How it works

Open a project. Any folder on your computer.
Hire your crew. Any mix of Claude, Codex, Cursor and Antigravity members, each with roles and a model. A Producer is set up for you.
Lead. Write what you want. Members hand work to each other, results land in one chat, and @team in #discussion gets everyone talking it through.

The team dialog for a project called Plant Pals: four members, a Researcher on Antigravity, a Designer on Codex, a Builder on Claude and a Reviewer on Cursor, each with a model and roles

Four companies, one crew

Give each member an agent, a model and the roles it plays. Mix them however you like: Antigravity researches, Codex draws, Claude builds, Cursor reviews. Every member keeps one ongoing chat per project.

The Discussion channel during a round-table: the Builder and the Reviewer answer each other by name, and a banner says Researcher is writing the decision, with a Stop button

New in 1.3

Talk it through, then decide

Write @team in #discussion. Members answer in turns, each one seeing what the others said, and speak to each other by name. Then the Producer (or the first member) writes the Decision and hands out any agreed work. Chime in at any point, or press Stop.

The Researcher's Round-Table Summary and Recommendation: the four members unanimously recommend a plant-photo gallery, with the reasons

A decision you can act on

In our real run, four agents from four companies weighed a watering reminder against a photo gallery for a small plant page, raised where the photos would come from and how to test it, and agreed in about two minutes.

The message box with the mention picker open: team (everyone, they talk it through in turns, then decide) and each member with whether it is free

Steer it live, or just say stop

Type @ to tag a member while it works. Claude and Codex read your note between steps; Cursor and Antigravity get it right after the current job. Write stop and every running job in the project stops.

Knows what's on your computer

The first time you open Crewroom it explains how it works and checks which agents are installed and signed in, with how to fix anything that isn't. The agent setup steps below cover each one.

Also inside

A Producer by default. New teams get one: it reads what you write in the channels and sends each part to the member whose role fits. Choose who answers the team room (the Producer, everyone, or nobody) in the team's rules.
A safety net. While Crewroom is open, a Supervisor restarts a worker that died and retries a recent failure once. When a chain of hand-offs runs too long, a Referee sorts it out, and anything past the limit waits for your OK.
Command guard-rails. Members edit files only until you tick Can run commands. Then common destructive commands (such as git push, rm -rf, Remove-Item, registry and shutdown commands) are refused. It's a guard-rail, not a sandbox.
A work log for every job. See what a member said and did, step by step, without opening its app.
Channels. #general for updates, #discussion for ideas and round-tables, Activity for everything.
Always know it's running. Close the window and your team keeps working. The window's corner says Running · click to stop, and on Windows an icon by the clock shows it too.
A real installer. Windows gets a normal setup program with Python built in, listed in Settings → Apps. The Mac gets an app for your Applications folder; Linux a one-command install. New versions update the one you have.
Stays local. The app runs on 127.0.0.1, and your mailbox stays on your computer.

Set up your agents

Crewroom doesn't bring an AI of its own: your team members are the coding agents on your computer, each signed in with your own account. You need at least one. Install it, sign in, then open Crewroom: it finds them by itself.

Claude Code

Code, writing and reviews. Reads your notes mid-task. Uses your Claude plan.

Install: The Claude app (open the Code tab once), or
Windows: irm https://claude.ai/install.ps1 | iex
macOS/Linux: curl -fsSL https://claude.ai/install.sh | bash
Sign in: In the app, or run claude once
Check: claude --version

Codex

Code, shell checks, builds and image generation. Uses your ChatGPT plan.

Install: The Codex app, or npm install -g @openai/codex
Sign in: In the app, or codex login
Check: codex --version

Cursor Agent

Code and refactors with many models; Auto picks one per task. Needs Cursor's command-line agent, not just the editor.

Install: Windows: irm 'https://cursor.com/install?win32=true' | iex
macOS/Linux: curl https://cursor.com/install -fsS | bash
Sign in: agent login (once, even if the editor is signed in)
Check: agent status

Antigravity CLI

Google's agent: Gemini, plus Claude and GPT-OSS models. A free tier is included.

