Client applications
Each platform gets its own application, written natively rather than one codebase wrapped four times. It behaves the way that platform's users expect.
Marram Software LLC · Wyoming, United States
Network software, engineered to hold.
We build native connectivity and privacy applications for desktop and mobile, and the backend platform that runs them.
What we build
Three layers, all ours to maintain: the network core, the client applications, and the service platform.
Network core
A modified build of mihomo, an open-source network core, maintained and extended by us. All four client applications run on that one build.
Service platform
We run the subscription, provisioning and device-management services behind the applications. We also run the control plane for our node fleet and a set of edge services.
Platform coverage
Current development status, stated plainly.
macOS Universal binary, macOS 12 and later Shipping
Android Android 7 and later, arm64 Shipping
iOS iOS 17 and later In development
Linux Command line and terminal interface In development
Status as of August 2026.
How we work
Networking software fails in ways users cannot see, so our engineering goes into making failure visible and recoverable.
Decisions are written down
Every client application carries a technical document recording what was built and why. Decisions we later reversed are recorded too.
Every platform builds from one branch
All four platforms build from the same core branch. We let it split once, and getting back in step cost us months.
Safety defaults are fail-closed
If a misconfiguration could send traffic outside the tunnel, the client stops. We would rather give no connection than an unsafe one.
