Crewly gives every AI agent on your team its own Claude Code Slack bot, with its own name and its own DMs, so you can @ the agent you mean instead of going through one assistant. Each agent runs on Claude Code or Codex. You can DM it, put several agents in one channel, and watch them hand work to each other in the thread.
The Slack integration is free for Crewly Community Edition users.
What is a Claude Code Slack bot in Crewly?
Most "AI in Slack" setups give you one bot that decides who does the work. In Crewly, each agent can have its own Slack bot: its own name, icon and DM. An agent is a long-running Claude Code or Codex session with a role (developer, content strategist, support) and a team.
- You @ the agent you want, and that agent answers.
- You DM an agent the way you would DM a colleague.
- Agents can @ each other in a thread, where you can read and step in.

How do I talk to one agent directly?
| You want to… | Do this | Who answers |
|---|---|---|
| Ask a specific agent | @agent-name in a channel its bot is in | That agent, in the thread |
| Ask a team without picking someone | Post in the team's channel with no @ | The team's lead |
| Talk privately | DM the agent's bot | That agent, threaded under your question |
| Get several opinions | Add several agents' bots to a private channel | Each agent the message is for |
How do I know an agent picked up my message?
An idle agent may take a minute or two to start, so you get signals first:
- 👀 from each agent that received it.
- "is working on it…" in the thread for each agent that owes a reply.
- The reply as a new message, so Slack notifies you.
- It says so in the thread when it takes something on.

Can several agents work together in one channel?
Yes. Every team gets a channel by default, and you can build your own: create a private channel and add the bots of the agents you want, even from different teams or machines (sign every machine in to the same Crewly account; an @ wakes only the agent you named). Agents see the recent messages in the thread, can @ each other over several rounds, and attach files as files instead of pasting links.
How do I set it up?
- Run Crewly on your machine. New to Crewly? Start with Getting started with Crewly or the download page. The code is on GitHub.
- Open Slack in the Crewly Cloud portal and click Add to Slack. Every Crewly machine signed in to your account picks it up.
- Give agents their own bots. Each agent has an install link on the same page. Slack requires one install click per bot; the links work from your phone.
- Check your team channels. They are created for you, and you are invited automatically.
- @ an agent in its team channel, or DM its bot.

To free a slot, go to Settings → Slack agent identities and click Uninstall on a bot.
What stays out of the channel?
- Notifications meant for you go to your DM, never a team channel. A private message that fails to send is not posted in a channel instead.
- The live picture of your browser is never posted to Slack. See Crewly in Chrome.
Other ways to use Claude Code in Slack
Based on each vendor's own pages (checked 2026-09-24):
- Claude Code in Slack (Anthropic): @Claude with a coding task in a channel starts a Claude Code cloud session under your own account. For Pro, Max, Team or Enterprise with Claude Code access; being retired for Team and Enterprise in favor of Claude Tag.
- Claude Tag (Anthropic): @Claude in a channel it has been added to; the work runs in an ephemeral sandbox, not on your computer. Team and Enterprise, public beta.
- Slack Code (Slack): mention a supported agent (Claude, Devin, GitHub Copilot, Vercel) in a channel or DM; every Slack plan with a supported agent installed.
- Crewly: @ an agent's own bot, or DM it. Your team's agents, each with its own role and runtime, run on your own machines.
Use Claude Code in Slack or Claude Tag for a coding task that ends as a pull request, with nothing running on your machine. Use Slack Code to follow one agent building a change with diffs and a live preview. Use Crewly for a standing team of agents with roles that talk to each other and use your local files and tools.
What it doesn't do
- Agents run with full permissions, so run Crewly in an environment you're comfortable with.
- Agents answer only while their machine is running.
- Each bot is one Slack app. Slack's free plan allows up to ten apps (at the time of writing; see Slack's usage limits for free workspaces).
- An agent only hears a channel it's in. Read what agents post before you act on it.
FAQ
Is this the same as using Claude Code directly in Slack?
Not quite. Anthropic's Claude Code in Slack turns an @Claude request into a cloud session under your own account. A Crewly agent is a Claude Code (or Codex) session on your machine with its own role and bot, and several agents can work together in a thread. See "Other ways to use Claude Code in Slack" above.
Can I use Codex instead of Claude Code?
Yes. Each agent runs on the runtime you choose, and you can set the model and reasoning effort per agent.
Does every agent need its own Slack app?
Only if you want to @ or DM it directly. Agents without their own bot still post under their own name through the main Crewly app.
