Ramus Cloud Android Emulator Streamlines Mobile Development
Cloud-based Android emulation eliminates local setup with GitHub and AI integrations.
1Cloud-native Android emulation
Ramus provides hosted Android device emulation accessible via browser or CLI, eliminating local Android Studio/SDK setup. It supports native Android, Jetpack Compose, Expo, React Native, and Flutter apps. Developers can upload APKs or connect GitHub repos for automated testing flows. The service runs in isolated virtual machines with discarded sessions for security. Currently in free alpha, it offers core functionality without charge.
2GitHub PR preview integration
Ramus automatically builds GitHub branches in isolated environments and attaches live preview links to pull requests. Reviewers can interact with app changes directly in browsers without local setup. The integration uses short-lived GitHub tokens scoped to selected repositories, maintaining security without requiring secrets unless part of protected workflows. This streamlines code review processes for distributed teams.
3AI agent tooling support
The platform enables AI agents like Claude Code and Codex to control virtual devices for automated testing. Agents can monitor app behavior, take screenshots, and share control via device links. The ramus-cli tool provides session management, APK uploads, input simulation, and log access. This integration bridges AI-assisted development with physical device validation for UI/behavior testing.
4Security and privacy architecture
Each session starts in an isolated clean VM with discarded state afterward. Ramus stores only limited metadata, avoiding persistent recording of session contents or videos. Builds use minimal GitHub token permissions. The architecture eliminates need for developer credentials in most workflows while maintaining audit capabilities through metadata retention for operational purposes.
5Free alpha access tiers
Anonymous users get 60-minute CLI trials with one active session and 150MB APK support, limited to three trials daily per IP. Signed-in accounts gain two concurrent sessions, 300MB APKs, browser uploads, and full GitHub PR previews. All core features remain free during alpha, including agent integrations and local workflow support, with capacity constraints guiding early adoption patterns.
6Target developer profiles
Ramus serves Android-focused teams seeking to accelerate testing without maintaining local device labs. It benefits organizations conducting code reviews/QA needing interactive PR previews. AI-assisted development teams gain physical emulation for automated testing. Cross-platform Android teams (Flutter/React Native) appreciate unified support. iOS-focused teams must wait as Android remains the sole supported platform currently.
7Current platform limitations
The service exclusively supports Android emulation, excluding iOS and other platforms. Teams requiring long-running sessions or large device fleets may need alternative solutions until Ramus expands capacity. The alpha phase imposes APK size and concurrency limits. While suitable for most development workflows, stress testing scenarios might require supplemental infrastructure during this early stage.
8Workflow transformation potential
Ramus centralizes builds, previews, and automated testing in the cloud, reducing setup friction. Its strongest value emerges in PR-based workflows and AI-assisted development pipelines. As the platform matures, expanded capacity and pricing models could position it as essential Android toolchain infrastructure. The solution particularly benefits teams prioritizing rapid iteration, collaboration, and tight code-to-preview integration.
