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.

pyvim features and specs

  • Keyboard Shortcuts
    PyVim supports Vim-style keyboard shortcuts, allowing users familiar with Vim to perform efficient text editing without needing to learn a new set of commands.
  • Extensibility
    Being based on the prompt-toolkit, PyVim is highly extensible and can be customized to suit specific user needs, allowing for a tailored editing experience.
  • Lightweight
    PyVim is designed to be a lightweight Python-based text editor, which can be advantageous for users seeking a minimalist tool with basic functionality.
  • Integration with Python
    As a Python-based tool, PyVim can easily integrate with other Python libraries and tools, making it suitable for Python developers.

Possible disadvantages of pyvim

  • Limited Features
    Compared to the full version of Vim, PyVim lacks many advanced features and plugins, which might be a drawback for users needing more complex functionality.
  • Stability Concerns
    As a project, pyvim might not be as extensively tested or stable as more established text editors, potentially leading to bugs or other issues.
  • Lack of Community Support
    PyVim is a less common choice compared to other editors, which can mean limited community support and fewer resources for troubleshooting or learning.
  • Command Line Interface
    PyVim operates as a command-line tool, which may not appeal to users who prefer graphical user interfaces for text editing tasks.

  • Visual Preview
    Users can see live previews of each animation effect before deciding to use it, allowing for quick visual assessment without needing to test code first.
  • Variety of Effects
    The collection includes numerous different button animation styles, giving developers multiple creative options to enhance user interface interactivity.
  • Lightweight Implementation
    The animations are typically built with pure CSS or minimal JavaScript, making them lightweight and easy to integrate without heavy dependencies.

Analysis of pyvim

Overall verdict

  • Pyvim is a decent, functional Vim clone written in pure Python using the prompt_toolkit library, useful mainly as a demonstration of prompt_toolkit's capabilities rather than as a full-fledged replacement for Vim in daily production use.

Why this product is good

  • Built on prompt_toolkit, showcasing how powerful terminal UIs can be created in Python
  • Implements many core Vim features like modal editing, basic commands, and syntax highlighting
  • Lightweight and easy to install via pip, with readable Python source code
  • Great for developers who want to study or extend a Vim-like editor in Python
  • Cross-platform since it relies on Python rather than C bindings

Recommended for

  • Python developers interested in learning how terminal-based editors work
  • Users who want a hackable, Python-based Vim clone for experimentation
  • Developers exploring prompt_toolkit for building CLI applications
  • Not recommended as a primary editor for professional or heavy-duty coding work due to missing advanced features and plugins compared to real Vim/Neovim

Questions & Answers

As answered by people managing pyvim 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 São 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 3.5× 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.
