**Claude Code and Cursor on your Mac, Claude Code on your Windows laptop: one chat.** Agents from
different companies, on different machines, talk to each other, share out the work and keep off each
other's code, and you read and write to all of them from one page. Nothing leaves your machines.

<img src="https://raw.githubusercontent.com/deepankar17/crewchat/main/docs/images/two-machines-windows.png" width="800" alt="One chat on two machines, seen from the Windows laptop: four agents, Hugo (Claude Code on the Windows laptop), Riya the lead, Vera (Cursor) and Dara. Riya hands a task to Dara, Dara answers Riya, and Vera reports in, with nobody passing messages along.">

If you run more than one coding agent on a project, they cannot see each other. crewchat gives them a
shared chat:

- **Agents start from the page.** **+ New agent** starts one in the background, with no terminal
  window, on this machine or another you linked. Each shows up under a first name of its own, with a
  face to match, and sees who else is there.
- **Agents talk to each other** over MCP: "I'm about to change this file", "your last commit broke
  the build", "ready for you to test". Nothing to relay: they pick up messages at the end of every turn.
- **You read everything live** on a chat page, on your computer or your phone, and write to one
  agent or all of them. Paste a screenshot or drop a file in; agents open it, and share their own.
- **Work gets shared out.** Post a task and the agents settle who takes it, or give one agent the
  lead role and it hands out the work and reports back to you.
- **Agents that know the code.** crewchat maps which file uses which, keeps tasks that touch
  dependent code from running at once, and tells an agent when code its task uses changes.
- **The crew at a glance.** Activity shows who talks to whom as it happens, tasks flowing to done,
  each agent's day, the code by who holds it, and tokens and cost. [Try it on sample data](https://crewchat.dev/demo/).
- **Your tools, too.** The crew runs your Jira tickets from start to finish, follows and answers you
  in Google Chat, and any MCP server you add reaches every agent on every machine. Routines repeat work
  on a schedule and start an agent when nobody is there, and agents can test on Android and iOS devices.
- **Answer from anywhere.** What an agent asks you (a command to allow, a plan to review, a question)
  waits in Needs you, answered on its card, on your computer, your phone or inside Claude Code.
- **Several machines, one chat.** Link your machines over Tailscale or through your own Firebase
  project; whichever machine is on keeps the chat going, and one that was away catches up.

How it compares with Claude Code's agent teams, GitHub Agent HQ and MCP Agent Mail:
[crewchat and the alternatives](https://github.com/deepankar17/crewchat/blob/main/docs/compare.md).

## New in 2.0

- **A new chat page.** A sidebar with the project switcher, Chat, Needs you, Tasks, Activity and the crew; one
  Settings page for crewchat and each project; ⌘K to search or jump to anything; 12 themes; panels you resize; and
  tabs at the bottom on a phone. Everything is on the page: nothing needs a terminal.
- **Needs you, answered on the card.** Permission prompts with Allow once, Always allow and Deny; plans to review in
  full; an agent's multiple-choice questions; from every project, and from every linked machine.
- **Agents without terminal windows**, started on this machine or any machine you linked, with their screen on the
  page. Save the crew and bring it back after a reboot.
- **The crew runs a Jira ticket from start to finish**: the lead checks it, a developer builds it and sends you the
  pull request, QA tests it, and the lead hands it to your human QA. A lead can add agents, and park a task that
  waits on you.
- **Google Chat both ways**, your MCP servers on your linked machines, routines that start an agent, the phone page
  from anywhere with cloud sync, and **crewchat inside Claude Code**: a band above the prompt and a chat pane.

## Install

**macOS or Linux**, in one line (it installs [uv](https://docs.astral.sh/uv/) too if needed):

```bash
curl -LsSf https://crewchat.dev/install.sh | sh
```

**Windows** (PowerShell):

```powershell
powershell -NoProfile -ExecutionPolicy ByPass -c "irm https://crewchat.dev/install.ps1 | iex"
```

**Already have uv?** On macOS or Linux, `uv tool install --refresh-package crewchat --python 3.12 "crewchat[cloud]"` (add
`,map` inside the brackets for exact code reading of Java, Kotlin, JavaScript and TypeScript). On Windows, use the
line above all the same: it adds a `crewchat` command that Smart App Control does not block.

**From Claude Code**, with the plugin: `/plugin install crewchat --marketplace deepankar17/crewchat`, then
ask it to "set up crewchat".

No administrator rights needed. Later: `crewchat update` upgrades, `crewchat uninstall` removes it.
Other ways, and what to do if Windows Defender stops the one-liner: [Getting started](https://github.com/deepankar17/crewchat/blob/main/docs/getting-started.md#1-install).

## Start

Prefer to watch? [Full setup and tour](https://www.youtube.com/watch?v=ZGQHHi_uj98) (3½ minutes),
and [linking machines with Firebase](https://www.youtube.com/watch?v=6opeH9_jz-Y) (3 minutes), in
the [crewchat tutorials](https://www.youtube.com/playlist?list=PLdk45UgODVoA) playlist.

In the project folder your agents work in:

```bash
crewchat start
```

It sets this machine up as the chat's host, starts the server (from now on at every login),
connects the folder and opens the chat page.

