About

Mdview is a lightweight, fast Markdown viewer for Windows that opens and previews .md files directly in your browser. It renders README files, Mermaid diagrams, LaTeX math, tables, and code blocks, giving you a true‑to‑form preview without leaving your editor. The desktop version is minimalistic and responsive, while the online viewer works on any browser. It is ideal for developers who need quick, accurate Markdown previews.

The case

Who it is for

Developers and technical writers who edit Markdown documentation and need a fast, accurate preview of README files, diagrams, math, tables, and code.

What is broken today

Before Mdview, developers had to rely on full‑featured editors or web‑based preview services that were either heavy, slow or lacked support for advanced Markdown features like Mermaid diagrams or LaTeX math. This made it difficult to quickly view and verify the formatting of documentation before committing to the code repository.

What it does about it

Mdview is a lightweight desktop application that opens .md files and renders them in a browser‑like window. It parses Markdown syntax, renders tables, code blocks, Mermaid diagrams, and LaTeX math, providing a true preview of the final rendered document. The online viewer works in any browser, allowing instant preview without installation.

Why not the obvious alternative

Unlike general‑purpose editors or browser extensions, Mdview is dedicated to Markdown preview, offering a minimal UI, fast rendering, and built‑in support for Mermaid and LaTeX without the need for plugins. It runs locally on Windows and has an online version for quick access, giving developers a single tool that covers all common Markdown preview needs.
