About warmup.rocks and React Spring

In their own words, as submitted to SaaSHub.

warmup.rocks
React Spring

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...

Features and specs

What each product offers, as listed by its team.

warmup.rocks 5 features
React Spring 5 features
  • Free Resource
    Warmup.rocks offers a collection of button hover effects and micro-interactions completely free of charge, making it accessible to developers and designers of all budgets.
  • Copy-Paste Code
    The site provides ready-to-use CSS and HTML code snippets that can be easily copied and implemented directly into projects, saving development time.
  • 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.
  • Flexible Animations
    React Spring offers a highly flexible animation system that can handle various types of animations, from simple transitions to complex sequences, making it ideal for a wide range of animation needs.
  • Declarative API
    The library provides a declarative API, which aligns well with React's component-based architecture, allowing developers to create animations in a straightforward and intuitive manner.
  • Performance Optimized
    React Spring is designed with performance in mind, using physics-based calculations to ensure smooth and realistic animations, which can enhance user experience without sacrificing performance.
  • Interoperability
    React Spring is interoperable with other libraries and can easily integrate into existing projects, allowing developers to incrementally add animations without significant refactoring.
  • Active Community
    The library benefits from an active community, providing ample resources, community support, and regular updates which help in keeping the library up to date with the latest best practices.

Possible disadvantages

  • Learning Curve
    For developers new to physics-based animation systems, React Spring can have a steep learning curve, requiring time to understand its concepts and implementation details.
  • Complexity
    For simple animations, React Spring may be considered overkill, introducing unnecessary complexity compared to CSS transitions or other simpler animation solutions.
  • Bundle Size
    Inclusion of React Spring can increase the bundle size of an application, which could be a concern for performance, especially in projects where minimizing bundle size is critical.
  • Limited Native Support
    As React Spring is specifically tailored for web-based animations, it has limited support for native applications compared to some other animation libraries that cater to both web and native platforms.
  • Dependency Management
    Using React Spring introduces an additional dependency in the project, which requires management and updating to maintain compatibility with React and other package updates.

Questions & Answers

As answered by people managing warmup.rocks and React Spring.

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.
