CodexMonitor is a free MIT Tauri desktop command center for OpenAI's Codex CLI: it manages workspaces and threads over the Codex app-server protocol, streams conversations and approvals as they run, meters your account's rate limits and credits, and pairs the agent with git, GitHub, and worktree tooling in one window. **CodexMonitor watched Codex before OpenAI shipped its own desktop app, and it is now dormant: seven months without a commit while the vendor absorbed the same job.** ## What it is A Tauri 2 + React app for macOS, Windows, and Linux (built from source with Node and a Rust toolchain; signed installers and an in-app updater ship through GitHub releases) that spawns one `codex app-server` per workspace and renders its threads. The surface covers workspace and worktree management (agents can run in isolated worktrees under the app data directory), thread pin, rename, archive, and resume, a composer with skills, prompts, reviews, and file-path autocomplete, image attachments, Whisper dictation, model and reasoning-effort pickers, approval handling, and per-workspace settings synced into the Codex config. Around the agent sit git diff and staging controls, branch management, GitHub Issues and Pull Requests through the `gh` CLI, a prompt library, a terminal dock, and a sidebar usage-and-credits meter beside a home usage snapshot. An optional remote daemon mode runs Codex on another machine, with a Tailscale setup runbook and a headless daemon CLI, and an iOS remote-mode client is in progress. Made by Thomas Ricouard (Dimillian), an independent developer, under MIT; the site states the app is not affiliated with OpenAI. ## Status Dormant: 4,348 stars, 415 forks, 94 open issues, created 2026-01-11, last commit 2026-03-26, latest release v0.7.64 on 2026-03-22 (a 0.7.68 version bump landed in the repository three days later and was never released), as of 2026-10-23. Star History Chart It launched in January 2026 as "an app to monitor the (Codex) situation" and became the main third-party Codex GUI within weeks, drawing a public retraction from Theo of t3.gg, who dropped plans to build his own after using it. When OpenAI's own Codex desktop app appeared, Hacker News commenters called the two near-indistinguishable twins, with one crediting CodexMonitor's feature list first and another answering that every surface in this category looks alike; the repository's last commit landed days after that comparison. **Its ending is the finding: a 4,000-star third-party command center went quiet within two months of the vendor shipping the same surface, and its 94 open issues are still waiting.** ## Strengths - The most complete third-party Codex surface shipped to date: worktrees, approvals, plans, dictation, GitHub integration, and remote daemon mode in one MIT codebase. - Genuine popularity for a single-maintainer desktop app: 4,348 stars, 415 forks, and public testimonials, including a retraction from a would-be competitor. - It provably influenced the category: the vendor's own app arrived looking, by Hacker News commenters' account, like its twin. - Local-first: it drives your own Codex CLI login and config, and remote mode rides your own Tailscale tailnet with a token you issue. ## Cautions - Seven months dormant as of 2026-10-23, while the Codex CLI and the app-server protocol it drives keep moving, so expect drift between the app and the harness. - OpenAI's desktop app now covers the same ground with vendor support, which weakens the case for adopting an unmaintained alternative. - iOS support is unfinished (terminal and dictation unavailable on mobile builds), and building from source needs a Rust toolchain plus CMake and, on Windows, LLVM. - It meters the account but does not analyze history: no transcript search, no cross-session archive, and no cost reports over past sessions. ## Pricing Free and open source under MIT. The site still carries its beta disclaimer (provided as is during the beta period), and no paid tier has ever been published. ## Compared to - [Claude Code Agent Monitor](../claude-code-agent-monitor/index.md): the multi-harness live control room, still shipping; CodexMonitor is Codex-only and dormant, but adds worktree orchestration and GitHub panels the Monitor lacks. - [Codex](../../harnesses/codex/index.md): the vendor's harness and, since 2026, its own desktop app, the default choice now that the independent alternative is quiet. - [Tokscale](../tokscale/index.md) and [ccusage](../ccusage/index.md): usage reporting without agent control; CodexMonitor meters the account in its sidebar but cannot answer history questions the way they do. ## Bottom line **Recommended only if you live in Codex, want every control in one native window, and accept an unmaintained codebase; otherwise the vendor's app or an active control room is the safer pick.** Its dormancy is the data point: vendor surfaces absorb third-party command centers quickly. ## Changes - 2026-10-23 - Created from the coordinator's entrant handoff, admitted as the category's first dormant member, the monitor kind beside ccusage and tokscale, with the official-app comparison from its Hacker News thread recorded. ## See also - [Claude Code Agent Monitor](../claude-code-agent-monitor/index.md) - the active multi-harness counterpart with launch-and-resume control - [Codex](../../harnesses/codex/index.md) - the harness and vendor app CodexMonitor drives and competes with - [Tokscale](../tokscale/index.md) - the ledger-style usage reporting CodexMonitor's sidebar meter only gestures at - [Session Analytics Feature Matrix](../session-analytics-feature-matrix/index.md) - the category comparison this note joins ## References - https://api.github.com/repos/dimillian/codexmonitor - the repository, 4,348 stars, MIT, created 2026-01-11, last pushed 2026-03-26 (as of 2026-10-23) - https://raw.githubusercontent.com/Dimillian/CodexMonitor/main/README.md - the feature set: workspaces, threads, composer, git and GitHub panels, daemon and iOS paths - https://www.codexmonitor.app - the positioning ("monitor your Codex situation"), the testimonials, and the beta disclaimer - https://api.github.com/repos/Dimillian/CodexMonitor/releases - the release line through v0.7.64 (2026-03-22), the signed installers, and the updater feed - https://api.github.com/repos/Dimillian/CodexMonitor/commits?per_page=5 - the last commits, ending 2026-03-26 - https://news.ycombinator.com/item?id=46859808 - the thread calling CodexMonitor and the official Codex app near-indistinguishable twins
