Drawing Diagrams in the Browser

Sometimes you need a quick diagram — a flowchart for a pull request, a wireframe for a feature idea, or a system architecture sketch for documentation. This canvas tool lets you drag and drop shapes, connect them with arrows, and export the result as an image.

What You Can Build

• Flowcharts — Map out decision logic, user flows, or process steps
• Wireframes — Quick UI sketches with rectangles, text, and connectors
• Architecture diagrams — Show how services, databases, and APIs connect
• Mind maps — Brainstorm and organize ideas visually

Your drawings are saved to the browser so they persist between visits. You can also export and import diagrams as JSON files to share with teammates or back up your work.
