cindy: A Local AI Agent That Unifies Claude Code and Codex

Cindy is an open-source AI agent that runs locally and directly handles real files and logged-in apps. It supports Claude Code and Codex as default harnesses, with native harnesses planned for future addition. It is ready to use immediately after installation, allowing you to perform real project work without complex setup.

You can freely combine harnesses and models, and switch between them even during a task. In doing so, workspace, memory, skills, and tool state are maintained continuously. It also supports workflows where agents with different harness-model combinations plan, execute in parallel, and review a single task. It provides browser, computer, and smartphone control, as well as integration with IM and calendar.

Memory is applied identically across all harnesses after a single modification, and skills can be reused anywhere once learned. Repetitive tasks are automatically scheduled, executed, and reported. You can connect internal tools and business systems via MCP, and extend features and UI through plugins.

It is structured as a pnpm monorepo containing an Electron-based desktop app and a React Native-based mobile app. It is released under the Apache-2.0 license, and models can be connected in various ways, including official cloud services, existing subscription accounts, your own API keys, and local models.
