Outline
Your team’s knowledge base.
Overview
Outline is an open-source, team knowledge base and wiki that can be self-hosted or used as a cloud service. It is built for speed and collaboration, featuring a clean, Markdown-based editor, real-time editing, and a structured hierarchy. It requires a third-party authentication provider (like Slack, Google, or SAML) for user management, which integrates it tightly into a company's existing identity system. It's often seen as a modern, open-source alternative to Confluence.
