What is Retool: No-Code Platform for Building Internal Tools

Retool is a no-code/low-code platform that lets you build internal tools and apps by dragging and dropping components and connecting them to databases or APIs. It simplifies app creation by handling the backend logic and UI, so you can focus on your data and workflows.

How It Works

Retool works like building with digital LEGO blocks. Instead of writing code from scratch, you pick ready-made pieces like tables, buttons, and forms, then arrange them on a canvas. Each piece can connect to your data sources such as databases, APIs, or spreadsheets.

Behind the scenes, Retool handles the technical details like fetching data, updating records, and running queries. You just configure how components interact and what actions happen when users click buttons or enter information. This makes building apps faster and easier, especially for people who are not expert programmers.

Example

This example shows how you might use Retool to create a simple app that displays a list of users from a database and lets you add a new user.

plaintext

1. Drag a Table component onto the canvas.
2. Connect the Table to a database query like: SELECT * FROM users;
3. Add a Text Input component for entering a new user's name.
4. Add a Button labeled 'Add User'.
5. Set the Button's action to run a query: INSERT INTO users (name) VALUES ({{ textInput.value }});
6. Refresh the Table after the insert query runs to show the new user.

Output

A table showing all users updates to include the newly added user after clicking the 'Add User' button.

When to Use

Use Retool when you need to build internal tools quickly without deep programming skills. It is ideal for creating dashboards, admin panels, inventory systems, or customer support apps that connect to your existing data.

For example, a sales team can use Retool to track leads and update statuses, or an HR department can manage employee records. Retool saves time by avoiding custom coding and lets you adapt apps as your needs change.
