Cindy is an open-source AI agent, ready out of the box and yours to shape. Connect your computers and phone, bring the models and subscriptions you already use, and build a companion that knows how you like to work.

All your devices. One Cindy.

Your work computer, home desktop, laptop and phone belong together.

• Pick up the same work. Open a session from another device, continue the conversation, and access its files without copying everything into a new chat.
• Share more than a screen. Use model providers configured on another computer — including supported subscriptions, API providers and local models.
• Reach your whole desktop. Built-in remote desktop on your phone lets you open apps, type and operate a connected computer when a chat isn't enough.

Your computer becomes your server: no server rental or self-hosting setup.

How connections and data work

For remote access to your computers, keep them online, sign in with the same account and enable the relevant permissions. Model sharing requires allowing remote access to that provider; remote desktop also needs its own permissions. Project files stay on their computer — remote access is not whole-disk sync. Cloud companions sync their conversations, memory, skills and shared attachments through Cindy's services; model providers process the requests sent to them. Provider and service billing still apply.

Keep your favorite agents. Get a better way to work.

Already using Claude Code or Codex? Cindy brings them together with Pi, then adds a shared interface, multi-device access, tools and a companion of your own.

Harness	What it brings
Claude Code	Claude Code's agent workflow, with Cindy's interface and connected tools.
Codex	Codex's coding workflow, available alongside your other agents.
Pi	A lean, open-source, extensible agent with support for multiple model providers.

Choose a supported harness and model combination, and change it as the work evolves. Your session stays in Cindy; switching harnesses hands off or rebuilds the engine context rather than making their internal states identical.

One agent not enough? Let her lead a team. Use different agents for planning, parallel implementation and independent review, with a shared goal and clear acceptance criteria.

Real work, in your actual tools

Work with your files, browser and apps. Ask for a change, inspect what happened, and keep working from the result. Answers can include charts, interactive controls and rich HTML, not just a wall of text.

Build a recurring routine with automations, or hand over work through connected chat channels such as Slack and Telegram. Connect more tools through Skills, plugins and MCP.

Ready from day one. Yours to shape over time.

• Create your own companions. Give them a role, instructions, skills and recurring work — a reviewer, researcher, project partner, or something of your own.
• Make experience reusable. Keep useful preferences and knowledge in memory; turn a good way of working into a Skill you can reuse and share.
• Extend the product. Discover Skills and plugins in SkillHub, connect your own tools, or build on the official plugins.
• Help shape Cindy. Audit the code, fork it, improve an interaction, fix a bug, or contribute a useful integration. The client is Apache-2.0 licensed.

Open source means more than visible — it means changeable. Build Cindy with us →

Start with what you already have

The client is free. Authorize a supported subscription you already pay for, including Claude Code or Codex plans, connect your own API keys, or use a local model. You can also use Cindy's managed model service. Provider limits and billing still apply; the free client does not mean unlimited model usage.

For developers

This repository contains Cindy's open-source desktop and mobile clients and their shared packages, organized as a pnpm monorepo.

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.

Skill Hub migration uses two separate manifest fields: released clients keep using skillhubApiBaseUrl (the deprecated XD proxy), while current clients use cindySkillHubApiBaseUrl. The current client deliberately does not fall back to the legacy field when the new endpoint is absent.

Architecture

• DESIGN.md — visual design system, color tokens, and UI conventions
• docs/README.md — complete documentation and rules index
• docs/auth-realm-routing.md — organization SSO region discovery and session endpoint routing
• CONTRIBUTING.en.md — contributor setup, validation, and submission workflow
• AGENTS.md — engineering rules, launch/runtime contracts, and module boundaries
• docs/dev-rules/ — deep-dive architecture docs (e.g. Orca multi-agent orchestration)

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, including device identifiers, OS / app version, startup and activity events. Events are associated with your account ID after sign-in, so this is not fully anonymous. TapDB does not collect chat content, file content, or working-directory data.

You can disable usage analytics without editing code: on Desktop, use Settings → About → Usage statistics; on Mobile, use Usage statistics in Settings. The SDK checks the stored privacy-consent state and the statistics preference, which defaults to on. Accepting the Privacy Policy records consent; a one-time migration also records consent for eligible existing signed-in users.

Known Mobile exception: enterprise SSO skips the policy-acceptance step. If no analytics consent record exists and that sign-in is restored after restarting the app, the current migration can mark even a new installation as consented. With TapDB configured and statistics enabled, reporting can then start without explicit policy acceptance. See Mobile sign-in restoration and the consent migration. Turning off Usage statistics prevents reporting from being enabled by this migration.

• Desktop stops subsequent analytics reporting immediately when disabled. Local mode (Skip sign-in) does not report to TapDB.
• Mobile immediately unlinks the account and stops reports explicitly triggered by Cindy. An already initialized native SDK cannot be uninitialized; fully quit and relaunch the app to keep the SDK uninitialized.

Implementation: Desktop consent and settings, Desktop SDK, Mobile consent, and Mobile SDK.

Online heartbeats and diagnostic logs are separate mechanisms, unaffected by the usage statistics switch. Desktop sends heartbeats to Cindy services only during a verified cloud sign-in (account ID, platform, and version); local mode sends none. Desktop native crash dumps stay local and are never uploaded automatically. Diagnostic logs can be uploaded manually; a separate, default-off automatic crash log upload option is also available. Log uploads require privacy consent. See the heartbeat implementation and log upload rules.

Building from source? You are not required to keep analytics:

• Desktop development builds do not initialize TapDB by default. Explicitly setting XDT_TAPDB_DEV=1 lifts the build gate but still requires consent and the statistics preference. Self-packaged Desktop builds use the same analytics gates as official builds; you can disable analytics in Settings.
• Mobile does not initialize the SDK without injected TapDB configuration (clientId / clientToken). This does not mean all source builds default to off: the self-hosted release pipeline requires nonempty configuration, while local development permits empty values. See the Mobile build guide.
