About Outline

Outline is a knowledge base platform designed for teams to create, collaborate on, and organize documentation. It combines a clean, distraction-free writing experience with powerful search and editing features. Built with React and Node.js, it offers real-time collaboration, markdown support, and integrations with popular tools like Slack and GitLab.

Outline supports self-hosting on Linux servers via Docker, with extensive customization options. The open-source version is MIT licensed and free to use. For teams that prefer a managed solution, Outline offers a hosted cloud version with additional features like SSO and priority support. It can be deployed on any server with Docker, making it flexible for various hosting environments.

Ideal for small to large teams needing a private wiki, Outline is used by companies like Raycast and Vercel. Its clean interface and fast performance make it a popular alternative to Confluence and Notion. The project is actively maintained by Outline Inc., with a strong community contributing to its development.
