Local-first spatial thinking

Draw the shape of the work.

Nebula wraps Excalidraw in a Starscape-native shell for mission maps, diagrams, project canvases, and visual planning. The happy path is simple: open the canvas, think spatially, and keep your scene local in the browser.

Launch Nebula View source

Mission canvasSketch the architecture, journey, or next move.

Local sceneStored in your browser per board/canvas identity.

ExportableKeep Excalidraw compatibility as the drawing truth.

Canvas first

Drawing, editing, scene compatibility, and exports stay owned by upstream Excalidraw instead of a custom whiteboard engine.

Local by default

The deployed app opens as a browser-local workspace. No account, Firebase path, or remote persistence is required for v1.

Ready for Orbit

Nebula keeps board and canvas identity at the shell layer so it can become an Orbit/Suite module without coupling v1 to Suite.
