CodexHost alternatives
TL;DR
CodexHost is a free, LGPL-3.0 add-on that injects Claude Code, Pi, OpenCode, Grok and more than a dozen other agents into OpenAI's Codex Desktop, so they share its chat, diff review and worktrees. People look elsewhere because it patches a closed app it doesn't control, so Codex updates have repeatedly broken it; because it only runs agents with an adapter, shown as chat instead of their own terminal UI; and because it doesn't support WSL. Pane is the closest independent alternative: Codex, Claude Code, Pi and any other CLI agent side by side, each in its real terminal and worktree, with diffs and git built in, on Windows, inside WSL, macOS and Linux. T3 Code, Paseo and MonoCode are the picks if you want a chat view across agents.
the alternatives
Every tool here runs Codex and other agents side by side in one app, without depending on Codex Desktop. The chips show where each one runs: green is native, amber has a catch, red is no.
1.Pane
Best for every CLI agent in its real terminal, Codex included.
Codex, Claude Code and Cursor are one click; Pi, Oh My Pi, OpenCode, Grok and any other CLI run as custom commands. Each pane has its own worktree, a Changes panel and git shortcuts, and an orchestrator chat can hand work between agents. Free, AGPL-3.0, no account.

2.T3 Code
Best for a polished chat view over Codex, Claude Code, Pi and more.
MIT, with phone apps and usage tracking across providers. Runs a fixed list of agents plus ACP Registry agents. Young at version 0.1.x.
WindowsWSLmacOSLinux
3.Paseo
Best for Pi and Oh My Pi built in, with phone apps.
Apache-2.0 daemon with desktop, phone, web and CLI clients; agents can delegate to each other. Agents couldn't run in a WSL repo from the Windows app in our test.

4.MonoCode
Best for a light chat GUI with tabs for each agent.
MIT, runs Claude Code, Codex, Cursor, Grok, OpenCode, Antigravity, Pi, omp, Hermes and Devin from their logged-in CLIs. Very early, and no WSL support.

5.Orca
Best for an all-in-one app for 40 agents.
MIT, real terminals in worktrees, a browser, issue trackers and a phone app. Runs agents inside WSL. Heavy at about 1 GB installed.

why people look for a codexhost alternative
It lives inside someone else's app.
CodexHost attaches to Codex Desktop through its debugging port and hooks private, minified objects in its interface. When Codex updates, things break: sessions have vanished from the sidebar, agent menus stopped working, and every external agent's connection check has failed until a CodexHost hotfix shipped. The project keeps a separate playbook just for diagnosing Codex upgrades, and it's unofficial, with no endorsement from OpenAI.
It only runs agents it has an adapter for, so Gemini CLI, Amp, Aider and Goose are out, and the ones it does run lose their own terminal UI and keybindings. There's no supported WSL path: the maintainer's advice is to install agents on the Windows side. The Windows executables are unsigned and have been quarantined by Defender, and the macOS app isn't notarized.
moving from codexhost to pane
Keep Codex and add any agent next to it, each in its own terminal and worktree.
Your agents keep their own logins, and nothing depends on Codex Desktop. Open your repository in Pane and create a pane per task: each gets its own worktree and branch by default. Start Codex, Claude Code or Cursor with a click, and add Pi, Oh My Pi, OpenCode, Grok or anything else as a custom command; they run in their own terminal UI, exactly as they do in a shell.
Review in the Changes panel, where every file opens as a diff tab, and commit, push and merge with shortcuts. For the "hand this to Claude" habit, Pane's orchestrator, Sessions, can start an agent in another pane, send it the task and read back its result. If your code lives in WSL, Pane runs the agents, terminals and git inside the distro.
our verdict
CodexHost is a clever way to bring other agents into Codex Desktop, but it's only as stable as Codex's next update. If you want Codex, Claude Code, Pi and the rest side by side on your own terms, Pane is the most direct alternative and the one that also handles WSL. For a chat view across agents, T3 Code or Paseo.
how we checked
On October 4, 2026 we installed CodexHost 0.12.1 on Windows 11 and ran its launcher, CLI and web console; we didn't sign in to Codex Desktop, so its in-app behaviour comes from CodexHost's docs, release notes and issues. Pane, T3 Code, Paseo and Orca ran on the same PC with WSL2 (Ubuntu 24.04). MonoCode's facts come from its README, changelog and source.
Facts about each product come from its own docs, release notes, issue tracker and source code, checked on October 3 and 4, 2026.
- What we ran
- → Pane 2.4.155 on Windows 11, native and WSL2 (Ubuntu 24.04) repos
- → CodexHost 0.12.1 launcher, CLI and console on the same PC, October 4, 2026
- Who wrote this
- We make Pane, so we have a stake in this. We tried to be fair: CodexHost's strengths are listed as plainly as Pane's, every claim was checked against the product itself or its docs and source, and the screenshots are unedited captures from our own runs.
