FAQ
How is it different from the Wappalyzer extension?
It runs on a whole list of domains at once and returns structured rows you can filter and export, plus emails and social profiles.
Can I find sites using one tool but not another?
Yes. List technologies under must use and must not use, for example shopify but not klaviyo.
Does it need a browser?
No. It reads pages directly and retries blocked sites through residential proxies when that option is on.
Is it legal to scrape websites?
The scraper collects only publicly visible data from websites, without logging in. Whether your use is lawful depends on your country and purpose: respect local law and the site's terms, and avoid collecting or storing personal data you don't need.
How do I get the data into my app or spreadsheet?
Run it from the Apify API or the Python and JavaScript clients, or connect it to Make, n8n, Zapier or Google Sheets. Results export to JSON, CSV or Excel.
