I need to make a webscraper interface similar to Octoparse

I want to integrate into my system a webscraper interface, whereby my customers determine what to scrape (usually their own website).

They don't need to be running scrapes or seeing the data, but they should set up 'what to scrape', and then we take it from there.

If you have suggestions or white label software i'm also open to that.

Hope that makes sense! Thanks.
