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.

Javascript Minifier features and specs

  • Reduced File Size
    Minifying JavaScript reduces the file size by eliminating unnecessary characters such as whitespace and comments, which can lead to faster downloads and improved load times for web pages.
  • Improved Page Performance
    By reducing the file size of JavaScript files, the overall performance of web pages can be enhanced as browsers can download and execute scripts more quickly.
  • Bandwidth Savings
    Minified JavaScript files consume less bandwidth, which is beneficial for both server load handling and users with limited data plans or slower internet connections.
  • Enhanced User Experience
    Faster load times and improved performance contribute to a better user experience, as visitors encounter fewer delays and smoother interactions with the web page.

Possible disadvantages of Javascript Minifier

  • Loss of Readability
    Once minified, JavaScript code becomes much harder to read and debug due to the removal of whitespace, comments, and the shortening of variable names.
  • Debugging Challenges
    Debugging minified code can be problematic because the transformation makes it difficult to correlate minified code with the original source code, potentially requiring source maps for effective debugging.
  • Maintenance Issues
    If the source code is lost or not managed properly, maintaining or updating the minified code becomes challenging due to its lack of readability.
  • Compatibility Concerns
    In rare cases, minification may introduce errors or bugs if certain patterns or specific constructs are not handled correctly by the minification tool, potentially leading to runtime issues.

Questions & Answers

As answered by people managing warmup.rocks and Javascript Minifier.

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.
