Retool makes it easy to build apps on top of Slack. Join data across multiple Databases and APIs. Manage access to your app with granular permissions.

Connecting Retool to Slack takes just a few minutes, and lets you build user interfaces quickly on top of your data.

Retool supports both reading and writing from Slack. Combine Slack data with other datasources, including your own databases (e.g. Postgres), and other APIs (e.g. Stripe or Firebase), into a single frontend.

Retool's library of 50+ drag and drop components – think tables, buttons, text inputs, lets you build your front-end in no time. Connect components to requests to your Slack data via Retool's query GUI, and you've got yourself a working tool in no time.
