# Mathesar Mathesar is a web application that makes working with PostgreSQL databases both simple and powerful. It empowers users of all technical skill levels to view, edit, query, and collaborate on data with a familiar spreadsheet-like interface, with no code needed. It’s self hosted, can be deployed in minutes, and works directly with PostgreSQL databases, schemas, and tables without extra abstractions. The project is 100% open source and maintained by Mathesar Foundation, a 501(c)(3) nonprofit. Mathesar is as scalable as Postgres and supports any size or complexity of data, making it ideal for workflows involving production databases. It requires minimal setup, and integrates into your existing infrastructure. Because Mathesar is self-hosted, your data never leaves your servers, and access control based on Postgres roles and privileges keeps your database secure without adding unnecessary risk. **Table of Contents** - [Status](#status) - [Install Mathesar](#install-mathesar) - [Join our community](#join-our-community) - [Contribute to Mathesar](#contribute-to-mathesar) - [Features](#features) - [Screenshots](#screenshots) - [Connecting a database](#connecting-a-database) - [Adding collaborators](#adding-collaborators) - [Viewing a Postgres schema](#viewing-a-postgres-schema) - [Working with tables](#working-with-tables) - [Finding a nested record](#finding-a-nested-record) - [Linking two tables together](#linking-two-tables-together) - [Managing table permissions](#managing-table-permissions) - [Viewing a single record with related records](#viewing-a-single-record-with-related-records) - [Building a form](#building-a-form) - [Filling out a form](#filling-out-a-form) - [Viewing an Exploration (query result)](#viewing-an-exploration-query-result) - [Building an Exploration (query)](#building-an-exploration-query) - [Disconnecting a database](#disconnecting-a-database) - [Mathesar in action](#mathesar-in-action) - [Our motivation](#our-motivation) - [Bugs and troubleshooting](#bugs-and-troubleshooting) - [License](#license) ## Status - [x] **Public Alpha**: You can install and deploy Mathesar on your server.
