// EDITOR'S TAKE
Budibase comes closest to the full-stack promise, bringing its own database, users and deployment in one product, while ToolJet and AppSmith assume you already have APIs and databases and just want a UI over them. NocoBase suits data-model-driven internal systems, and refine is not low-code at all, it is a React framework, so you own the code but write it yourself.
