playwright vs maestro
Two of the top projects in Code review and testing, side by side: who leads on each score part and who each one suits, then setup, license, activity and what each review found.
playwright
Cross-browser automation and end-to-end test framework for Chromium, Firefox and WebKit
maestro
YAML-based UI and end-to-end test framework for Android, iOS and web
Verdict
playwright ranks higher, 94 to 87. Of the 4 score parts we measure for both, playwright leads on 2, maestro on 1 and 1 is even.
- Adoptionplaywright leads by 20 points, 99 to 79: a wide gap.
- FreshnessEven at 100.
- Maintenanceplaywright leads by 16 points, 99 to 83: a wide gap.
- Agent-readymaestro leads by 40 points, 85 to 45: a wide gap.
Pick playwright if you are
Engineers writing browser tests or automation, or giving agents browser access
- One API covers Chromium, Firefox and WebKit on Linux, macOS and Windows, headless or headed
- Test runner has auto-waiting, retrying assertions, per-test browser contexts and parallel execution
Pick maestro if you are
Mobile and web developers and QA engineers automating UI tests
- Single binary install; no drivers or SDK needed in the app under test
- One YAML syntax covers Android, iOS, web, React Native, Flutter and hybrid apps

playwright
Playwright drives Chromium, Firefox and WebKit through one API, used for end-to-end tests with the Playwright Test runner, for standalone scripts such as screenshots, PDFs and scraping, and as a browser tool for AI agents. The agent paths are a CLI for coding agents and an MCP server that exposes pages as accessibility snapshots. Bindings exist for TypeScript/JavaScript, Python, .NET and Java.
Who it is for: Engineers writing browser tests or automation, or giving agents browser access
Strengths
- One API covers Chromium, Firefox and WebKit on Linux, macOS and Windows, headless or headed
- Test runner has auto-waiting, retrying assertions, per-test browser contexts and parallel execution
- Trace Viewer records DOM snapshots, network requests and console logs; VS Code extension adds codegen
- Agent tooling: MCP server uses accessibility snapshots, so no vision model is needed
Weaknesses
- Browser binaries must be downloaded separately with `npx playwright install`
- MCP server and CLI live in separate repos, not in this one
- Agent features are secondary; the core is a testing and automation library
- no GPU
- Needs Node.js, Browser binaries via npx playwright install
maestro
Maestro runs UI and end-to-end tests written as flat YAML command lists (launchApp, tapOn, assertVisible) against Android, iOS and web apps, driving them through the platform accessibility layer. It installs as a single CLI binary and also ships an MCP server (`maestro mcp`) so coding agents can control a live device and write flows. Flows run on emulators, simulators, browsers and physical Android devices.
Who it is for: Mobile and web developers and QA engineers automating UI tests
Strengths
- Single binary install; no drivers or SDK needed in the app under test
- One YAML syntax covers Android, iOS, web, React Native, Flutter and hybrid apps
- Built-in MCP server in the CLI works with Claude Code, Cursor, Codex and others
- Automatic waiting and flakiness tolerance remove manual sleep calls
Weaknesses
- Physical iOS devices are not supported
- Requires Java 17 or higher on the host
- Maestro Studio IDE is free but closed source
- Parallel execution at scale needs paid Maestro Cloud
- no GPU
- Needs Java 17+
