Is Outline free and open source?
Not by the OSI definition. Outline is source-available rather than open source: its code is public under the BSL 1.1, which is not an OSI-approved open-source license. The Business Source License lets you read, modify and self-host the code, but production use is limited to what its Additional Use Grant allows, and each release converts to an open-source license after a set date. Check the license in the repository before using it commercially.
Can I run Outline with Docker?
Yes. Outline provides a Docker image, so you can run it on any Linux server with Docker and Docker Compose installed. Our step-by-step deploy guide covers the Compose file, HTTPS and backups.
