Notabase is suited to people who build knowledge by connecting notes rather than keeping isolated documents. Notes can link to one another, be tagged, nested, and viewed in a graph; stacked pages help compare related material. The official site says the product is open source and can be self-hosted. Its hosted Basic plan is free but limited to 10 notes; Pro costs $80/year, shown as $6.67/month billed annually, and adds unlimited notes and publishing. Self-hosting shifts deployment and maintenance to the user.
