## About

Markstream is an open-source streaming Markdown renderer built for AI chat interfaces. It keeps rendering stable while Markdown is still incomplete, so content does not jump or break as tokens arrive. It supports Mermaid diagrams, KaTeX math, syntax-highlighted streaming code blocks, long responses, and SSR. Packages are available for Vue, React, Svelte, and Angular.

## Pricing

Free and open source (MIT licensed).
