cindy
Cindy is an open-source agent client that wraps existing coding harnesses instead of shipping its own model. The first supported harnesses are Claude Code and Codex, with a native harness in progress. You can switch harness and model mid-task while memory, skills and tools stay continuous, and the README describes splitting one task so it is planned, executed in parallel and reviewed by agents on different harness and model combinations.
It runs locally on your machine with your real files and logged-in apps, can drive the browser, the computer and a phone, and can take work from IM and schedules. MCP connects internal tools. Models can come from the paid Cindy service, a Claude Code or Codex plan you already pay for, your own API keys, or local models.
This repository is the client only: an Electron desktop app and an Expo mobile app in a pnpm monorepo, under Apache-2.0. The backend service lives in a separate repository, and choosing Skip Sign-In gives local agents only, without server-backed features. A plugin marketplace and team skill sharing are listed as in progress.
