Mathesar is an open-source tool that provides an intuitive spreadsheet-like interface for working with PostgreSQL data. It allows users of all technical skill levels to view, edit, query, and collaborate on data directly - without the need to write SQL queries. Mathesar is self-hosted and uses PostgreSQL’s native access control mechanisms.

Why You Need Mathesar
Working with a PostgreSQL database often requires SQL knowledge and administrative skills. However, in many organizations, data is handled not only by developers but also by analysts, managers, and specialists without programming experience.
Mathesar solves this problem by providing an easy-to-use visual interface similar to familiar spreadsheets, but with the full power of PostgreSQL behind it.
It helps you:
- edit data without using SQL queries,
- create relationships between tables through visual elements,
- filter, sort, and group data,
- collaborate on the database through a web interface.
This makes Mathesar an ideal solution for small teams and organizations that want to simplify database interaction without losing control or security.
How Mathesar Works
Mathesar can be installed locally or on a server and connects to an existing PostgreSQL database. Once connected, users gain access to their data through a web interface where each table is presented as an interactive spreadsheet — similar to Excel or Google Sheets.
Key features include:
- Data is stored directly in PostgreSQL - with no intermediate layers.
- Uses standard PostgreSQL access control mechanisms.
- Supports data import and export in popular formats (CSV, JSON, etc.).
- Allows visual query building without writing code.
