Knowledge base software
Alternatives to Confluence
Confluence combines pages, whiteboards, databases, and Loom video messaging in one workspace for knowledge management and project collaboration. Teams can edit in real time, comment, assign tasks, and connect documentation with Jira. Rovo reshapes content into timelines, charts, maps, slides, and prototypes, while integrations and Marketplace apps extend the workspace. It supports custom domains, single sign-on, version history, analytics, public view-only links, and cloud or self-managed deployment. The free plan allows up to 10 users, 2 GB of file storage, three active whiteboards per user, and 50 automation steps per subscription each month; paid plans start at $5.42/user/mo with a 7-day trial.

Choosing instead of Confluence
An alternative may suit you better when its platform range, deployment approach, publishing model, or allowance fits your team more closely. Confluence runs on Android, iOS, web, and self-hosted infrastructure, but its free tier has defined user, storage, whiteboard, and automation ceilings. Compare collaborative editing, external publishing, custom domains, SSO, version history, analytics, structured content, and AI capabilities. Also weigh whether you need cloud software or infrastructure you control, and whether the alternative’s free or paid starting point matches your budget.
