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.
We published a repository and blog post about distributed crawling in Python. It is a bit more complicated than what we've seen so far. It uses external software (Celery for asynchronous task queue and Redis as the database).
In some cases, you won't find the info because it is not there on the first load, for example, in Angular.io. No problem, headless browsers come in handy for those cases. Or XHR scraping as shown above for Auction.
