured from other continents: pages that loaded in milliseconds from Zurich took multiple seconds from Tokyo or Sรฃo Paulo, because each edge location keeps its own cache and most of them were cold.

I built a warmer for our own client sites first, then measured 408,000 CDN requests and found a miss is 3.5ร— slower than a hit at the median. That data convinced me this should be a product.

Which are the primary technologies used for building your product?

warmup.rocks's answer

  • Node.js + TypeScript with Hono as the web framework
  • SQLite for storage
  • Astro for the public site, vanilla JavaScript for the dashboard
  • Warming requests go through dedicated datacenter proxies in 42 countries

The whole thing runs on a plain VPS behind Cloudflare, which keeps it fast and cheap without a pile of infrastructure.
