About Outline

Outline is a fast, modern knowledge base and team wiki built by a small independent team. It offers a clean Markdown-friendly editor with slash commands and real-time collaboration, collections that group nested documents with their own permissions, and quick full-text search, all with a focus on speed and simplicity. The source code is public under the Business Source License, which allows free self-hosting, and a hosted cloud version is sold by the same team.

Key features include single sign-on with Slack, Google, Microsoft Entra ID, Okta and other OIDC providers, document history and restore, templates, comments, public sharing and publishing of collections, an AI feature that answers questions from your documents, and a REST API with webhooks. Hosted plans are priced per workspace rather than per user, with flat monthly tiers based on team size bands such as up to 10 or up to 100 members, which makes it unusually affordable for teams near the top of a band.

Outline fits engineering-led companies and teams who want a fast, focused wiki, either self-hosted for data control or hosted at a predictable cost. It is a wiki only: there are no databases, task boards or project views, the template library is limited, and self-hosting requires Postgres, Redis and file storage. Notion suits teams that want docs, databases and projects in one tool, Confluence fits Atlassian-centric organisations, and Slite or Nuclino are other lightweight hosted wikis.
