A shared workspace contract
Repository sets, branches, and environment expectations travel with the work, so humans and agents start with the same context.
Agent-assisted engineering
Many repositories.
One way forward.
Give your agents and your team a shared way to work. X4 connects reproducible workspaces, orchestration, and remote execution—with evidence you can review.
One operational layer. From the first checkout to the final review.
The X4 workflow
-
Prepare together
Connected repos. Reproducible workspaces.
-
Coordinate the work
Agents and humans, with a shared plan.
-
Validate remotely
Run checks in controlled execution environments.
-
Bring the evidence
Logs, artifacts, and checks for human review.

Tailscale required
Control
Your operations workspace. Monitor infrastructure with Fleet and manage model connections with Gateway.
Open Control
Tailscale required
Factory
Turn issues into plans and implementation. Follow coding-agent sessions and bring changes through review.
Open FactoryControl and Factory are private workspaces. Connect to your organization’s Tailscale network before opening them; your existing sign-in and permissions still apply.
Execution with clear boundaries
Coordinate work through the CLI and control plane. Run validation remotely and keep private previews inside your network.
Evidence attached to the change
Use generated logs, artifacts, and check results to understand what ran and make an informed review.
