Developers can connect to a variety of data sources, including databases, APIs, and third-party services, using the platform’s visual drag-and-drop interface to build custom user interfaces. Retool’s wide collection of pre-built UI components and integrations, which may be quickly modified to match a particular use case, is one of its primary strengths. Data tables, forms, charts, and maps are among these components, along with interfaces with well-known programs like Slack, Twilio, and Stripe.
