CodexMonitor

CodexMonitor (GitHub: Dimillian/CodexMonitor) is an open-source Tauri desktop command center for orchestrating multiple OpenAI Codex agents across local workspaces. It is not a simple token-cost menu-bar widget, and it is not the official ChatGPT or Codex desktop app from OpenAI. Created by Thomas Ricouard (Dimillian), best known for Ice Cubes, the app speaks Codex's app-server protocol, spawns one Codex app-server per workspace, and gives you a unified UI for threads, diffs, git worktrees, GitHub Issues and pull requests via the gh CLI, model and reasoning-effort controls, Whisper dictation, a multi-tab terminal dock, usage and credits metering, and optional remote daemon access over TCP with Tailscale helpers. The product exists because serious Codex users outgrow a single terminal pane. Once you run several agents on several repos, you need a sidebar of workspaces, durable thread history (start, resume, pin, rename, archive), isolated git worktrees so feature agents do not thrash your main checkout, and first-class review surfaces for diffs and PR comments. CodexMonitor is built for that workflow: add projects, group and sort them, queue composer prompts with images and $skills /prompts @files autocomplete, approve tool use, and keep an eye on account rate limits from the sidebar usage meter. Licensing and cost: the app itself is free and open source (MIT). You must have the Codex CLI (codex on PATH) plus a ChatGPT or OpenAI account that can run Codex. Model and subscription costs are OpenAI's; CodexMonitor does not sell inference. Platforms: native Tauri builds for macOS, Windows, and Linux. An iOS remote client for desktop-hosted backends was work-in-progress; treat mobile as unfinished. Maintenance status (important): development was extremely active in February-March 2026, with roughly ten releases from v0.7.58 through v0.7.67 shipping features such as the multi-tab terminal dock, sidebar usage and credits meter, in-app updates, Tailscale-assisted remote backend setup, and a refactored tray menu. Commit and release activity then paused around late March 2026. As of mid-2026 the repository remains public and unarchived, community stars sit around 4,200+, and the app still works for many users, but you should adopt it knowing maintenance has paused, open issues may linger, and future Codex CLI or app-server protocol changes could require a fork or volunteer maintainership under the MIT license. Competitive framing: OpenAI's official ChatGPT/Codex desktop surface is the closed-source, vendor-supported path. Conductor is a Mac-native multi-agent orchestrator that also runs Claude Code and Cursor agents in worktrees and has paid cloud tiers. CodexMonitor stays Codex-only, cross-platform, and fully open source. Choose CodexMonitor when you want a free, transparent Codex command center and can accept single-maintainer / paused-release risk. Choose the official app when you want OpenAI support guarantees. Choose Conductor when you need multi-agent brand coverage or cloud sandboxes. Operationally, Mac Apple Silicon machines with 16GB+ RAM handle several concurrent Codex workspaces comfortably; keep gh authenticated for GitHub panels, keep Codex CLI current enough for the app-server protocol CodexMonitor expects, and prefer worktree agents for risky refactors so main stays clean. Remote daemon mode helps when you want a capable desktop host and a thinner client elsewhere, but networking and Tailscale setup are your responsibility. Dictation via Whisper is useful for long prompts; treat experimental surfaces as such. Practical take: CodexMonitor is a real Codex orchestration desktop app with early adoption around 4,200+ GitHub stars and a clear pause in upstream maintenance after late March 2026. Install it when you need a local control plane for Codex across workspaces. Do not treat it as a token-cost menu-bar gadget, and do not expect OpenAI-level product support from a paused MIT project.
