Comparison
G-Rump vs OpenHands
OpenHands (formerly OpenDevin) is an MIT-licensed agentic platform that runs agents in sandboxed Docker environments behind a web UI, with serious research energy behind it. G-Rump is also MIT — but it's a 13 MB native Mac app that runs on your machine directly, with explicit approval gates instead of a sandbox.
Written by the G-Rump side, so read accordingly — but every row below is checkable, and the “choose OpenHands” list is real advice.
| Aspect | G-Rump | OpenHands |
|---|---|---|
| Runs as | native macOS app | web UI + Docker sandbox (or cloud) |
| License | MIT | MIT |
| Isolation model | your machine, gated: exec approvals + fail-closed checks | sandboxed containers — stronger isolation |
| Setup | unzip, add a key (or Ollama), go | Docker (or their cloud) |
| Footprint | ~13 MB, no Electron, no containers | container images, browser UI |
| Memory | three-tier cross-session memory built in (experimental) | per-task context; microagents for repo knowledge |
| Autonomy | opt-in daemon, scratch branches, never pushes | designed for long autonomous runs in the sandbox |
Choose OpenHands if…
- You want hard isolation — the agent literally cannot touch your machine.
- You want long, hands-off autonomous runs, or a hosted cloud option.
- You work outside macOS.
Choose G-Rump if…
- You want the agent working on your real machine and real toolchain — Xcode, simulators, Keychain — with gates instead of walls.
- You want a instant-start native app instead of a Docker stack.
- You want cross-session memory of you and your projects.
The grumpy verdict
Different isolation philosophies: OpenHands sandboxes the agent away from your machine; G-Rump gates the agent on your machine because the machine is the point — your simulators, your tools, your projects. Pick the philosophy that matches your risk tolerance.
