GUI for building apps on PostgreSQL
Easily connect to PostgreSQL and get right to building

Easily connect to PostgreSQL and get right to building

Retool connects directly to your PostgreSQL database (via a connection string or regular credentials) and lets you run raw SQL (or issue commands via a GUI) to manage the data in your PostgreSQL tables. For example, you can render users from Postgres into a table and add a button that, when clicked, runs an SQL query and marks that user as approved.

The PostgreSQL GUI you’ve always wanted

The PostgreSQL GUI you’ve always wanted

Query your Postgres data via raw SQL, or use Retool's GUI wrapper to safely write, update, and delete without accidentally dropping tables. You can also inspect your schema, save and share queries, and run ad hoc analyses quickly. Pull queries into a text or table component for easy reference and inspection.

Build faster with 50+ drag-and-drop components

Build faster with 50+ drag-and-drop components

Retool gives you a library of 100+ components to quickly build a frontend UI for your app with out-of-the-box components like tables, buttons, text inputs, and much more. Read, write, and update your PostgreSQL data with our code editor in minutes instead of hours.

Retool provides the building blocks for any internal tool

Whether you're building a basic CRUD interface or using our PostgreSQL IDE to build frontend dashboards, internal tools have the same building blocks: tables, text boxes, drop-downs, etc. Retool gives you a simple way to connect these building blocks with PostgreSQL (and dozens of other [data sources](https://retool.com/integrations/ "Retool Integrations")) so you can build and ship internal tools in hours, not days.
