35 coins and networks, each on its own page with live price data where our free feed carries it and 1300-1700 words of unique editorial: how the protocol works, real use cases, honest tradeoffs, related coins, FAQ. Editorial discipline: zero memecoins.

WHY THIS EXISTS/ A NOTE FROM THE TEAM

Developer tools have a marketing problem. Most landing pages for dev resources are full of stock photos, signup walls, and analytics pixels that fire before you read the headline. The good free tools are scattered across personal sites, GitHub Gists, and bookmarks shared on Hacker News. The good cheatsheets are buried under SEO-optimized rewrites of Stack Overflow.

This hub is the version we wanted to find when we were learning. Tools that load in under 200ms and don't phone home. Articles that show real code. Cheatsheets that fit on one screen. No signup, no tracking, no popup asking for your email.

If you find something broken, a tool that's missing, or a reference that would help your daily work, email [email protected]. Suggestions get read and usually answered within a day or two.
