Cindy

Open source desktop agent that runs Claude Code and Codex harnesses on your own machine

About

One local agent across Claude Code, Codex and any model

Cindy ("Consider it done") is an Apache-2.0 open source agent client from the makecindy team, with Electron desktop and Expo mobile apps in one monorepo. Instead of being another harness, it sits on top of existing ones: Claude Code and Codex are supported today, with more and a native harness on the way. Models and harnesses can be mixed freely and swapped mid-task while workspace, memory, skills and tools stay continuous, and a single task can be planned, executed in parallel and reviewed by agents on different harness and model combinations. It runs locally against your real files and logged-in apps, can drive your browser, computer and phone, and takes work from IM and schedules. Memory is shared across harnesses (correct it once and it sticks), skills are reusable everywhere, MCP connects internal tools, and recurring work can schedule and report on itself. The client is free: sign in to the Cindy service with usage-based billing, plug in the Claude Code or Codex plan you already pay for, bring your own API keys or use local models. Around 3.8K GitHub stars and trending in October 2026.
