Developer Builds Full-Featured Browser Whiteboard App Entirely with Claude
vinishkapoor · reddit · 2026-08-09
A developer shares their experience building a complete web-based whiteboard app using Claude. The tool requires no installation or signup and supports freehand drawing, geometric shapes, text input, and image embedding.
Key features include:
- Rich drawing tools: Supports pen, rectangles, circles, arrows, and lines, with controls for stroke width, style, and opacity.
- Hand-drawn aesthetics: The author notes that achieving a natural 'sketchy' look was the most iterative process, ultimately solved by Claude using a procedural wobble algorithm.
- Import/Export: Supports export to PNG (with/without background), PDF, and project save/reload.
The tool is currently free and open to use, ideal for quick architecture diagrams and wireframes.
