Get started in minutes

Create your first cloud terminal or connect your own machine in just a few steps

1

Deploy Rexec

Run Rexec with Docker Compose for instant setup:
git clone https://github.com/brimblehq/rexec.git
cd rexec/docker
docker compose up --build
Access the UI at http://localhost:8080 with default credentials (admin/admin).
2

Create your first container

From the Rexec dashboard, click Create Container and select an image like ubuntu:24.04. Your terminal connects instantly via WebSocket.
Containers are network-isolated by default and destroyed when you close the session.
3

Connect via API or SDK

Use the REST API or one of our SDKs to programmatically create and manage terminals:
curl
curl -X POST https://your-instance.com/api/containers \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"image": "ubuntu:24.04"}'

  "image": "ubuntu:24.04",
  "status": "running",
  "created_at": "2026-03-04T12:00:00Z"
}
