Follow one e2e checkout test from a plain-language goal to an agentic assertion, a locator check, and a cached replay that heals itself when the UI changes.
e2e 0.23 includes agent steps that run on your Claude Code login, real iOS and Android devices on BrowserStack, e2e doctor, MCP test runs, and an engine protocol.
Announcing our new brand identity and $8M seed funding.
e2e's mobile engine runs on Callstack's agent-device. Follow one Expo test from a plain-language goal to exact assertions and cached replays on iOS and Android.
e2e is our open source, Apache-2.0-licensed testing framework. You write exact locators where you need certainty, give the agent a goal where scripting every click isn't worth it, and run the same suite on web, iOS, and Android. Start with npx e2e init.
We raised $1.2M in pre-seed funding. We are building TesterArmy so teams can check that their web and mobile apps work as fast as they can change them.
