## How it works

- **Delegate:** Assign a task from Linear, Slack, or the dashboard.
- **Sandbox:** An agent works in an isolated dev environment.
- **Pull Request:** Review the PR and merge when ready.

## Integrations

- **GitHub:** Mention @tryreplicas in any PR comment to trigger a fix.
- **Slack:** Ping @Replicas in any channel to kick off tasks.
- **Dashboard:** Chat directly from the web for full control.
- **Linear:** Assign issues directly to Replicas to start implementation.

## Sandboxed environments

Each agent runs in an isolated VM with its own dev environment: install dependencies, run databases, and verify changes locally.

## Custom workflows

Integrate Replicas in any workflow and automate code changes.

```
POST /v1/replica
{
  "repository": "acme/app",
  "message": "Add dark mode",
  "coding_agent": "claude"
}
```

## FAQ

### What coding agents are supported?
Claude Code, Codex, Cursor, and Opencode.

### How is my code kept secure?
Each workspace runs in an isolated VM. Your code never leaves your connected repository, and we don’t train on your data.

### Do you store my code?
No. Only you have SSH access to your workspaces, and no code is stored in our databases. Sleeping workspaces are automatically deleted after 7 days of inactivity.

### What repositories can I use?
Any GitHub repository you have access to. Connect your GitHub account and select which repos to enable.

### How does billing work?
You get credits through subscriptions or by purchasing them directly, then spend those credits on usage. Pay only for active compute time. Workspaces automatically sleep when idle and wake on demand.
