I built a beautiful Markdown Viewer for Chrome, VS Code, and Desktop — here's what I learned

The Problem Every developer reads Markdown daily — READMEs, docs, notes. But the default rendering is... boring. Raw GitHub files look plain. VS Code's built-in preview is basic. And if you want Mermaid diagrams or LaTeX math? Good luck. I wanted one tool that renders Markdown beautifully — everywhere I work. The Solution: Markdown Viewer Premium 💎 A single React UI core, deployed as: 🌍 Chrome Extension — renders .md files directly in the browser 💻 VS Code Extension — replaces the default Markdown preview 🖥️ Desktop App — native app built with Tauri v2 Features Syntax Highlighting (100+ Languages) One-click copy button on every code block. Supports JavaScript, Python, Go, Rust, SQL, and 100+ more. Mermaid Diagrams Flowcharts, sequence diagrams, gantt charts, pie charts — all rendered natively. Click to expand fullscreen with zoom & pan controls. Math & LaTeX Render equations beautifully with KaTeX — inline and block math supported. And More... GitHub Alerts — NOTE, TIP, IMP
