cnfgr

Sync your AI agents across every tool and device.

cnfgr is a desktop app that keeps your AI coding configuration — agents, skills, slash commands, MCP servers, and context files — synchronised across every AI coding tool you use (Claude Code, Codex CLI, Gemini CLI, GitHub Copilot, Cursor) and across macOS, Windows, and Linux.

You author your configuration once in cnfgr. The app projects it into the correct on-disk format and location for each installed tool. Changes you make in any tool, on any device, sync back through cnfgr and propagate everywhere else.

Why cnfgr

  • Author once, project everywhere. Write an agent or skill a single time; cnfgr writes it into each tool’s native format and file location for you.
  • Local-first, multi-device sync. Edits apply instantly and work offline. State converges across all your devices with conflict resolution and version history — no clobbering.
  • Your secrets stay yours. API keys and tokens are stripped before anything syncs and re-hydrated only on your own devices. cnfgr never syncs .env files, OAuth tokens, or any authentication state.

How it fits together

cnfgr runs as a small background daemon plus a UI window. The daemon owns all file I/O against your tools’ directories, watches for changes, and maintains a single source of truth that syncs to the cloud and back down to your other devices.
