What can I test with Ramus?

You can upload your Android APK builds and run them in a real Android emulator in your browser. You can test a flow, share a working preview with reviewers, give coding agents like Claude Code or Codex a device to control, and preview pull requests with live app previews.

Do I need Android Studio or local setup?

No. Ramus runs Android emulators in the cloud, and you can test directly in your web browser with no local setup needed.

What happens to my data and builds after I finish testing?

Build environments are discarded after the build, and device state is discarded when the session ends. Ramus does not use your Customer Content for advertising, model training, or product development.

How long do watch links stay valid?

Watch links stay valid for 72 hours by default, though that does not keep a device running for 72 hours.

Can I try Ramus without signing up?

Yes, you can try Ramus from your terminal with no account needed for the demo. Run npx ramus-cli trial to get a device for 15 minutes.
