Streamdown is an open-source React component that renders Markdown as it streams in from AI models. Forked from react-markdown and hardened for streaming, it keeps formatting stable while tokens arrive — with built-in typography, streaming carets, animations, Shiki code blocks, KaTeX math, Mermaid diagrams and CJK support.
