AppFlowy
Free tierThe open-source Notion alternative that keeps your data in your hands
An open-source workspace that brings docs, wikis, kanban and project tracking together. It runs fully offline and locally, and can be self-hosted with Docker so your data never leaves your hands.
Why we picked it
AppFlowy tackles the exact thing that makes Notion uneasy: who actually holds your data. It packs docs, databases, kanban and calendars into a local-first workspace that runs standalone — no internet, no sign-up needed to start — with no paywall on the core features and no ads.
Being open source, it can be fully self-hosted with Docker, so team collaboration and sync run on your own server. If you love Notion's "everything is a block" model but don't want to hand your company docs and personal notes to someone else's cloud, AppFlowy is the most mature free-and-sovereign choice today.
