Ramus vs Limrun.Cloud devices your coding agent can drive.
Both host Android emulators that agents reach over a remote MCP server or a CLI, and both give people a browser link to the device. Limrun adds iOS simulators and build sandboxes; Ramus is Android only, at a flat monthly price.

In short.
Ramus fits if
- You want a fixed price with no per-minute meter: Pro is $10 a month for unlimited minutes.
- You want each reviewer on a device of their own or on the same running device as your agent, and their notes back where your agent can read them.
- Your agent should install a new build on a device that is already running, over MCP.
- Android 17 is the version you need.

Where they differ.
Price. Limrun sells credits: 500 a month on Entry, and an Android emulator uses one a minute.2 Ramus sells plans with monthly minutes, and Pro has no minute limit, with two devices at a time.
Platforms. Limrun runs iOS simulators on cloud Macs and has build sandboxes for Xcode and Gradle.1 Ramus runs Android emulators only, and builds Android projects for pull requests.
Who is on the device. A Limrun signed stream URL lets anyone with it watch and use the device without signing in.6 A Ramus link can give each person their own device instead, or join them to yours with what they can do set on the link and everyone's name and cursor shown. It can be revoked on its own.
What comes back. A person on a Ramus link can send a note with a screenshot, the device log and their recent taps, without an account. You reply on the app's page, and your coding agent can read the notes over MCP or the CLI, tell you what it found and, once you agree, fix the bug and reply. See Share a running app.
Installing over MCP. Limrun's remote MCP server installs apps only when it creates a device.4 Ramus's can install a new build on a device that is already running, so an agent keeps the same session between builds.
Questions.
Does Ramus support iOS like Limrun?
No. Ramus runs Android emulators only. Limrun also offers iOS simulators.
Can I use both?
Yes. Both are remote MCP servers, so one agent can have both. Give each server a clear name so the agent picks the right one.
How do the prices compare for one device all day?
Limrun charges by the minute through credits, so cost follows running time. Ramus Pro is a flat $10 a month for unlimited minutes on up to two devices, for your own development and testing.
Can a reviewer use the device without an account?
On both. Ramus share links and Limrun signed stream URLs open in a browser without signing in.
