Your PostgreSQL database, like a spreadsheet
A spreadsheet interface powered by Mathesar, installed and maintained by DINAO. Visualize, create, and edit your PostgreSQL data without writing SQL — your data stays on our French servers.
What is Mathesar?
Mathesar is an open-source web interface that connects directly to an existing PostgreSQL database and exposes it as a spreadsheet : you can view, create, edit, and delete records without writing a single line of SQL. This makes your data accessible to non-developers (inventory, lightweight CRM, grant tracking, customer support) while remaining a true relational database.
It includes a visual query builder, the Data Explorer, which allows joins and aggregations and saves results as 'Explorations', as well as a comprehensive modeling tool (create/modify tables and schemas, foreign keys, column migrations, custom types validated at the database level such as emails or URLs). Access control relies natively on PostgreSQL roles and permissions.
Technically, Mathesar is built on Django/Python (with PL/pgSQL) on the server side and Svelte/TypeScript on the interface side. It deploys via Docker in minutes and is maintained by a non-profit foundation committed to keeping it open-source and self-hostable in perpetuity.

Technical details
You might be wondering…
Do I need to know how to write SQL?
No. Mathesar exposes your PostgreSQL database as a spreadsheet : viewing, editing, and even queries (via the Data Explorer) are done without writing SQL. A technical team can always work directly in the database.
Can Mathesar connect to my existing database?
Yes. That's its main purpose : it connects to an existing PostgreSQL database and exposes it as-is, without copying or moving your data.
How do access rights work?
Mathesar natively relies on PostgreSQL roles and permissions (database-level RBAC), table by table — these are not rights added on top.
Where is my data?
In your PostgreSQL database hosted by DINAO in France. It never leaves your server and remains exportable.
Is the project sustainable?
Yes. Mathesar is maintained by a non-profit foundation committed to keeping it open-source and self-hostable in the long term.
