Describe it in plain English, Drizz tests it on real devices
Describe the flow the way you use the app — no selectors or scripting required.
Tests understand the UI the way a person does, so dynamic interfaces and critical flows stay covered.
Steps adapt and repair themselves when the UI changes, cutting maintenance to near zero.
Runs on real iPhones and Androids with iOS and Android covered from a single test written once.

Cloud mobile development with agents and runtime evidence
Programmable iOS and Android environments on fast cloud infrastructure that remove dependency on any single local machine.
Add Revyl to Cursor, the CLI, GitHub Actions, MCP or your API so agents get live mobile devices to run and verify the code they write.
Every run feeds Atlas, a continuously updated map of what your app does, what changed and what is covered — runtime truth instead of stale docs.
Verify changes through the same visible workflows users experience, with run history and artifacts retained for evidence.
