Ramus Reviews — Discover what people think of this product.

Ramus is a browser Android emulator for developers and for the coding agents they work with. It runs stock Google Android images on a self-hosted fleet and streams them over WebRTC, so a device is usable within about a second of clicking and disappears when you are done.

Three ways in. Upload an APK from the dashboard and tap through it in the browser, with screenshots and device logs beside the screen; send a watch link and a reviewer opens the same device with no account or install. Connect the GitHub App and Ramus builds supported pull requests (Expo, React Native, Flutter, and Gradle-based Kotlin, Java or Compose apps) and posts one self-updating comment with a preview link. Or give the device to an agent: the ramus-cli npm package and a Streamable HTTP MCP server expose the same tools, so Claude Code, Codex, Cursor or any MCP client can start a session, inspect the UI tree, tap, type, capture the screen, and read logcat, while you watch or take over in the browser.

Ramus is Android-only today, free during alpha, and built on its own hardware rather than a rented device cloud.
