Output appears here — hit Run.

Code runs in a sandboxed, isolated executor (Piston, CPU/time-limited) — your code is sent to that runner, so don't paste secrets. The tool is bring-your-own-runner: the public Piston is now whitelist-only, so self-host it in one command (docker run -p 2000:2000 ghcr.io/engineer-man/piston) and set PLAYGROUND_RUN_URL(add PLAYGROUND_RUN_TOKEN for a hosted runner).
