## 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?
Usage is measured in minutes of workspace runtime. Every plan includes a monthly allowance of minutes, and you pay only for active compute time. Workspaces automatically sleep when idle and wake on demand.
