dead-drop vs Botd
BotD is FingerprintJS's open-source, MIT-licensed JavaScript library that runs entirely in the browser to flag basic automation -- headless Chrome, PhantomJS, Selenium, and similar tools -- without any server round-trip for the detection itself. It ships as an npm package or as a CDN-hosted ES module and returns a plain detected/bot-kind result object from a single detect() call. It is free for any use with no signup; FingerprintJS separately sells a more sophisticated, paid, server-side Bot Detection API for teams that need those extra signals.
Compare →dead-drop vs Mozilla http scanner
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.
Compare →dead-drop vs National Vulnerability Database
NIST's NVD API 2.0 is the government's canonical feed of CVE records, each enriched with CVSS scores, CPE product matches, CWE weakness types, and (where applicable) CISA Known Exploited Vulnerabilities flags. It's fully public and keyless, though a free API key lifts the rolling rate limit from 5 to 50 requests per 30 seconds, and NIST recommends polling by lastModStartDate/lastModEndDate rather than re-pulling the whole dataset. The stored URL pointed at a legacy JSON-feed changelog page; corrected to the current "Start Here" developer docs for the 2.0 REST API.
Compare →dead-drop vs IPLogs
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.
