Tech Stack & Email Provider Detector
Pricing
from $3.00 / 1,000 domain checkeds
Find the CMS, ecommerce platform, analytics, marketing tools, payment providers and email provider (Google Workspace, Microsoft 365...) behind any list of websites. Clean table output. $3 per 1,000 websites, only pay for sites analyzed.
Domains or URLs to analyse, e.g. example.com or https://www.example.com. Paths are ignored; duplicates are removed.
Besides the homepage, fetch up to this many same-site links (prefers /pricing, /about, /shop ...). Hard cap: 3 pages per domain.
Look up MX and TXT records to identify the email provider, SPF-authorised sending services and domain-verification tokens (only the service name is reported).
How many domains are processed in parallel. Pages within one domain are always fetched sequentially.
Timeout for each HTTP request and DNS lookup.
Compare with the previous run's results (stored in the named key-value store 'fieldfeed-techstack-state') and output only domains whose technology set, email provider or SPF services changed, with added/removed lists. Domains seen for the first time count as changed.
