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

Junban's answer:

It applies one single mechanic — "did this come out before or after?" — to everything: music (with clips built into the app, no Spotify needed), movies, history, sport, and sagas like Harry Potter, Star Wars or One Piece. Physical games like Hitster or Timeline each cover one theme per box; Junban covers 50+ themes in one free app, playable solo, offline, or with up to 4 players online.

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.

Junban's answer:

No card box to buy, no Spotify subscription required, and no content limit: a physical deck gets memorised, an app gets updated. Junban also does what boxes can't — ranked solo play with a worldwide leaderboard, daily challenges, offline mode, and remote multiplayer with friends who aren't in the room.

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

Junban's answer:

Anyone who enjoys quiz nights: friends at a party, families with mixed ages (kids can beat their parents on the right theme), and solo players on their commute. Fans of Hitster and Timeline looking for a lighter, subscription-free version are right at home.

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.

Junban's answer:

Junban is built by a French solo indie developer who loved Hitster game nights but not the card box + streaming subscription it requires. He rebuilt the core loop as an app with the clips built in, then realised the before/after mechanic works for movies, history and sagas too — it now has 50+ themes in 6 languages.

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.

Junban's answer:

Ionic + Capacitor (single React codebase for iOS and Android), Supabase for the backend and leaderboards, RevenueCat for in-app purchases.
