Herding multiple Codex CLI accounts through one local gateway

What it does

CodexManager is a Rust-based desktop app and background service that corrals multiple Codex CLI accounts into a single local gateway. It tracks usage across standard and bonus quota windows, lets you import accounts in bulk—even via ChatGPT session JSON—and generates platform keys with per-model bindings and tier controls. Requests from Codex CLI, Claude Code, or Gemini CLI are forwarded through a local OpenAI-compatible endpoint.

The interesting bit

The author openly admits the codebase is 98% AI-generated (mostly by Codex itself), yet it has accumulated over 2,700 stars and a surprisingly thorough feature set, including a plugin center with Rhai scripting and an experimental WebSocket upstream mode. It also auto-injects image generation tools to mimic official Codex behavior, which is a nice touch for compatibility.

Key highlights

• Local OpenAI-compatible gateway for Codex CLI, Claude Code, Gemini CLI, and third-party tools
• Account pool management with ban detection, grouping, tags, and usage tracking across standard and bonus quota windows
• Platform key generation with per-model bindings, reasoning tiers, and service levels (Fast/Flex/follow request)
• Plugin center supporting curated, enterprise, and custom market modes with Rhai integration
• Can import ChatGPT /api/auth/session JSON directly without a Codex login

Caveats

• The author explicitly states only the Windows desktop build is personally verified; macOS and Linux rely on community testing
• The project carries prominent disclaimers that it is for “learning and development” only and must not be used to bypass rate limits or violate platform terms
• Roughly 98% of the code is AI-generated, which may explain the architectural ambition but also the testing gaps

Verdict

Worth a look if you juggle multiple Codex accounts and want a local traffic cop with a web UI. Skip it if you need a battle-tested, cross-platform guarantee or a simple single-account setup.
