System Design EditorCollaborative Architecture & Planning

Real-time peer-to-peer diagrams, requirement traceability, and capacity planning.

Real-Time Peer-to-Peer Collaboration

Direct browser-to-browser WebRTC synchronization powered by Yjs. Nothing passes through a server unless you add a workspace.

Link diagram components directly to requirements with bi-directional navigation and drill-in support.

Program Increment (PI) planning with capacity reservations, team allocation, and interactive timelines.

Optional team storage the server cannot read. Documents are sealed in the browser; the store holds ciphertext and wrapped keys.

The editor deploys as a pure static bundle with no runtime database. Fully operable in restricted or isolated networks.
