// EDITOR'S TAKE
AppSmith and ToolJet are the direct equivalents, both drag-and-drop UI over your own SQL and REST sources, with AppSmith the more proven at scale and ToolJet the quicker to get running. Windmill inverts the model by generating UIs from scripts, which suits engineers who would rather write TypeScript or Python than click through a canvas, and refine is a React framework rather than a builder.
