Memos
FreeLightweight self-hosted note-taking for quick capture
About Memos
Memos is an open-source, self-hosted note-taking tool built for quick capture with 59,000+ GitHub stars. Think of it as a private Twitter or micro-journal where you jot down thoughts, ideas, and snippets throughout the day. The Markdown-native editor keeps things fast — no heavy page loads or complex formatting. Tags and filters organize notes without requiring folder hierarchies. The timeline view shows your thinking chronologically. An API enables integrations with other tools and automation workflows. Built with Go and React, it deploys as a single Docker container with SQLite storage by default, making it one of the simplest self-hosted apps to run. Resource usage is minimal — it runs comfortably on a Raspberry Pi. The mobile-friendly web interface works well on phones for on-the-go capture. Memos fills a different niche than full knowledge bases like Trilium or Obsidian — it is for the quick thoughts and fleeting ideas that you want to capture immediately without opening a heavy application. For users who find Notion overkill for daily note capture, Memos provides exactly the right amount of structure.
