Integrations / Slack
A coding agent you can tag in Slack.
Mention @Replicas in any channel or thread, or DM it. Replicas reads the thread, starts Claude Code, Codex, Cursor or OpenCode in an isolated cloud VM with your repos, and replies in the same thread with what it did and a link to the pull request.
Updated
How it works
From Slack to a reviewed pull request.
- Trigger in Slack
@Replicas in a thread or DM
Replicas picks up the request with its context.
- Isolated cloud VM
Your agent works on your repos
Claude Code, Codex, Cursor or OpenCode runs in its own VM with your environment, and can run tests.
- Result
Reply in the thread with a PR link
Review the changes with your team before merging.
From Slack
What the agent can do from Slack.
| You | Replicas |
|---|---|
| Mention @Replicas in a channel or thread | Reacts 👀, starts a workspace and replies in the thread |
| DM the bot | Treats every message as a task, no mention needed |
| Reply in the same thread | Routes to the same workspace, waking it if it slept |
| Attach screenshots or recordings | Images in the thread go to the agent as context |
| Add [env:backend] to the message | Picks that environment instead of the default |
| Start the message with /plan | Returns a plan before any code changes |
| Fork task from the message menu | Starts a separate task without stopping the first |
| Merge or close the PR | Posts the outcome back to the original thread |
