Cindy is an open-source AI agent that works out of the box. She brings multiple harnesses, models and tools into one agent that finishes real work in your projects and apps. Ready from day one, yours to shape over time.
Cindy runs locally on your own machine, using your real files and logged-in apps. The first supported harnesses are Claude Code and Codex — more are being added, and a native harness is in the works. Models and harnesses mix freely and can switch mid-task while your workspace, memory, skills and tools stay continuous; one task can even be planned, executed in parallel, and reviewed by agents on different harness × model combos. She can drive your browser, computer and phone, and take work from IM and schedules.
This repository is the open-source client for Cindy — the desktop and mobile apps plus their shared packages, organized as a pnpm monorepo.
The client is free to use, and its source code is open under Apache-2.0. Bring models your way: sign in to the official Cindy service (usage deducted transparently), authorize the Claude Code / Codex Coding Plan you already pay for and keep using it inside Cindy — no duplicate bill — connect your own API keys, or use local models. See cindy.app for service details, pricing, and downloads.
Yours to shape
Open source means more than visible — it means changeable:
- Memory — correct her once and she does it right from then on, shared across harnesses.
- Skills — teach a way of working once and reuse it everywhere; handing them to your team is in the making.
- Automation — recurring work schedules itself, runs itself, reports back.
- MCP — wire your internal tools and business systems into her reach.
- Plugins — reshape features, UI and interactions, shared through an open marketplace (in the making).
- Source — audit, fork, extend, and contribute improvements back under Apache-2.0.

What's in this repo
| Path | Description |
|---|---|
apps/desktop | Electron desktop client |
apps/mobile | Expo / React Native mobile client |
packages/* | Shared client capabilities (auth, device-link, agent orchestration, model providers, …) |
apps/*-bin | Tool binaries shipped with the desktop app; none are committed — claude-code, codex, and ripgrep are downloaded per platform by pnpm install, and the Android platform-tools binaries are fetched (pinned version, sha256-verified) before Windows packaging |
Not in this repo: the backend service lives in a separate repository and is not part of this monorepo.
| Mode | Account requirement | Availability |
|---|---|---|
| Hosted service | Cindy cloud account | Use Cindy's full hosted service. See pricing. |
| Skip Sign-In | No Cindy sign-in required | Choose “Skip Sign-In” on the login screen to use local agents; the app then shows the account state as “Not signed in”. Server-backed capabilities are unavailable in this state. |
Prerequisites
- Node.js 22.x
- pnpm 10.x (v11 is not yet supported)
- Git LFS
Getting started
Contributor setup, Git LFS, dependency updates, and access requirements are maintained in
CONTRIBUTING.en.md.
Plugins are installed through SkillHub or manually.
Minimal entry point:
git clone https://github.com/makecindy/cindy.git
cd cindy
git lfs pull
pnpm install
Development entry points
# Mainland China Cindy account
pnpm restart:desktop:remote --region=cn
# Global Cindy account
pnpm restart:desktop:remote --region=global
Remote development uses your own Cindy cloud account and existing login state, so
you can continue existing sessions and work while developing the client. Use cn
for Mainland China accounts and global for everyone else; do not rely
on the internal default. Full desktop, mobile, data-isolation, and validation
workflows are in CONTRIBUTING.en.md.
“Skip Sign-In” on the login screen runs local agents without a Cindy account (shown in the app as “Not signed in”), not a connection to a local server. Server-backed capabilities are unavailable in this state.
About the default servers: the client connects to Cindy's official cloud
services by default (endpoint manifests in
config/endpoint.json and
config/endpoint.global.json; desktop
auto-updates also come from the official CDN). This is intentional — external
developers don't need to self-host a server: sign in with your own Cindy
account in a dev build and develop / test directly against the official
servers.

Contributing
Contributions go through pull requests into main. Read
CONTRIBUTING.en.md first, then use
.github/PULL_REQUEST_TEMPLATE.md.
Every commit needs a Developer Certificate of Origin sign-off
(git commit -s); a DCO check on each pull request enforces it, and no CLA is
required.
Please also follow CODE_OF_CONDUCT.en.md. For ordinary
usage questions, see SUPPORT.en.md; report security issues
privately through SECURITY.en.md.
Security
Never commit credentials or authorization files to the working tree. If you
discover a security issue, follow SECURITY.en.md to report it
privately rather than opening a public issue.
Privacy & telemetry
Official distribution builds include TapDB usage analytics for product-level aggregate statistics (device / OS / app-version metadata; associated with your account ID after sign-in). It does not collect chat content, file content, or working-directory data. In addition, while signed in to a cloud account the client sends an online heartbeat to Cindy services (account ID, platform, and version only). Crash dumps stay on the local machine and are never uploaded automatically.
Building from source? You are not required to keep analytics:
- Mobile is off by default — without TapDB credentials (
clientId/clientToken) injected at build time,apps/mobile/src/analytics/mobileTapdb.tsis a no-op; - Desktop can be fully stripped by removing the
initTapdb()call inapps/desktop/src/renderer/index.tsx(implementation lives inapps/desktop/src/renderer/analytics/).
