v1.1.0 Now with Codex Latest
Latest

Adds Codex desktop app support alongside Claude. Each Codex profile runs as a genuinely concurrent instance via the undocumented CODEX_ELECTRON_USER_DATA_PATH env var that bypasses Codex's singleton check — no admin, no registry hacks. See README for the technical details.

What's new

  • Codex support — full feature parity with Claude (profiles, shortcuts, login patch, etc.)
  • App switcher — press 8 in the menu to flip between Claude and Codex
  • Real concurrent Codex instances — multiple profiles run side by side, each signed into its own OpenAI account
  • Per-app isolation: profiles, shortcuts, codex:// / claude:// login patches, all independent
  • State consolidated into a single state.json (replaces .active_profile)

Install

Same as before — download claude-multi-instance-v1.1.0-windows.zip below, unzip both .exe files in the same folder, and run claude-multi-instance.exe.

From source: clone the repo, python main.py (Python 3.9+, no dependencies).

Requirements

  • Windows 10 or later
  • Claude and/or Codex desktop installed

  • Auto-created desktop shortcuts (toggleable per profile)
  • Multi-select for batch actions (launch / close / delete)
  • Close running sessions via process tree kill
  • Optional claude:// handler patch to route Google login callbacks to the last-launched profile

Install

Option 1 — Pre-built binary (no Python required)
Download claude-multi-instance-v1.0.0-windows.zip below, unzip both .exe files in the same folder, and run claude-multi-instance.exe.

Option 2 — From source
