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 recently removed Google Analytics from my websites and set up the self-hosted umami (https://umami.is/) analytics. One of the best things about it is how fast it opens, while GA is so laggy.
I'm a happy Plausible (https://plausible.io/) paying user.
Simple to use (few features compared to GA, but exactly those I need), respects privacy, and has fair pricing.
