SeeCode

SeeCode is an animated diagram generator that turns short JSON specifications from coding agents into explorable HTML files.

SeeCode generates animated, explorable diagrams from short JSON specifications provided by coding agents. It supports 42 diagram types including architecture components, flowcharts, sequence diagrams, and charts that take numbers from CSV or JSON files. Users can interact with the diagrams by hovering to trace connections, clicking to focus on specific nodes, walking routes step by step, and switching between light and dark themes or custom brand palettes. It imports existing formats like Mermaid, Graphviz, PlantUML, draw.io, Excalidraw, SQL, and OpenAPI. The final output is a self-contained HTML file that can also be exported as SVG, PNG, JPEG, GIF, or MP4.
