SniffCat is a privacy-focused IP abuse database and OSINT threat-intelligence platform built by Polish developer Sefinek, positioned as a community-moderated AbuseIPDB alternative. Sysadmins, hosting providers, ISPs and security researchers report malicious IP addresses against a published 27-term abuse-category vocabulary, and consume the resulting reputation data through a free, versioned REST API at api.sniffcat.com: abuse-confidence lookups, per-IP report history, and score-ordered blocklist feeds in JSON or plain text for direct firewall ingestion. Entitlement is role-based rather than paid, with published daily quotas per operation and trust levels that weight how much each reporter moves an IP's score. The platform is in Early Access / open beta and publishes no machine-readable contract.
