# Architecture

OcHub is a Rust workspace built around GPUI and axum.

## Crates

| Crate | Role |
| --- | --- |
| `ochub-core` | Domain model, SQLite storage, provider switching, client config writers, sync, MCP, skills, sessions, usage, and auth |
| `ochub-server` | Loopback control API and in-process relay gateway |
| `ochub-convert` | Request and response conversion between supported API dialects |
| `ochub-app` | Native GPUI desktop application hosting the core and server |

## Platform specifics

GPUI is pinned to a tested Zed commit. Linux builds enable both Wayland and X11;
macOS builds compile Metal shaders at runtime.
