The Playground

Pre-flight a bench.
Right here, right now.

This is the real linter — the same 20 checks that run in CI and on the bench — compiled to WebAssembly and running entirely on your machine. A bench config that trips 7 rules is preloaded. Run it, break it, fix it, watch the verdict change. Nothing you paste ever leaves your browser.

AIR-GAPPED BY DESIGN — the linter executes locally via WebAssembly. No network calls, no telemetry, no upload. The downloadable tool does the same on an actual air-gapped bench.

Like what it catches? Put it in front of your bench.

One auditable file, zero dependencies, runs fully offline. Free during early access — and the whole check catalog + config spec is open (MIT).
