How It Fits Together
- Control plane
- A small always-on cloud node handles login and routing, so the hub stays up when a machine is switched off.
- Compute
- Each machine joins over an encrypted tunnel. Notebooks run on the machine you pick, not on the control plane.
- This page
- Plain static files on a global CDN, served from the edge nearest to you. No cookies, no analytics.
