Small sharp tools you own.

One-time-purchase developer tools built on Cloudflare Workers. You get the full source, deploy it yourself on the $5 plan, and it runs forever. No subscriptions, no phone-home, no accounts with us.

House rules: every claim on a product page is real, every price is one-time, and every product ships with the full TypeScript source and a license that lets you build anything except resell the tool itself.

How these get built

Each tool starts as a real need, survives an evidence gate that kills most ideas, and ships only after its tests pass. The process is public: read the build story that started it all, including everything that failed.
