Spreadsheet-like web interface for PostgreSQL that lets users of any skill level view, edit, query and collaborate on data directly.

Mathesar sits on top of an existing PostgreSQL database and presents it as something much closer to a spreadsheet. Colleagues who will never write SQL can read and change real data without waiting for a developer to build them a custom admin panel first.
There is no extra abstraction in between. Mathesar works directly with Postgres schemas, tables, primary keys, foreign keys, constraints and data types, so a relationship in the interface is a foreign key in the database, and access control uses existing Postgres roles and privileges instead of a parallel permission system. Anything else in the Postgres ecosystem keeps working alongside it.
The interface handles both data entry and light analysis.
- Table editing: view, create, update and delete records in a spreadsheet-like grid.
- Filter, sort and group: slice a table several ways without leaving the page.
- Data Explorer: build queries and joins through the UI, with no knowledge of SQL or joins assumed.
- Forms: share a link that collects submissions from anyone and saves them automatically as new records.
- Schema work: create and update schemas and tables, move columns between tables in two clicks, and use custom types for emails and URLs validated at the database level.
Installation is a Docker deployment against a new or existing Postgres database, and because it is self-hosted the data never leaves your servers. The project is in public beta, which its maintainers call stable and feature-rich enough for production, and it is developed by the Mathesar Foundation, a nonprofit committed to keeping it open source.
