Free Online Tools
Small, genuinely useful web tools — fast, no sign-up, and privacy-friendly by design. Your files never leave your device. The one exception is the Core Web Vitals test, which has to run on our server because a browser cannot measure a page on another domain — and we say so on the page.
Available tools

Write TypeScript in your browser and have it checked instantly: type errors with line numbers and error codes, the compiled JavaScript beside them, one click to run it. The compiler runs locally, no install needed.
