A control panel for the mess Codex leaves in ~/.codex

What it does

Codex keeps accounts, sessions, MCP entries, Skills, and router settings spread across TOML, JSON, and SQLite files under ~/.codex. AiMaMi is a native desktop app (Tauri 2, React, Rust) that reads and writes all of that locally: account switching, quota monitoring with automatic fallback when the 5-hour or weekly limit hits, session inspection and bulk cleanup, MCP/Skills management, and config repair.

The interesting bit

The smart router forwards relay/third-party models through AiMaMi’s own local proxy, so you can use them inside Codex Desktop while keeping historical threads resumable. The catch: AiMaMi has to keep running for relay models to work. It also touches only its own managed block in AGENTS.md, with preview and rollback — a nice bit of restraint for a tool that edits your files.

Key highlights

• Auto-switch accounts on quota exhaustion, with Codex restart
• Session management against the real local index, including bulk cleaning
• Relay provider setup, connectivity tests, and router diagnostics
• System maintenance: diagnose, rebuild registry, force-quit Codex, fix common config issues
• macOS notch and tray quota display; English and Chinese UIs

Caveats

• Linux support is explicitly “best-effort” for some workflows only
• Relay traffic depends on a third-party proxy staying alive — a new moving part in your setup
• Not affiliated with OpenAI; relay usage is at your own risk per the disclaimer

Verdict

Worth a look if you juggle multiple Codex accounts or relay providers and are tired of editing auth.json by hand. If you’re a single-account, straight-from-OpenAI user, most of this is solving problems you don’t have.