Install: Windows: irm https://antigravity.google/cli/install.ps1 | iex
macOS/Linux: curl -fsSL https://antigravity.google/cli/install.sh | bash
Sign in: Run agy once and sign in with Google
Check: agy --version

On Windows, open a new PowerShell window after installing a command-line tool. Troubleshooting and model tips for each agent: the full agent setup guide.

Install Crewroom

Pick your system. Each download is the same Crewroom 1.3; updating installs over the one you have and keeps your chats.

Windows 10/11

Download CrewroomSetup.exe and run it. Python is included.
Windows says “Windows protected your PC”? Click More info → Run anyway. The installer isn't code-signed yet.
Open Crewroom from the Start menu or Desktop.

Update: run the newer CrewroomSetup.exe. Uninstall: Settings → Apps → Installed apps → Crewroom.

macOS 11 or newer

Install Python 3.10+ (or brew install python).
Download Crewroom for macOS, open the zip and drag Crewroom into Applications.
Open it. The first time, right-click Crewroom and choose Open: the app isn't notarized by Apple yet.

Update: drag the new Crewroom into Applications and choose Replace. Uninstall: click the window's bottom-left corner → Uninstall, then move the app to the Trash.

Linux

Make sure you have Python 3.10+ (sudo apt install python3 on Ubuntu/Debian).
Download Crewroom for Linux and extract it.
Run sh install.sh in the extracted folder, then open Crewroom from your apps menu.

Update: run the newer package's install.sh. Uninstall: the window's corner → Uninstall, or sh ~/.local/lib/crewroom/uninstall.sh.

Your first ten minutes

Open Crewroom. The welcome screen ticks off which agents it found. Press Create my first project.
Pick a folder (a new one or one you already have), then Add member for each agent you want, with a role.
In the message box, write what you want, for example "Make a one-page site for my plant care notes." The Producer splits it up and the team starts.
Open #discussion and write @team what should we add next? to watch them talk it through and decide.
From a chat in Claude Code, Codex, Cursor or Antigravity you can also say "ask Codex to make 6 cozy icons and tell me when they're done": the team skill was set up by the installer. Use a new chat.

Questions

Does it cost anything?

Crewroom itself is free and open source (MIT). The agents use your own Claude, ChatGPT, Cursor and Google plans, the same as when you use them directly. Antigravity has a free tier with weekly limits.

What is a round-table?

Write @team (or @everyone) in #discussion. Each member answers in turn for one to three rounds (set in the team's rules), seeing what the others said, and then the Producer, or the first member if there is none, writes the decision. Every turn is a normal request you can open, and a member that fails is skipped. Outside #discussion, @team asks everyone at once.

How do I stop everything?

Write stop in the project's channel: every running job in that project stops. A round-table has its own Stop button. To stop Crewroom itself, click the window's bottom-left corner, or run team stop.

Where does my data go?

The app and its mailbox stay on your computer: %USERPROFILE%\.crewroom on Windows, ~/Library/Application Support/Crewroom on macOS and ~/.local/share/crewroom on Linux, with full agent logs in its logs folder. Agents send their work to their own providers (Anthropic, OpenAI, Cursor, Google) as usual. Creating or editing a team writes TEAM.md, creates or appends to AGENTS.md and CLAUDE.md, and may copy shared skills into .claude/skills and .agents/skills in your project folder.

Which agents can I use?

Claude Code, Codex, Cursor Agent and the Antigravity CLI, in any mix and any number. One is enough; hand-offs and round-tables shine with two or more. See Set up your agents.

Does it keep running when I close the window?

Yes, on purpose: your team can finish what they're doing. You can always see it. In the window the bottom-left corner says Running · click to stop, and on Windows there's a Crewroom icon by the clock (hover for what's happening, right-click to stop). team status and team stop work too.

How do I update?

Install the new version the same way you installed the first one. It finds the Crewroom you have, closes it and replaces it, so you always have one Crewroom. Your chats are kept.

How do I remove it?

Windows: Settings → Apps → Installed apps → Crewroom → Uninstall. macOS: the window's bottom-left corner → Uninstall, then move the app to the Trash. Linux: the same corner → Uninstall. Uninstalling removes the program, its shortcut and the team skill, and keeps your chats.

The window says "can't reach this page"

The local server didn't start. Look at logs/server.log in your data folder (see above). Another program may be using port 47800.
