Frequently asked questions

How does SmartScan detect technologies?
SmartScan fetches the page HTML, inspects script src attributes, meta tags, response headers, cookie names, and inline HTML patterns — matching them against a signature database of known technologies.
Is it free to use?
Yes — 10 scans per month are free after registration. No credit card required. For more scans, see our paid plans.
Can it detect technologies on JavaScript-heavy sites?
Yes. Switch to Dynamic rendering mode and SmartScan will fully render the page in a browser before analyzing — catching technologies that are only visible after JS executes.
How accurate is the detection?
SmartScan correctly identifies most popular technologies. Some highly customized or self-hosted setups may not match known signatures. Detection is based on public signals in the page source.
Can I check multiple websites at once?
Yes — use Bulk Scan mode (Pro plan) to process a list of URLs in one job. All tech stacks are included in the ZIP export.
