Memos

Memos is a lightweight, self-hosted note-taking application designed for quick capture. Open it, write a note in Markdown, and move on. Notes appear in a chronological timeline, closer to a private microblog than a traditional folder-based notes app, which suits the kind of stray ideas, links, commands, and reminders that normally end up scattered across sticky notes and chat-to-self threads.

The deliberate simplicity is the point. There is no title required, no folder to choose, no template to fill in. Just text, tags, and links, stored privately on your own server. It runs as a single Docker container backed by SQLite, so there is essentially nothing to configure beyond starting the container, and it runs comfortably on hardware as modest as a Raspberry Pi.

Markdown support covers tags, task lists, links, and code blocks. Notes can be kept private or shared individually. The 60,000 GitHub stars and rapid development pace reflect how well this fills the “quick capture” niche that heavier tools overcomplicate.

The honest scope: Memos is not a replacement for a structured knowledge base. It has no nested notebooks, no wiki linking, no long-form document organisation. If you need those, Trilium or Joplin serve that purpose. Memos is the tool for the notes that should be saved now and organised never, the digital equivalent of a notebook you jot in and rarely reread but are glad to have when you need it.
