Codex++: a Rust manager that wraps Codex in extensions and routes 50+ coding agents through one local gateway

Everything is an extension, including the requests sent to the model

Codex++ describes itself as a unified manager for AI coding agents built on an everything-is-an-extension architecture. Extensions can take over the interface, commands, the tools a model can call, hooks in the agent loop, and the requests sent to the model and the replies that come back. You do not have to write one by hand: in a Codex conversation you describe the change, for example turning the send button into a dog head, and the agent writes the extension, hot reloads it and takes a screenshot to confirm. A single page lists curated extensions that have been reviewed, community extensions from GitHub, your own local extensions and imported dsh plugins, with one-click publishing for your own.

The consequence is a wide trust surface. An extension that can rewrite model requests and replies can also read them, so a community extension deserves the same scrutiny as any code you run against your source and credentials.

One local gateway shares a provider pool across 50+ agents

The second pillar is a built-in local gateway. Codex, Claude Code, Gemini CLI, OpenCode, Zed, VS Code and more than 50 agents in total can share one provider pool. The gateway chooses a provider by model name and switches to another upstream automatically when a key is cooling down or a provider trips its circuit breaker. It converts between the Anthropic, Chat, Responses and Gemini protocols, so Claude Code can use a provider that speaks a different protocol, with Anthropic requests converted to Chat or Responses inside the gateway. Subscriptions such as ChatGPT, GitHub Copilot, Cursor and, for Grok CLI, SuperGrok can be logged into the pool.

The original direct modes remain: official login, official plus API, pure API, and aggregator provider, and you can switch between gateway and direct at any time. That matters, because the gateway concentrates every key and subscription in one process; if you only need Codex with an API key, direct mode keeps that concentration out of the picture.

It launches the official apps instead of patching them

You double-click to open the management interface and start each application from there. The project states that it does not modify any official application's installation files. For the Codex desktop app it adds session management, interface enhancements, multiple instances, request smoothing, extensions and a desktop pet. For Claude Desktop it offers an enhanced build with a Chinese interface, voice input and Computer Use, and Computer Use plus sub-agent collaboration also reach across agents, including DeepSeek Harness, which can be called as a sub-agent inside a Codex conversation.

Leaving official install files alone means an official update should not be overwritten by Codex++, and removing it leaves the original apps intact. The trade-off is that features only apply when you start the apps through the manager; launching Codex directly gives you the stock app.

A Tauri manager on a Rust workspace

Cargo.toml defines a Rust workspace on edition 2024 with four members: crates/codex-plus-core, crates/codex-plus-data, apps/codex-plus-launcher and apps/codex-plus-manager/src-tauri, the last being the Tauri desktop manager. Workspace dependencies show where the work happens: reqwest with rustls and system proxy support for upstream calls, tokio-tungstenite for WebSocket traffic, rusqlite built with bundled SQLite and backup support for local data, aes-gcm and sha2 for cryptography, and sherpa-onnx, a speech toolkit that fits the voice input feature. The license is AGPL-3.0-only, which matters if you plan to modify the gateway and offer it to others over a network.

There is no install command to copy. Builds are downloaded from the GitHub Releases page of BigPizzaV3/CodexPlusPlus, and issues go through GitHub Issues with your OS, Codex++ version, reproduction steps and redacted logs.

Three releases in two days and a Chinese-first README

Codex++ v2.1.2 and v2.1.3 were both published on 2026-10-29 and v2.1.4 followed on 2026-10-30, while Cargo.toml in the repository already reads 2.2.0. The last push was on 2026-11-02. The pace means fixes arrive quickly, and also that behaviour can shift between builds a day apart; keep the previous installer if a gateway change breaks a working setup.

The main README is written in Chinese, with an English version in README_EN.md, and support channels include a QQ group, a Telegram channel and LINUX DO. The sponsor list is made up of API relay services with referral links. Treat those as advertisements, not endorsements of reliability, and pick any upstream for the provider pool on your own criteria.

Editorial conclusion

Codex++ fits heavy users of Codex and other coding agents who want one place to manage providers, sessions and UI tweaks, and who are comfortable letting extensions and a local gateway sit between their agents and the model. It is a poor fit for anyone who cannot route credentials and full request traffic through third-party software, or who needs English-first documentation and a slow release cadence. Before installing, decide whether you will use gateway mode or keep the direct connection, review any extension's code before enabling it, and check your providers' own terms before logging subscriptions into a shared pool.
