Tech stack lookup API

Sales and research teams sort leads by the technology they use. Give a list of domains and get their technologies by category, with hosting, email provider and security grade.

What you get

Python example

from apify_client import ApifyClient  # pip install apify-client

client = ApifyClient("<YOUR_APIFY_TOKEN>")
run = client.actor("fguiraud/website-tech-dns-whois-ssl").call(run_input={
    "domains": [
        "wordpress.org",
        "apify.com"
    ],
    "checks": [
        "tech",
        "hosting",
        "dns"
    ]
})

for item in client.dataset(run["defaultDatasetId"]).iterate_items():
    print(item["domain"], item.get("technologyNames"))

No Python? Open the Actor page, paste your input in the form and press Start; results export to JSON, CSV or Excel.

FAQ

How is technology detected?

From the home page HTML, headers, cookies, scripts and DNS records.

Can an AI agent use it?

Yes. It is an MCP server at https://mcp.apify.com/?tools=fguiraud/website-tech-dns-whois-ssl (listed in the official MCP registry), and there is an agent skill for Claude Code, Codex and Cursor. Field-name guesses such as url or urls are accepted.
