Codex++

A tweak system for the Codex desktop app. Inject custom features, fix UI bugs, and add a tweak manager — without rebuilding the app.

Status: ~~alpha~~ Beta! Confirmed working on both macOS & Windows. Expect bugs, especially around auto-updating and new Codex updates. PRs welcome.

What it does

codex-plusplus patches your local Codex.app installation so a small loader runs on startup. The loader pulls a runtime from your user directory, which discovers and loads tweaks (small ESM modules with a manifest + start/stop lifecycle). The runtime injects a "Tweaks" tab into Codex's settings UI so you can enable, disable, and configure tweaks in-app.

Everything beyond the one-time install patch lives outside the app bundle, so iterating on tweaks is just save-and-reload.
