mononykus Friday, February 13, 2026

After several months of development, we’ve just released the stable 1.0 version of ngDiagram – a free, open-source diagramming library built natively for Angular.

ngDiagram lets you easily add interactive diagrams to your Angular apps. Key features include: - Signal-based architecture for reactive updates - Native Angular components (HTML & CSS-first, fully accessible and customizable) - Drag & drop, multi-select, grid snapping, pan & zoom, custom nodes and edges - Middleware system for easy extension and integration with your data - Full TypeScript support and developer-friendly API

You can use ngDiagram to build dashboards, editors, flowcharts, network diagrams, or any tool that needs visual node/edge diagrams.

We’re actively developing ngDiagram based on community feedback, so your suggestions really shape the direction of the library. We’d love for you to test it, report issues, and help us make it better. If you like it, a GitHub star would be much appreciated!
