Markdown Viewer & Editor
"MDHero is a beautiful, native Markdown viewer and lightweight editor for macOS and Windows.
Markdown is where developers, writers, and AI live today – READMEs, Claude Code plans, LLM chat exports, notes, documentation. But opening a .md file in a code editor gives you ugly monospace text. Opening a web-based viewer means uploading your files. GitHub renders it beautifully but only if the file is in a repo.
MDHero is a native app for everything in between. Your files stay local. Rendering is instant. Edit in place when you need to. Works offline. Looks like it belongs on your machine.
MDHero is open-source and built with Svelte / SvelteKit and Tauri."
