About Playwright
Playwright is an open-source framework for automating web browsers. It drives Chromium, Firefox and WebKit through one API, and it is used for end-to-end tests, scripts and AI agent workflows.
What it does
Playwright runs browser tests that click, type and check pages the way a user would. It waits for elements to be ready before each action, which helps keep tests steady. Every test runs in a fresh browser context, so tests do not share state. Playwright also ships an MCP server and a CLI, which let AI agents control a browser through structured page snapshots.
Key features
- Test runner with assertions, tracing and parallel runs
- Automatic waiting before each action
- Fresh browser context for every test
- Locators based on roles, labels and test IDs
- MCP server and CLI for AI coding agents
Who it's for
QA engineers and developers who test web apps across several browsers. It also suits teams that run browser scripts in CI pipelines or want an agent to drive a browser.
Pricing and good to know
Playwright is open source under the Apache-2.0 licence and free to use. It supports TypeScript, Python, .NET and Java. It installs through npm, and tests can be sharded across several machines to speed up CI runs.
