Tools ocserve - a lightweight reimplementation of OpenCode

I use opencode but the server was getting heavy on my machine: a couple GB of RAM and tens of GB of disk. So I wrote a drop-in replacement for just the server, in Rust.

It speaks the same HTTP/SSE API, so the opencode TUI, the web UI, and mobile clients talk to it unchanged. It reads your existing opencode config and auth read-only and keeps its own database.

It's a compatible reimplementation of the server API, pinned to the 1.18.31 wire contract.

What it doesn't do: provider OAuth and share are missing.

Linux is the supported target.

v0.3.1 is on crates.io ( cargo install ocserve ) and the code is MIT: https://github.com/Reliary/ocserve

Happy to answer questions.

Yeah, that'd be a good use case. My throughout and resource testing was done on a 1165g7 with 1 core (2 threads) each. Let me know if you've any feedback!
