Memos

Memos is an open-source, self-hosted web app and server for note-taking. It functions as a note-taking tool designed for quick capture, utilizing a private timeline interface rather than a traditional folder hierarchy. Users deploy the software on their own infrastructure to maintain full control over their data and avoid reliance on third party cloud providers.

The application is available as a web app and can be deployed via a Docker image, a native binary, or Kubernetes. It supports multiple database backends including SQLite, MySQL, and PostgreSQL. The system is designed for lightweight operation, with the Docker image occupying approximately 20MB, making it suitable for deployment on small servers or home lab environments.

Key features

• Timeline-first user interface for instant note capture
• Markdown-native formatting for all entries
• Self-hosted deployment to ensure data ownership
• Zero telemetry collection
• Support for SQLite, MySQL, and PostgreSQL databases
• REST and gRPC APIs for external integrations
• MIT license for open extensibility

The software is built using Go and React. It targets users who prefer a microblogging style of note-taking where entries are added chronologically rather than organized into complex nested structures. Because it provides full REST and gRPC API access, it can be integrated into other automated workflows or external software systems. The architecture emphasizes portability and minimal resource consumption, which allows the application to run efficiently on modest hardware without requiring significant system overhead.

By removing the need for folder setup and navigation, the tool focuses on the speed of recording thoughts. It is intended for individuals who want a private space for memos that remains fully portable and accessible via a browser. The use of Markdown ensures that notes are not locked into a proprietary format and can be moved easily if needed.

Memos is a lightweight personal knowledge management tool for those who prioritize data sovereignty and speed of entry.
