Honest caveat, none of us have really used SurveyJS, so correct me if I'm off.
Biggest overlap is the JSON-schema idea, which is our first point here:
1. A JSON engine. The form is governed by a JSON definition that you can store in a DB, version, diff, or generate it with LLMs as a validated JSON.
2. We provide also 28 headless components (and growing) that you can style with CSS variables. We offer APIs so you can drop in Material, Shoelace, or your own components.
3. A DX typed authoring layer on top to write forms programmatically, that generates JSON. So you don't have to write it.
4. The same definition can render the UI components in React, Angular, Vue, Lit, or Vanilla JS.
5. We also have a deterministic MCP that has tools for to validate the model's output, generate JSONs or code, and ensure that the definition returned by the LLM is always valid.

But you can see that we do way more...
