Knack

Knack centers around defining a database structure visually, then generating forms, tables, charts, and custom pages on top of that schema. You control user access by role and can set field-level permissions so different teams see and edit only what they need. The result is a self-contained application that lives on Knack's infrastructure with no code to deploy.

The free tier gives you a small app to try the workflow, and paid plans scale up with your database size and user count. Knack appeals to small teams and organizations without development staff who want a professional-looking internal application without writing code.
