A fast and simple IDE for Cassandra
Retool gives you a simple integrated development environment (IDE) to quickly build internal applications on top of your Cassandra data.

IDE for Cassandra
Retool’s simple IDE for Cassandra lets you write queries and mutations, graphically insert variables and arguments, and add headers too.

Connect to your Cassandra server in minutes
Retool connects directly to your Cassandra 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 Cassandra tables. For example, you can render users from Cassandra into a Table component and add a button that, when clicked, runs an SQL query and marks that user as approved.

Build powerful CRUD apps
Retool gives you the components you need to build great tools out of the box: tables, buttons, text inputs, and much more. Read, write, and update data from your Cassandra database in minutes, not hours.
From startups to Fortune 500s, the world's most effective teams use Retool to build custom business software. Our customers↗
