e2e is TesterArmy's open-source agentic end-to-end testing framework for web, iOS and Android apps.
Tests are written in TypeScript and mix natural-language goals that an agent drives with deterministic locators and assertions, and verified agent steps are replayed without model calls until the app changes.
- 01
Natural-language agent steps (`agent.act`, `agent.assert`) alongside deterministic locators and assertions
- 02
Record-and-replay of verified agent actions with no model calls until the app changes
- 03
Web engine on Chromium, Firefox and WebKit via Playwright; mobile engine on iOS simulators and Android emulators
- 04
`e2e mcp` server so coding agents like Claude Code and Cursor can drive a real browser or simulator
- 05

Free
e2e is free and open source under the Apache 2.0 license; agent steps use your own model provider, API key, local model or existing ChatGPT, GitHub Copilot or SuperGrok subscription, and tests without agent steps need no model.
Best for
Teams that want AI-driven end-to-end tests for web and mobile apps without giving up deterministic assertions or paying for model calls on every run.
Not ideal for
Teams that need a stable API today, since e2e is pre-1.0 and APIs and config can still change between minor releases.
