Outline vs Notion: Pick Your Knowledge Base
Outline and Notion both want to be the place your team's knowledge lives, but they make very different bets. Notion ships as a polished all-in-one workspace combining docs, databases, and lightweight project management. Outline is an open-source, focused team wiki that you can self-host or use as a managed cloud product. The choice usually comes down to how much flexibility you want versus how much control you need over your data.
Outline
View detailsOutline is an open-source team wiki and knowledge base focused on fast docs, clean structure, and the option to self-host on your own infrastructure.
Key Features

- Self-hostable via Docker for full data ownership

- Built-in search across the whole knowledge base
- Slack and API integrations for cross-tool linking
Pros
- + Self-hosting means your team's docs never leave your servers
- + Genuinely fast, with load times that feel native, not laggy like some all-in-one tools
- + Open source license lets you fork or audit if you ever need to
Cons
- - No databases, no kanban, no project management. It's a wiki, not a workspace
- - Self-hosting means you own the upgrades and backups too

The Verdict
Outline is the right call if your team needs a focused wiki, cares about data ownership, or wants the option to self-host. Notion is the right call if you want one tool to do everything and you're fine trading data sovereignty for that breadth. Teams in regulated industries lean Outline. Teams that want speed-to-value lean Notion.
