MultiManager

A unified multi-account/profile manager for Claude Desktop, Claude Code, and Codex — all in one local web UI.

Manage profiles, presets, scenes, MCP servers, plugins, skill sync, backups, and data migration between instances without touching config files manually.

Features

Tab	What it does
Claude Desktop	Save/switch/delete profiles per Claude Desktop instance; auto-backup on switch
Claude Code	Manage presets with environment variables (API keys, models, base URLs); inline env editor
Codex	Save/switch/delete Codex profiles; manage custom OpenAI-compatible endpoints
Scenes	Apply a combo of CD + CC + Codex profiles in one click
Skills	Scan skill directories, sync SKILL.md between master and target roots, diff viewer
Codex endpoint	Set a custom OPENAI_BASE_URL and generate a wrapper script
MCP	View all MCP servers from all tools; add/edit/delete/toggle
Plugins	View and toggle Claude Code and Codex plugins
Settings	Auto-backup toggle, manual backup/restore, quick-launch alias generator, Claude Desktop data sync (IndexedDB copy between instances)

Quick Start

python3 app.py

Then open the URL printed in the terminal (usually http://127.0.0.1:5xxxx/).

The UI will open automatically in your default browser on first run.

.app Bundle (macOS)

A MultiManager.app bundle is included. Double-click it to launch without opening Terminal.

Requirements

• Python 3.11+ (uses tomllib from stdlib for Codex TOML parsing)
• macOS (paths are hardcoded for ~/Library/Application Support/Claude*, ~/.claude/, ~/.codex/)
• Claude Desktop / Claude Code / Codex installed (optional — app works with whatever is present)

How It Works

• Config is stored in ~/.multimanager/config.json (separate from tool configs)
• Backups go to ~/.multimanager/backups/
• The app runs a local HTTP server bound to 127.0.0.1 on a random free port
• All editing is done directly on the tool's config files (JSON or TOML)
• Claude Desktop skills are synced via file copy; other tools can use symlinks

Security

• The app server only listens on 127.0.0.1 (localhost)
• No telemetry, no network calls except localhost
• Credentials stay in your existing config files (no copies stored by MultiManager)
