How it works
The actor analyzes multiple signals to identify technologies:
- HTTP Headers —
Server,X-Powered-By, CDN headers, platform-specific headers - HTML Content — Meta generator tags, framework-specific DOM markers, class patterns
- Script Sources — JavaScript library CDN URLs, inline script patterns
- CSS References — Framework stylesheet URLs
- Cookies — Session cookie names that reveal server-side technology
Each detection includes a confidence level (high or medium) and the source of detection.
Output format
Each result includes:
url— The analyzed URLtechnologyCount— Total technologies foundtechnologies— Array of detected technologies, each with:name— Technology name (e.g., "React")category— Category (e.g., "JavaScript Framework")version— Version if detected (e.g., "18.2.0")confidence— Detection confidence ("high" or "medium")source— How it was detected (e.g., "script src", "HTTP header")
categories— Technologies grouped by categorysummary— Quick highlights

FAQ
Q: Do I need an API key? A: No. The actor works with any public website. Just enter a URL.
Q: How many URLs can I analyze at once? A: Up to 100 URLs per run.
Q: Does it detect version numbers? A: Yes, when available. Version detection works for many JavaScript libraries and frameworks loaded via CDN.
Q: What's the difference between "high" and "medium" confidence? A: "High" means the technology was identified by a definitive marker (specific header, CDN URL). "Medium" means it was found via pattern matching in HTML or inline scripts, which may occasionally produce false positives.
Q: Is this legal? A: Yes. The actor only reads publicly available HTTP headers and HTML content — the same information your browser sees when visiting a website.
Q: How does this compare to Wappalyzer or BuiltWith? A: Similar concept, but pay-per-use pricing instead of monthly subscriptions. Ideal for one-off checks or integration into automated workflows.
Q: Can it detect server-side technologies?
A: Partially. Server-side tech is detected when it reveals itself through HTTP headers (e.g., X-Powered-By: PHP) or cookies (e.g., PHPSESSID). Technologies that don't expose any client-side signals cannot be detected.
Q: Does it work with JavaScript-heavy single-page apps? A: Yes. It detects React, Vue, Angular, and Svelte through their DOM markers, even on SPAs. However, it uses static HTML analysis — it does not execute JavaScript.
