LLMRender
I just wrapped up https://llmrender.com/, a tiny (10kb) Markdown to React renderer works with all of the Markdown + LaTeX math you'd normally expect in a normal project. I made it because doing one of the mainstream Markdown renderers + Katex (LaTeX) + Prism.js (syntax highlight) adds 300kb of gzipped JS to the frontend projects, so with this you can have it all for just 10kb. It also works well with streaming/does stable partial rendering. It supports features usually reserved for LLM chatbots, but also for normal everyday Markdown, so feel free to use it or give feedback!
