FilterLists vs PhishStats

FilterLists is Collin Barrett's independent, actively-maintained directory of filter and host lists used by adblockers, firewalls, and DNS sinkholes to block ads, trackers, malware, and other unwanted content. Its ASP.NET Core REST API serves the same catalog that powers the site -- filter lists, the domains/URLs they target, licenses, and maintainer info -- with an interactive Swagger UI for exploring the schema before writing a query. The API and site are fully free and keyless, open-sourced on GitHub with commits as recent as this week. The API lives entirely on a separate `api.filterlists.com` host -- the intuitive REST paths on the main `filterlists.com` domain just return the site's own SPA shell.

PhishStats crowdsources and republishes a running feed of phishing URLs, screenshots, and detection metadata, giving anyone a free real-time phishing blocklist to query or download. The REST API — now served from api.phishstats.info after moving off its old port-based endpoint — supports complex filter queries against the phishing database and returns JSON records ready to stream into an existing security stack. Anonymous lookups are capped at 50 requests/day per IP; a free registered key raises that to 150/day, with paid tiers for higher volume.
