Mbox Viewer

A local-first tool to turn .mbox archives into readable, searchable HTML files.

I built this as a desktop app and CLI tool for converting mailbox exports into portable web files that are easy to open, search and share without a server.

Why this exists

A simple tool for mailbox archives that are hard to inspect.

The web version is useful for a quick peek, but it is not meant for large archives or sensitive data. The real value is in the desktop app and CLI workflow: process files locally, keep everything on your machine, and export an offline HTML archive you can search and open anywhere.

Project checklist
  • Converts .mbox to HTML
