FAQ

How much does Tech Stack Detector like Wappalyzer cost?

$0.0025 per website analyzed on the Apify Free plan ($2.50 per 1,000), billed per result by Apify with no subscription. Plus $0.0001 per actor start. Higher Apify plans get the discounted tiers shown in the pricing table. You can cap any run with a maximum cost.

How is this different from Wappalyzer or BuiltWith?

Wappalyzer's and BuiltWith's APIs are sold as monthly subscriptions. This Actor uses the same open fingerprint format as Wappalyzer, so detections and names match what you know. You pay per website, with no subscription. Unlike BuiltWith it checks the live website at run time instead of a historical database, so results are current but don't include past technologies.

Why wasn't technology X detected?

The Actor doesn't run a headless browser, so tools that are only injected later by JavaScript (some chat widgets and pixels loaded through a tag manager) can be missed. It still finds them when they show up in the HTML, script URLs, inline scripts, cookies, headers or DNS. Setting Pages per website to 2-3 catches tools that only load on some pages. If something is consistently missing, tell us in the Issues tab.

How accurate is it? What does confidence mean?

Each fingerprint carries a confidence (usually 100). The confidences of all matching signals are added up, to a maximum of 100. Minimum confidence 50 (the default) hides weak single-signal guesses. detectedBy shows how each technology was found (headers, scriptSrc, dom, dns, implied...), so you can judge for yourself.

Can I find all websites using a technology (e.g. every Shopify store)?

This Actor checks the websites you provide. It doesn't search the whole web. Feed it a list (from Google Maps Scraper, a CRM export or a domain list) and use Only websites using to keep only the matches. You only pay for matches.

Why does a website list tools like Zoom, Figma, Atlassian or OpenAI?

Those come from the domain's DNS TXT records. Companies add a verification record when they connect their domain to a SaaS account, so it's a solid sign that the company uses that tool, even though it doesn't run on the website. detectedBy: ["dns"] marks them, and dnsRecords.txtVerifications lists the raw verifications. Turn off DNS & TLS checks if you only want what runs on the website itself.

Does it give versions?

Yes, when the site exposes them (meta generator tags, script URLs like jquery-3.7.1.min.js, headers). version is null otherwise.
