FluxMarkdown
FluxMarkdown is a macOS Markdown preview app and Quick Look extension for viewing Markdown files in Finder with rendered formatting, diagrams, and math.
What is FluxMarkdown?
FluxMarkdown is a native macOS Markdown preview app that helps users read and inspect Markdown files with formatted output instead of raw source text. It integrates with Finder Quick Look so you can preview .md files by pressing Space, and it also provides a full app for opening Markdown documents directly when you want more than a quick preview. Common use cases include reviewing README files, technical notes, documentation, and writing drafts without switching to a code editor. FluxMarkdown supports GitHub-flavored Markdown features and can render elements such as Mermaid diagrams, KaTeX math, tables of contents, and charts. It also includes export options for HTML and PDF, making it useful for developers, technical writers, students, and anyone who works with Markdown on Mac. Published by Xykong, it is best suited to productivity and documentation workflows on macOS.

Safety overview
Status: Mostly safe
FluxMarkdown is a legitimate Markdown viewer for macOS and its file access is consistent with opening and previewing Markdown documents. Users should expect it to read the files they choose to preview, and exported HTML or PDF files may contain the contents of those documents. If you work with sensitive notes or documentation, preview only files you intend to open and review exported files before sharing them.
Recommendation: Keep FluxMarkdown if you use Markdown regularly in Finder or want richer previews than macOS provides by default. If you no longer work with Markdown files, you can remove it without affecting macOS itself, but its Quick Look previews and export features will stop working.
