Outline is a realtime team knowledge base. Official hosts we opened on 2026-10-24: outline/outline (41,042 stars, 3,635 forks, created 2016-05-22, last push 2026-10-24T01:48:16Z, default branch main), LICENSE (Business Source License 1.1), release v1.12.0 (2026-10-23), and getoutline.com. Language field: TypeScript. README last line: “Outline is BSL 1.1 licensed.”
It is listed on Notion alternatives as the team-wiki row next to AppFlowy and AFFiNE. That mapping is editorial. BSL 1.1 is not an OSI open-source license on the file we opened. We do not pretend it is still BSD-3-Clause.
The README (opened 2026-10-24): “fast, collaborative, knowledge base” built with React and Node.js. Production self-host docs: docs.getoutline.com/s/hosting. Hosted getoutline.com is a separate SKU. Those labels are copied.
