Overview
Mathesar gives PostgreSQL databases a spreadsheet-style front end, so people who are comfortable with tools like Excel or Airtable can browse, filter, edit and explore relational data without learning SQL.
The project is stewarded by the Mathesar Foundation, a US nonprofit that received a 3 million dollar grant from the Reid Hoffman Foundation in 2024, and is built to work directly against native Postgres schemas and access controls rather than a separate proprietary data layer.
Key Features
Users get an Airtable-style grid interface for viewing and editing rows, the ability to explore and link related tables, saved data explorations that can be shared with teammates, and multi-user collaboration governed by Postgres's own role-based permissions.
Because Mathesar operates directly on real Postgres tables rather than importing or syncing data into a separate store, any changes made through the interface are immediately visible to every other application already connected to that same database.
Pricing
The self-hosted edition of Mathesar is completely free and open source under a permissive license, deployable via Docker or Docker Compose on infrastructure the user controls.
Mathesar Cloud is a newer, early-beta hosted option with a free workspace tier for users who want to try the product without managing servers themselves; the Foundation has stated self-hosting will always remain a core, fully supported option.
Key Features
Spreadsheet-style data grid — Browse, sort, filter and edit Postgres table rows through an Airtable-like grid interface.
Native Postgres compatibility — Operates directly on existing Postgres schemas and tables with no proprietary data layer or migration required.
Postgres-native access control — Permissions inherit from Postgres roles, so database-level security policies carry through to the UI.
Relationship exploration — Users can link and navigate related tables to understand and edit connected data.
Saved data explorations — Queries and views can be saved and shared with collaborators for repeated use.
Self-hosted deployment — Runs via Docker or Docker Compose on a user's own infrastructure, keeping data fully under their control.
Multi-user collaboration — Multiple users can work on the same database concurrently with role-based access.
Open-source codebase — Fully open source on GitHub, allowing self-hosting, auditing and community contributions.
