I like Wappalyzer because it has a lot of filter options and provides contact information when available. This is really helpful because I can filter out companies I already have data on, so I don't get information I don't need. It's also been beneficial in identifying my target market. I appreciate that their support responded really fast when I had an issue with my account. Review collected by and hosted on G2.com.

I had an issue where my account didn't recognize that I had paid, so it wouldn't let me export the list on my own. I had to email support, but they responded really fast and emailed me the list that way. Review collected by and hosted on G2.com.
