I built CyberKit because I was frustrated with everyday security tools: they are either packed with intrusive ads, bloated, or needlessly transmit sensitive payloads (like JWTs and internal network IPs) to third-party servers. CyberKit solves this with a strict zero-backend policy. Everything is computed entirely within your browser using modern Web APIs. No accounts, no paywalls, and no tracking. Current toolkit includes: - CVSS v4.0 and v3.1 calculators - Client-side JWT decoding and debugging - CIDR/Subnet calculations - Hash generators & multi-decoders Would love to hear your thoughts, feedback, and what specific security utilities you'd like to see added next!
