Notion has become the default workspace for startups and small teams — its combination of documents, databases, wikis, and project management in a single tool is unmatched in polish and breadth. But that convenience comes with trade-offs: your data lives on Notion's servers, offline support is limited, and pricing scales per seat in ways that get expensive for larger teams. AppFlowy is the open source alternative built for users who want Notion's workflow without the vendor lock-in — you can self-host it, own your data completely, and customize the application to fit your exact needs.

AppFlowy doesn't try to replicate every Notion feature. Instead, it focuses on the core experience — documents with rich block editing, kanban boards, grid databases, and a clean interface that feels familiar to Notion users. Where AppFlowy excels is in flexibility: you can run it on your own infrastructure, extend it with plugins, and ensure your team's knowledge base isn't dependent on a third-party service's pricing decisions or uptime. The trade-off is that AppFlowy's feature set is still maturing compared to Notion's years of development.

Choose Notion if you need the most polished experience right now, with extensive integrations (Slack, GitHub, Figma, etc.) and features like AI assistance built in. Choose AppFlowy if data sovereignty matters to your organization, you want to avoid per-seat SaaS pricing at scale, or you need to customize the workspace tool to fit specific workflows that Notion doesn't support natively.