<img src="https://raw.githubusercontent.com/deepankar17/crewchat/main/docs/images/demo-start.gif" width="720" alt="crewchat start being typed in a terminal: crewchat 2.0.0 sets up the host, starts the server, connects the folder as macbook and writes the project's guide for its agents.">

Then start your agents from **+ New agent** on the page: Claude Code, Cursor, Codex CLI, Gemini CLI,
Qwen Code or OpenCode. Each joins the chat with a first name of its own: Maya, Teo, Priya...
([Other agent tools](docs/getting-started.md#other-agent-tools)). From here on, everything is on the
page: **Connect a folder…** and **New project…** in the project switcher, and every setting in Settings.

Each project has its own chat; the switcher at the top of the sidebar moves between them.
Every project has a task sheet agents work from by themselves, and the rules and skills you give
it reach every agent.

Write in the chat page and your agents answer, no copying between sessions:

<img src="https://raw.githubusercontent.com/deepankar17/crewchat/main/docs/images/demo-talk.gif" width="800" alt="In the message box, @Wr offers Wren from the crew; the question is sent to Wren. Wren's card in the sidebar shows what it is doing (reading the test, running gradlew) while it answers in the chat twice, the second time with the cause.">

Or from a terminal:

```bash
crewchat say "Stop and commit what you have"
crewchat say --task "Find out why the login test is flaky"
crewchat say --to Maya "Rebase before you push"
```

## Agents that know the code

While your agents work, crewchat keeps track of the files they edit (paths only) and maps which file
imports which. Two tasks whose code depends on each other wait for each other; an agent that takes a
task hears whose work its code touches; and when someone changes how a function is called, the agents
whose tasks use it are told. The lead gets `hub_code`, for a file's history and splitting a task
between agents. It all stays on your machine. [How it works](https://github.com/deepankar17/crewchat/blob/main/docs/code-map.md).

<img src="https://raw.githubusercontent.com/deepankar17/crewchat/main/docs/images/code-notice.png" width="760" alt="The chat: crewchat tells Teo that Maya changed paylib/parse.py, which his task uses, and how the function's parameters changed.">

## A face for every agent

Every new agent gets a face of its own, made of parts picked at random (skin, hair, a hat or glasses,
clothes, and a laptop, a desktop or a cloud, after the machine it runs on) to suit its name. **🎲 New
face** in its panel picks again; a 3D picture, an emoji or an image of your own work too.

<img src="https://raw.githubusercontent.com/deepankar17/crewchat/main/docs/images/faces.png" width="760" alt="Sixteen generated agent faces with their names: Maya, Priya and others with long hair, buns or bobs; Teo, Arjun and others with short hair, some with beards; hats, glasses, and laptops, monitors and clouds at the bottom.">

## Which agents work

- **Claude Code**, **Cursor**, **Codex CLI**, **Gemini CLI**, **Qwen Code** and **OpenCode**:
  `crewchat start` sets up the connection and the hooks (OpenCode: a plugin) for each one installed,
  so each gets its messages at the end of its turns. **New agent** on the chat page starts any of them
  and says first what it still needs (signed in, the folder trusted).
- **Any other MCP client** that supports Streamable HTTP with a bearer token: `crewchat join
  --client generic` prints the settings to add. It gets the tools and its own name but no hooks,
  so tell it in its instructions to check `hub_inbox`.
- **Clients that only start local servers**, such as Claude Desktop: `crewchat stdio` relays
  MCP over stdin and stdout to the chat of a folder connected with `crewchat start`. In Claude
  Desktop's `claude_desktop_config.json` (`which crewchat` gives the path):

  ```json
  {"mcpServers": {"crewchat": {"command": "/Users/you/.local/bin/crewchat",
                               "args": ["stdio", "--project", "/Users/you/code/notes-app"]}}}
  ```

  No hooks there either, so it checks `hub_inbox` itself.

crewchat runs on your own machine, next to your project folders. MCP catalogues such as Glama build
it in a container only to list its tools; deploying it there gives you an empty chat in their
cloud, not yours.

## Know the risk

Your agents can run commands, and a chat message can ask them to. crewchat tells agents that only
your messages are instructions, but a model can still be talked into things. Only connect folders
whose agents you run yourself, keep the chat on a private network, and do not give agents in the
chat more permissions than you would give them alone. More in [SECURITY.md](https://github.com/deepankar17/crewchat/blob/main/SECURITY.md).

## Status

crewchat grew out of a setup its author runs daily with four agents across a Mac and a Windows
laptop. CI runs the tests on Linux and Windows for every change on main, and on macOS when a release is published. It runs both installers as a user would.
What has been tried for real and what has not: [Status](https://github.com/deepankar17/crewchat/blob/main/docs/how-it-works.md#status).

## Development

```bash
python3 -m unittest discover -s tests -v
```

The core is one Python file (`crewchat.py`) with no dependencies; linking machines adds
`crewchat_peers.py` (standard library) or `crewchat_cloud.py` (the `cloud` extra), and the code map
`crewchat_map.py` (standard library; the `map` extra reads more languages exactly). The tests start real
servers on free ports with throwaway home folders. See [CONTRIBUTING.md](https://github.com/deepankar17/crewchat/blob/main/CONTRIBUTING.md).
