I built Markdown Viewer Premium because I was tired of the outdated, unstyled look of existing local markdown viewers. As developers, we spend so much time in .md files (READMEs, documentation), I wanted an experience that felt like a polished documentation site.
It’s a Chrome extension that intercepts local .md file requests (and raw GitHub URLs) to render them with a modern "Glassmorphism" UI.
Key Features:
Mermaid & KaTeX: Auto-renders diagrams and math equations. I added a zoomable lightbox for complex flowcharts. GitHub Integration: Paste a raw GitHub blob URL, and it renders instantly. Tech Stack: Built completely fresh with React 19, Vite, and TailwindCSS (no legacy jQuery/bootstrap code). Privacy: It runs entirely client-side; no data is sent anywhere. It's open source and I'd love to hear your feedback on the typography and rendering choices!
