What it does

A framework for testing and automating Chromium, Firefox and WebKit with one API, including a test runner, auto-waiting, tracing and code generation, with bindings for TypeScript, Python, Java and .NET.

You need reliable end-to-end tests across all major browser engines, or browser automation for scripts and AI agents.

Watch out

It uses patched browser builds downloaded per version, which adds disk use and can differ slightly from the browsers users run.

Open-source alternatives to Playwright

1. 1
   Browser Use browser-use

   Open-source Python library for AI browser agents, plus Browser Use Cloud: stealth browsers and a hosted agent API.

   Building block Usable You are building an AI agent that has to complete tasks on websites that have no API, and you accept slower, less predictable runs than a scripted Playwright test.

   CloakBrowser CloakHQ

   Stealth Chromium that passes every bot detection test. Drop-in Playwright replacement with source-level fingerprint patches. 50+ tests passed.
