maestro vs e2e
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.
maestro
YAML-based UI and end-to-end test framework for Android, iOS and web
e2e
AI-driven end-to-end testing framework for web and mobile apps
Verdict
maestro ranks higher, 88 to 85. Of the 4 score parts we measure for both, maestro leads on 2, e2e on 1 and 1 is even.
- Adoptionmaestro leads by 8 points, 82 to 74.
- FreshnessEven at 100.
- Maintenancee2e leads by 12 points, 95 to 83.
- Agent-readymaestro leads by 40 points, 85 to 45: a wide gap.
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
Pick e2e if you are
Teams writing end-to-end tests for web and mobile apps in TypeScript
- Recorded agent actions replay with no model calls until the app changes
- Tests without agent steps need no model at all

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+
e2e
TypeScript test runner where an agent carries out natural-language goals in the app, and ordinary locators and assertions verify the result in the same test. Agent steps that a later assertion checks are recorded and replayed on the next run without model calls until the app changes. Web runs use Playwright (Chromium, Firefox, WebKit); mobile runs use iOS simulators and Android emulators.
Who it is for: Teams writing end-to-end tests for web and mobile apps in TypeScript
Strengths
- Recorded agent actions replay with no model calls until the app changes
- Tests without agent steps need no model at all
- Web via Playwright; iOS and Android via simulators and emulators
- Examples for Next.js, Vite, Astro, Expo, SwiftUI, Compose, Flutter
Weaknesses
- APIs and config can still change between minor releases before 1.0
- CLI sends anonymous telemetry by default; opt-out required
- Agent steps need a model subscription, API key, or local model
- Hosted browser and simulator options depend on third-party services
- no GPU
- Needs Node.js, Playwright, agent-device, iOS simulator or Android emulator (mobile)
- Models: Bring your own subscription, API key, or local model
