Zeitaku playground

Paste a Playwright test. Zeitaku parses it with the TypeScript compiler, finds every hard-coded waitForTimeout, checks whether each sleep is guarding a "should NOT happen" assertion, and rewrites only the safe ones into a network-aware wait. Everything runs in your browser; nothing is uploaded.

Your test

Green: replaced with __zeitaku.idle(page), which continues when the page's network is actually quiet. Amber: left alone on purpose.

Every sleep found

This page runs the same findSleeps / fixCode logic as the CLI (src/core/sleeps.ts), with the TypeScript 5.9 compiler loaded in the page. The network-aware wait itself needs a real browser under test, so it isn't run here: see the benchmarks. · GitHub · Portfolio
