Claude Code and Codex, side by side in VS Code

Claudex runs the agents you already use beside your code, so you can plan with one, build with the other, and review every change in the editor you know.

  • Run Claude Code and Codex together

    Open threads with either agent, pick the model per chat, and keep both working in one panel next to your code.

  • Hand off work with full context

    Continue a thread with the other agent. A context chip shows exactly what carries over before you send.

  • Turn a plan into code

    Ask for a Markdown plan, edit it, then click Implement plan. The agent builds from your latest version.

  • Approve commands, review every diff

    Answer approval requests with Allow once or Decline, then open each changed file in VS Code's diff editor.

  • One Git worktree per task

    Optionally start a task in its own worktree so parallel agents never step on each other's changes.

  • Your logins, skills and MCP servers

    Uses your installed CLIs with their own sign-in, skills and MCP config. No API keys, no backend, no telemetry.

Free forever

No tiers, no trials, no account. Claudex runs on the Claude Code and Codex logins you already have, so your existing plans cover the agents.

Frequently asked questions

Is Claudex free?

Yes. The Claudex extension is free and MIT-licensed. Claude Code and Codex usage follows your own provider plan and its usage limits.

Do I need an API key?

No. Claudex runs your installed Claude Code and Codex CLIs, which keep their own sign-in. If you're logged in on the command line, you're ready.

Does my code go to a Claudex server?

No. There is no Claudex backend, telemetry or credential store. Conversations are saved locally in VS Code's workspace storage, and each agent talks to its provider exactly as it does in your terminal.

Can I switch from Claude Code to Codex in the middle of a task?

Yes. Choose the other agent from the model menu, check the “Context from …” chip to see what carries over, and continue the same thread.

Does it use my existing skills and MCP servers?

Yes. Claudex uses your installed agents' skills and MCP configuration, and supports separate profiles for additional accounts.

Which platforms are supported?

Claudex needs VS Code 1.96 or newer. It is developed and tested on macOS; Windows, Linux and remote workspaces have not been validated yet.

Put both agents to work

Free in the VS Code Marketplace. Uses your existing logins.
