| 71 | ## Why OpenCrabs? |
| 72 | |
| 73 | OpenCrabs runs as a **single binary on your terminal** — no server, no gateway, no infrastructure. It makes direct HTTPS calls to LLM providers from your machine. Nothing else leaves your computer. |
| 74 | |

| 76 | |
| 77 | | | **OpenCrabs** (Rust) | **Node.js Frameworks** (e.g. Open Claw) | |
| 78 | |---|---|---| |
| 79 | | **Binary size** | **34–36 MB** single binary, zero dependencies | **1 GB+** `node_modules` with hundreds of transitive packages | |
| 80 | | **Runtime** | None — runs natively | Requires Node.js runtim |
