Alternatives
Grass alternatives
Grass currently presents a persistent GrassVM workflow: dispatch Claude Code or OpenCode work from an iPhone, let the agent keep running on the VM, then review diffs and permission requests from mobile. If you would rather keep the repository and coding session in your existing local environment, here are the alternatives worth knowing.

Why developers look for Grass alternatives
- You want to use the repository and toolchain already on your own computer instead of a persistent cloud VM.
- You need Android as well as iPhone support.
- You use Codex, Cursor, Pi, OMP, or Hermes in addition to Claude Code or OpenCode.
- You want a documented encryption boundary between the phone and a local Bridge.
- You prefer your established local development environment over a provisioned cloud machine.
Sesori
Sesori connects native iOS and Android apps to the coding environment already running on your computer through a local Bridge. It supports all seven named assistants.
- Native iOS and Android apps.
- Ordinary session payloads between the phone and Bridge are end-to-end encrypted.
