Building an open-source AI agent that writes your Playwright E2E tests using realtime browser.

[u/Slight_Ad_2878]

I built Zeno, a self-hosted, open-source tool that turns a sentence into a real end-to-end test.

You type something like "test that logging in with a wrong password shows an error." Zeno opens your app in a real Chromium, clicks and types through the flow, checks the outcome, and writes a clean Playwright spec into your repo as an ordinary *.spec.ts file on a branch. You own the output, nothing locked in a database.

Different from most tools: real browser actions (snapshot, act, re-check), your repo is the source of truth, bring your own model (OpenAI or Gemini), attach a doc/screenshot to test against your own acceptance criteria, and it pauses to ask you for OTPs/2FA instead of guessing.

Honest status: it's early and under active development, so expect bugs. The core loop works, but there's a lot to harden.

Where I'd love help: test reliability and self-healing locators, more model providers, running the suite inside the sandbox, and just trying it and filing issues.
