SeekYou – unified host intelligence across 15 sources, runs free on Cloudflare.
- Built a tool that takes any IP, domain, or ASN and queries 15 sources in parallel: open ports, CVEs, BGP, RDAP, cert history, passive DNS, 5 threat feeds, exposed buckets, Wayback snapshots — all in one report.
- 4-layer parallel execution (total time ≈ slowest source, not sum of all).
- KV caching per source, circuit breakers, per-IP rate limiting.
- Typed diff engine — get alerted when ports open, CVEs appear, or certs expire on monitored hosts.
- Runs entirely on Cloudflare free tier (~5k lookups/day).
