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

  • Sitemap auto-discovery, nested sitemap indexes resolved before every run
  • CDN auto-detection: Cloudflare, Fastly, CloudFront, Akamai, bunny.net, CDN77
  • Scheduled runs every 1-3 hours depending on plan
  • Deploy hooks + official GitHub Action: re-warm right after your CI purges the cache
  • Mobile cache variant (second pass with a mobile user agent)
  • Email alerts when a WAF rule blocks warming runs

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.

StackBlitz features and specs

  • Speed
    StackBlitz is known for its quick load times and fast editing capabilities, making it ideal for rapid development and testing.
  • Ease of Use
    The interface is intuitive and user-friendly, allowing developers to get started quickly without a steep learning curve.
  • Zero-Setup
    Users can write, compile, and run code directly in the browser without any setup or configuration required.
  • Integrations
    StackBlitz integrates seamlessly with GitHub, allowing for easy import and export of repositories.
  • WebContainers
    StackBlitz uses WebContainers to run Node.js applications in the browser, providing a near-native development experience.
  • Collaboration
    Real-time collaboration features allow multiple users to work on the same project simultaneously, similar to Google Docs.

Possible disadvantages of StackBlitz

  • Limited Plugins
    Unlike traditional IDEs like VSCode or IntelliJ, StackBlitz has a limited ecosystem of plugins and extensions.
  • Online Dependency
    StackBlitz requires an internet connection to function, which can be a limitation for developers who need to work offline.
  • Performance
    For very large projects or those requiring extensive computational resources, performance may degrade compared to local development environments.
  • Mobile Accessibility
    While StackBlitz is accessible on mobile devices, the user experience is not as optimized as it is on desktop browsers.
  • Limited Framework Support
    Although StackBlitz supports many popular frameworks, it doesn't support all frameworks or versions, which could be limiting for some projects.
  • Storage and Persistence
    Files and data are stored in the cloud, which might raise concerns around data privacy and persistence for some users.

Questions & Answers

As answered by people managing StackBlitz and warmup.rocks.

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.

  • RS-X: Framework-agnostic reactive state and expressions for JavaScript/TS
    Managing reactive state and dependent computations in JavaScript can get complex, especially when combining asynchronous and synchronous data. RS-X is a library that allows you to bind expressions to plain objects and makes the parts of the model used by those expressions fully reactive. Dependent computations automatically update when the underlying data changes. RS-X is framework-agnostic. While it can drive UI... - Source: Hacker News / 6 months ago

    I like htmx, LiveView, React and Solid. They are great at different points, so I try to combine them in Solv (Stateless Offline-capable LiveView) and write a prototype to show the benefits. Solv's main idea is that stateless servers keep client's state in a volatile cache. It enables server components that are also interactive, which is best of both worlds between LiveView and htmx.
