NoFlake Documentation

AI-powered E2E tests that write themselves. Three commands. Zero babysitting.

What is NoFlake?

NoFlake is a developer-first CLI tool that reads your codebase — your framework, database schema, routes, and auth patterns — and generates a complete Playwright E2E test suite. When tests break because your code changed, NoFlake patches them automatically.

🔒 Your code is safe. NoFlake never modifies your application source code. It reads your routes, schemas, and auth patterns (read-only), then writes only to tests/e2e/ and .noflake/. Your src/, app/, pages/, and all other source directories are never touched.

What's Included

noflake init — Set up your project with Playwright config, test directories, state folder, and optional git hook
noflake write — AI-powered test generation with self-healing (scans your codebase, generates Playwright tests, retries on failure)
noflake update — Diff-based test patching (reads git changes, patches affected tests, optional auto-commit)
noflake run — Test execution with reports and optional --fix for AI-powered failure repair
noflake license — Manage your subscription (activate, check status, deactivate)
