A browser extension that renders Markdown files (local and remote) directly in Chrome, Firefox, Edge, and other Chromium-based browsers. It supports multiple Markdown parsers, 30+ themes, GFM, syntax highlighting, MathJax, Mermaid diagrams, and auto-reload on file change.

Use cases

• view markdown files in the browser
• render local readme.md files with chrome extension
• preview markdown with github styling
• render mermaid diagrams and mathjax formulas in markdown
• auto reload markdown preview on file change
• view remote markdown files with proper content-type detection

When to choose

• you read or write Markdown files and want them rendered nicely in the browser
• you need GFM, ToC, syntax highlighting, MathJax, or Mermaid support while previewing Markdown
• you want a secure, open-source viewer with granular control over which origins can render

When to avoid

• you need a full Markdown editor with live editing rather than a viewer
• you need to render Markdown outside the browser or in a CLI pipeline
• you require themes larger than the 8KB custom theme limit
