We built this to view Markdown files securely in our corporate environment as a lightweight alternative to firing up VS Code.

It’s just a single HTML file that executes entirely client-side. Alongside standard rendering, it supports floating navigation, clean print stylesheets, and exporting the result to a standalone HTML file (and it works great on mobile).
