DiceBear is an SVG avatar generation library and image API that creates deterministic profile pictures from seed strings. It provides a system for generating consistent visual outputs across different environments and programming languages using JSON style definitions.
The project distinguishes itself with a comprehensive design toolkit, including a visual style designer and a Figma integration plugin that converts design frames into JSON schemas. It supports sophisticated visual control through weighted probability distributions for components, contrast-aware color management for accessibility, and a transformation engine for randomized rotation and scaling.
Beyond basic generation, the system covers a broad range of capabilities including multi-format exports to raster images like PNG and WebP, a command line interface for batch asset production, and the ability to host a self-managed API for remote rendering. It also includes security features such as SVG output sanitization to prevent script injection.
