Overview

  • VS Code sidebar for switching between the Claude Code and Codex subscription accounts you own (Claude Pro / Max, ChatGPT Plus / Pro) without signing out and back in.
  • Each account lives in its own config directory, so its sign-in, settings, and history stay intact.
  • Built for VS Code WSL remote windows, with an English and Simplified Chinese UI.

Common Uses

  • Move to another subscription when one account hits its usage limit.
  • Keep work and personal Claude Code or Codex accounts separate on one machine.
  • Maintain one copy of global CLAUDE.md / AGENTS.md rules across every account.

Requirements

  • VS Code or a VS Code-based editor such as Antigravity IDE, version 1.107 or later, used through a WSL remote window. Native Windows and macOS are not supported.
  • The official Claude Code and/or Codex extensions installed on the WSL side.
  • For Codex switching: bash as the login shell.

FAQ

Frequently asked questions and troubleshooting guides.

No. For Claude it only checks whether `.credentials.json` exists. For Codex it decodes the ID token payload in `auth.json` locally to show the email and plan, and never copies, swaps, rewrites, logs, or sends tokens.
Codex reads its account only at startup, so PlanSwap restarts the WSL server after a confirmation. Every WSL window disconnects and needs one Reload Window click, and integrated terminals close.
No. PlanSwap is WSL/Linux only and is built for VS Code WSL remote windows.
