What it is

Outline is a fast, open-source knowledge base with a modern block editor, collections, real-time collaboration and strong Slack integration, available as a hosted cloud service or self-hosted from its public source code. Cloud pricing is a flat fee per team-size tier ($10 per month for up to 10 members) rather than per seat, which makes it unusually cheap for small teams. Self-hosting requires an external OIDC/OAuth identity provider and careful configuration, and the hosted service processes data primarily in the United States.

Standout capability

A genuinely open-source wiki with a Notion-quality editor that you can run yourself or pay a flat $10 a month to host.

Community sentiment

What people praise

Self-hosters see Outline as the mature, stable open-source wiki with a large community, a polished block editor with slash commands and real-time collaboration, and a hosted option to fall back on.

What people complain about

The main gripes are the fiddly self-hosted setup that demands an external identity provider and exact configuration values, plus documentation that leans towards the hosted product.
