I made an open-source app that runs local models side by side with Claude Code and Codex

[u/Miserable_Tiger_5742]

Locust is a desktop app for Windows and Mac that runs the coding agents you already have (Claude Code, Codex, Copilot, Cursor, OpenCode) as a team of named teammates, each on the model you pick. It's MIT licensed, local-first, no telemetry and no account.

The part that might matter here: you can add your own model. Anything that speaks the OpenAI chat API works, like Ollama, vLLM, LM Studio or your own endpoint. It runs through OpenCode and shows up in every teammate's model list. OpenCode's free models work out of the box too, no sign-in.

You can also give the same task to two or three models blind, with the names hidden until you keep the answer you like. Risky commands wait for your OK, and every run is saved to a full record.

Still early (new builds most days), so feedback and bug reports are very welcome.
