Autonoma vs Refraction

Autonoma is an open-source testing platform that sends agents through your web and mobile apps in real browsers to catch regressions on every pull request. You start with a single CLI command, and the agents map pages, user flows, and edge cases without you writing Playwright or Appium scripts.

The platform sits above low-level test frameworks as an execution layer. Agents understand what your app does, not just where buttons sit, so tests adapt when the UI changes instead of breaking on every layout tweak. You wire real data through an SDK so tests seed and tear down accounts the same way your production code does.

Engineering teams at companies like Vercel, Superhuman, and Mercor use Autonoma to run end-to-end checks on preview deploys before merging. It integrates with GitHub, Vercel, Linear, and common web and mobile stacks including React, Next.js, Flutter, and React Native.

The managed cloud runs tests in parallel on real browsers and devices, while the fully open-source version can be self-hosted on your own infrastructure with no usage limits.
