About this tool
Compile TypeScript in your browser and run the JavaScript in a sandbox. Free, no signup, nothing uploaded. TypeScript Playground runs in the browser on DevTools. There is no signup, and your input stays on this device unless the tool explicitly performs a live network lookup.
What this tool does not do
- TypeScript Playground is a free in-browser utility, not a hosted API. It does not keep server-side history and is not a substitute for production verification in your own stack.
