Hey PH! I built TryJS because I wanted a JS/TS playground that felt instant — no loading spinners, no account walls, no server-side execution.
Everything runs in your browser: TypeScript is transpiled via Sucrase, npm packages load from esm.sh, and code executes in a sandboxed iframe.
The whole UI is ~6KB gzip (Preact + Signals). I'd love your feedback — what would make this more useful for you?
