SurveyJS
Open-Source JSON Form Builder to Create Dynamic Forms Right in Your App. With SurveyJS form UI libraries, you can build and style forms in a fully-integrated drag & drop form builder, render them in your JS app, and store form submission data in any backend, inc. PHP, ASP.NET Core, and Node.js.
I know it's an annoying answer, but it depends on your application. The only true way to know is to test it using a load tester like artillery. Measuring performance is a fundamental part of any optimisation (otherwise how do you know?), so it's a great idea to be using tools like this anyway.
