Claude Tandem
Claude Tandem is a macOS menu-bar app that runs multiple Claude accounts side by side and hands projects between them.
Claude Tandem is a native macOS menu-bar application designed to manage multiple Claude accounts and Claude Code profiles simultaneously. It allows users to run different subscriptions, such as personal and work accounts, side by side on the same Mac using APFS clones and separate Keychain logins while sharing settings, skills, and plugins. The app tracks projects, memory, and files across machines and accounts. It features handoff capabilities to transfer project definitions, memory snapshots, and byte-verified files between Macs and accounts using a shared drive like iCloud. Users can initiate handoffs via terminal commands or the native app interface, utilizing the /handoff skill to generate briefs and ownership logs to prevent simultaneous edits.
