Appsmith

Appsmith is an open-source low-code framework for building business apps and internal tools. It ships with native Airtable integration in beta and connects to 25+ databases and APIs. The visual builder lets you create forms, tables, and workflows by dragging components and wiring them together with minimal JavaScript.

Appsmith appeals to teams and individual developers who want to build tools fast and own the code. The open-source nature means you can fork it, customize it, and self-host without vendor dependency. If you know a little JavaScript and want a low-code tool that gives you escape hatches, Appsmith is a strong pick over no-code-only platforms.
