IPLogs vs Mozilla http scanner

IPLogs scores an IP address's likelihood of being a VPN, proxy, Tor exit node, or datacenter host by combining 25+ signals -- ASN/PeeringDB classification, TCP/IP and TLS fingerprinting, RTT timing, and active probing -- into a single verdict and confidence score. A single keyless POST to /v1/check (optionally enriched with client-side signals like user-agent, timezone, and WebRTC IP) returns the verdict, a 0-1 risk score, and the matched signals with their weights, run by DigitalD.tech. There's no signup and no enforced rate limit today -- the public endpoint is explicitly fair-use, with dedicated deployments available on request for high-volume callers.

The HTTP Observatory grades a website's security headers -- CSP, HSTS, cookie flags, and more -- against Mozilla's recommended baseline, the same engine behind the long-running Mozilla Observatory scanner. The original mozilla/http-observatory Python API was shut down on 2024-10-31 when the tool moved to MDN; automated callers now POST to a v2 scan endpoint that returns a grade, score, and pass/fail counts, with a details link back to the full MDN report. It's fully public and keyless, rate-limited to one fresh scan per host per minute (cached results are returned for repeat calls within that window), and built for CI-pipeline use.
