Check the tech stack of a whole domain list in one run
DomainDNA is a pay-per-result tool on Apify for long domain lists. Paste a list (or send it by API) and get one record per domain: the technologies the site runs with the evidence for each, the email provider, SPF and DMARC policy, registrar and domain age, TLS certificate expiry and security headers. Download the results as CSV, Excel or JSON. Monitor mode re-checks a list on a schedule and returns only the domains that changed.

Why teams pick DomainDNA
- One record per domain with tech stack, email provider, SPF/DMARC, domain age, TLS expiry and security headers, not tech alone.
- Evidence on every technology, so a surprising result can be checked.
- You pay only for domains that resolve; dead domains in an old list cost nothing.
- Monitor mode returns and charges only domains whose stack, mail provider, DMARC, certificate or headers changed, so a daily watch stays cheap.
- No subscription: a list of 1,000 domains is $4.
How it works
- Open DomainDNA on Apify and paste your domains, one per line.
- Run it; each domain becomes one row with stack, email security, age and TLS.
- Download CSV or Excel, or schedule monitor mode to hear only about changes.
FAQ
How much does a bulk tech lookup cost?
$0.004 per domain that resolves, so 1,000 domains cost $4. Domains that don't resolve are free.
Why not nexgendata's wappalyzer-replacement?
It charges $0.10 per detection on Apify. DomainDNA is $0.004 per domain and adds email provider, SPF/DMARC, domain age and TLS expiry in the same row.
Why not a cheaper tech-only Actor?
automation-lab's tech-stack-detector can be cheaper per URL on higher Apify plans if you only need technologies. DomainDNA costs a little more because it also returns email security, domain age, TLS and headers, with evidence.
Why not BuiltWith?
BuiltWith (from $295/month) does reverse lookups: every site that uses a tool. DomainDNA doesn't; it checks the domains you already have, per domain, with no plan.
Do I need an Apify account?
Yes, for this tool. If you'd rather pay by card and get an API key, use the DomainDNA API ($5 for 1,000 domains).
