Branch the architecture
Propose a service, an edge, a whole subsystem. Review the diff, merge when the code lands — or throw the branch away.
Branch and merge your architecture
The map that keeps up with the code
Graphsky is a live C4 canvas for engineering teams. Import services straight from your repos, propose changes on a branch, and merge them when the code ships.
The C4 model, drawn properly
Every node says what it is
People, systems, containers and components each get their own colour, so a stranger can read your architecture without a legend. Draw the boundary once, and every edge shows who talks to whom — even the systems you don't own.

Import from code
Point Graphsky at a repository. It reads boundaries and dependencies and proposes the nodes; you keep the final say.
One canvas, whole team
Real-time cursors, comments on nodes, and a history you can scrub. The map stops rotting the day it ships.
