Alternatives to Outline
Fast, beautiful team knowledge base
Outline ranks #1 of 9 in Team wikis, with an Alt Score of 100. It is licensed under BSL-1.1, open source with paid hosting from $10/month and available on Web and macOS. 12 of 12 checklist rows are verified against a public source.
Teams and organizations that need a shared, searchable home for internal documentation instead of scattered docs and chat threads — from small teams on the cloud plan to enterprises requiring self-hosted, on-premises deployment.
A fast Markdown-based editor with slash commands and interactive embeds, real-time multiplayer editing with comments and threaded discussion, and instant workspace-wide search with AI-assisted question answering across documents. Granular permissions (read/write, groups, guest access) and public link sharing control who sees what, and 20+ integrations (including Slack) plus an open API connect Outline to the rest of your toolchain.
Documents are organized into collections (nested hierarchies covering a team, project, or topic), created and edited in Outline's editor, and found again via full-text search or AI-assisted Q&A. Access is controlled per collection or document through permissions and sharing links, and the app runs either as Outline's hosted cloud service or as a self-hosted instance on your own infrastructure.
