Retool
Build internal tools fast with drag-and-drop + code
About
Retool is the leading platform for building internal tools—the admin panels, dashboards, and operational interfaces that every company needs but nobody wants to build from scratch. It connects to any database (PostgreSQL, MySQL, MongoDB) or API (REST, GraphQL), provides a drag-and-drop UI builder with 100+ React components (tables, charts, forms, maps), and allows custom JavaScript and SQL for business logic—bridging the gap between no-code speed and full-code flexibility. Retool is purpose-built for engineering teams. It is not for customer-facing applications—it is for the tools your operations, support, and sales teams use internally. Pre-built integrations with Stripe, Salesforce, Zendesk, and 50+ other services enable rapid connection to existing business systems. Granular permissions control who can see and edit what, and audit logs track all changes. Pricing has a free tier for small teams. The Team plan at $10/user/month unlocks more features and users. A self-hosted option is available for enterprises. Retool is best for engineering teams at growing companies who are overwhelmed with internal tool requests. It is not a general-purpose app builder—for customer-facing applications, Bubble or WeWeb are better choices.

Pro Tips for Retool
Use drag-and-drop ui builder for rapid prototyping, then export and refine in your IDE for production—the best of both speed and control.
Build incrementally with database connectors—generate core functionality first, then iterate on design and edge cases.
Combine custom js/sql logic with version control—commit after each successful generation to create safe rollback points.
Use permissions and auth for rapid prototyping, then export and refine in your IDE for production—the best of both speed and control.
