NocoDB is a universal database GUI that supports multiple backends, while Mathesar is Postgres-only but deeply integrated with its native features, like using Postgres roles and privileges for access control. NocoDB also adds its own UI-level abstractions on top of database objects, whereas Mathesar directly reflects the database structure. That said, NocoDB has features Mathesar doesn’t yet support, like kanban and calendar views, forms, and more Airtable-like data types.

Baserow is more of an open-source Airtable alternative and doesn’t connect to existing databases at all—unlike Mathesar and NocoDB. It has many of the same UI-driven features as NocoDB, such as different types of views and forms, but it doesn’t function as a database interface the way Mathesar does.

Mathesar, however, has a visual query builder that allows joins and query creation directly from the UI, as well as some data modeling tools, like moving columns between tables and merging duplicate data—neither NocoDB nor Baserow offer these. Mathesar is also 100% open source, while both NocoDB and Baserow follow an open-core model with paid features.

We do want Mathesar to be competitive as an Airtable alternative over time. You can already create a database from scratch (we’re not just a GUI for existing databases), but we’d likely need more data types, views, and integrations before it can match Airtable across a broad set of use cases.

And Postgres is definitely amazingly versatile! That's one of the reasons we were comfortable focusing on it as the only supported DB backend for now.
