Self-hosted, privacy-first note-taking platform with full Markdown support
Memos offers a lightweight, self-hosted knowledge base with instant saving, rich Markdown, media embedding, and cross-platform access, ensuring full data ownership and zero external dependencies.
Memos is a self-hosted knowledge-management platform built for users who value privacy and performance. It stores every memo locally in a database you choose—SQLite, PostgreSQL, or MySQL—so you retain full ownership and can back up the data directory at any time.
The interface offers instant-save plain-text entry with rich Markdown rendering, syntax highlighting, and native media embedding. A modern React front-end delivers a responsive experience across Linux, macOS, Windows, or any Docker-compatible host. An API-first design lets developers create, read, update, and delete memos programmatically, while configurable themes and branding let organizations tailor the look and feel.
Memos can be launched in under a minute using the official Docker image, or installed as a binary on supported operating systems. Minimal system requirements and a single-container footprint keep resource usage low, making it suitable for personal servers, small-team intranets, or edge devices.
When teams consider Memos, these hosted platforms usually appear on the same shortlist.
Looking for a hosted option? These are the services engineering teams benchmark against before choosing open source.
Personal knowledge repository
Capture, organize, and retrieve research notes securely on a local machine.
Internal documentation for a small company
Host a private wiki for policies, SOPs, and project notes accessible via web browser.
Developer API documentation
Store and serve API specs in Markdown, leveraging the REST API for integration with CI pipelines.
Meeting minutes archive
Record, tag, and share meeting summaries with media attachments, searchable across the organization.
All notes, uploads, and settings are saved in the chosen database (SQLite, PostgreSQL, or MySQL) within the mounted data directory; backing up that directory preserves everything.
No. Once deployed locally, Memos runs entirely offline; external connectivity is only required for initial image download or updates.
Yes. Memos provides a RESTful API that allows CRUD operations on memos, enabling integration with scripts, bots, or third-party applications.
Memos can be run on Linux, macOS, Windows, or any environment that supports Docker; binary installations are also available for the major OSes.
Memos is released under the MIT license, free to use, modify, and distribute with no subscription fees.
