About
Orbit Rust SDK
A complete Rust rewrite of OpenCode — the open-source AI coding agent.
We're rebuilding OpenCode from the ground up in 100% Rust for better performance, lower memory footprint, and a truly native experience.
> Note: This is the open-source backend SDK derived from OpenCode. Orbit (our Unified Development Environment) is a separate, proprietary product that uses this SDK.
Why Rust?
| Aspect | TypeScript/Bun | Rust | |--------|----------------|------| | Memory | ~200-500MB runtime | ~20-50MB | | Startup | 1-3 seconds | /CONVERSION.md` for the TypeScript → Rust mapping
- Follow the patterns in
docs/workflow/Workflow.md - Test with

Acknowledgments
Special thanks to OpenCode and Anomaly (SST) for building the original open-source AI coding agent.
OpenCode proved that a fully open-source, provider-agnostic AI agent could rival proprietary solutions. We're taking their excellent work and rebuilding it in Rust to push performance even further.
