Build delightful internal tools in minutes with REST APIs

Connect any REST APIs in clicks, write queries and configure params + request body in the light-weight query editor, and bind data dynamically to a growing library of 45+ widgets from tables, charts, tabs, forms, a rich-text editor, and more. Give your end-users an easy interface to view and write records while preventing accidental data damage.

Deploy confidently to our cloud or self-host our on-prem open-source on Digital Ocean, AWS ECS, AWS AMI and more using our pre-built Docker and Kubernetes images.
