About
Stackray is a self-hosted, open-source alternative to BuiltWith that scans a domain or URL to detect its technology stack, frameworks, business tools, subdomains, and DNS records, adding OSINT detail that goes beyond typical stack-detection tools. Teams can deploy their own instance to schedule recurring scans, get alerts via Resend email or Slack, invite teammates, and issue API keys for programmatic use.
Why it made the leaderboard
It gives teams a self-hosted way to monitor a domain's technology footprint and get alerted to changes, useful for both competitive research and security recon.
