AppFlowy

Notion is wonderful right up until you remember that everything you've ever written lives on someone else's servers. AppFlowy is the open-source answer to that unease: an AI workspace for notes, wikis and projects that promises you can 'achieve more without losing control of your data.'

One workspace, many shapes

AppFlowy integrates projects, wikis and team collaboration into a single platform, and like the best of this category it's built on flexible building blocks. You organize and visualize information through custom views, blocks and properties, so the same underlying data can appear as a doc, a board, a table or whatever fits the task. If you've used Notion, the mental model will feel instantly familiar — just open, and yours.

AI that can run locally

AppFlowy bakes in AI assistance for answering questions, improving your writing and auto-filling databases. The standout twist is that you can run local AI models directly on your own machine — so you get modern AI help without shipping your private notes off to a third-party model. For anyone who's nervous about feeding sensitive work into a cloud AI, that local-first option is a genuine differentiator.

Own your data, literally

This is AppFlowy's whole reason for being. It's fully open source, works offline, and can be self-hosted anywhere, so there's no vendor lock-in and no anxiety about a company changing its terms or vanishing with your knowledge base. Your workspace is portable and genuinely yours in a way closed tools can never quite match.

Customization without limits

Because it's open source, AppFlowy is endlessly tweakable — a community continually extends it, and technical teams can adapt it to their exact needs. It's the difference between renting a workspace and owning one you can remodel.

Who it's for

AppFlowy suits teams and individuals who prioritize data privacy, customization and collaborative workspaces — anyone looking for a Notion-style tool that doesn't require handing over their information. Privacy-conscious professionals, developers and self-hosting enthusiasts feel especially at home.

Pricing

AppFlowy is freemium with a free tier, and because it's open source you can also self-host it at no software cost. That means you can get a capable, private workspace running without paying a subscription at all — a rare thing in this category.

Bottom line: AppFlowy is the open-source, privacy-first workspace for people who love what Notion does but want to own their data — customizable, self-hostable, and even able to run AI locally.
