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.
Features
Free tools, no signup: multi-location cache checker and website speed test.
Nothing to install: no plugin, no DNS change. 7-day free trial, plans from $15/month.
SpawnWP is a free and open-source, self-hosted WordPress development lab for creating isolated, disposable WordPress environments on your own Debian or Ubuntu server.
It is designed for development, testing, debugging, plugin/theme evaluation, demos and experimentation โ not as a traditional hosting control panel.
Each WordPress instance runs in its own isolated Docker stack and can be created, reset, snapshotted or destroyed whenever needed. SpawnWP also includes a web-based cockpit for managing environments without having to work exclusively from the command line.
Key features include:
Unlike hosted services such as InstaWP or TasteWP, SpawnWP runs entirely on infrastructure you control. There are no per-site fees, artificial site limits or recurring SaaS subscriptions imposed by SpawnWP itself โ your limits are essentially the resources available on your server.
SpawnWP started as a personal tool for quickly spinning up WordPress test environments and was later released publicly as an MIT-licensed open-source project.
It is particularly useful for WordPress developers, agencies, plugin and theme authors, QA testers and anyone who frequently needs clean WordPress installations without repeatedly configuring servers from scratch.

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:

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:
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.

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