Block Diagram Editor
Browser-based tool
Draw technical block diagrams in your browser and export them to LaTeX and PNG.
Create technical block diagrams with a 1, 5 or 10 mm snapping grid. Draw rectangles, lines, arrows and bidirectional arrows; adjust colors, labels, sizes and stacking order. Rectangles and triangles also support zero-width outlines for borderless background shapes.
The editor runs locally in your browser with a built-in English / German language switch. Your language preference is saved locally. Save editable JSON projects, export PNG or LaTeX, and download the compatible TikZ macro library.
