Flowscape

Flowscape is a TypeScript-first 2D graphics engine designed as a foundation for editor-like applications such as design tools, whiteboards, diagram editors, and visual builders. It provides scene management, rendering, hit testing, and infinite canvas capabilities without locking projects to a specific frontend framework.

The engine includes built-in node types (rectangles, ellipses, paths, text, images), a paint system supporting multiple gradient types, and editor-oriented features like pan/zoom, selection overlays, and bounds calculation. The maker says it was built with Claude Code. Developers can extend functionality through a plugin system and custom rendering workflows.
