Which to pick
- Pick Hydra Lab when
- Your organisation has a pile of test devices and wants an in-house device cloud instead of paying for BrowserStack or Firebase Test Lab.
- Pick Tracely when
- You run AI agents in production and want real failures turned into tests that gate your pull requests.
Side by side
A self-hosted platform that turns your own phones and machines into a shared test lab, running Espresso, Appium and exploratory tests and showing results centrally.
Grades AI agent traces as they arrive, clusters failures into issues, freezes bad runs into replayable regression tests, and blocks pull requests that would bring them back. Includes an API, worker, UI and a Python SDK.
There are no releases, setup is through a wiki, and the repository has been renamed, which makes its future direction unclear.
Under a month old with no release, and the full stack needs Postgres, ClickHouse, Redis and MinIO.
