# Skuuy Tools > Skuuy Tools (skuuy.com) is a free, open-source privacy and security toolkit. > It provides browser-based network diagnostics, authentication, and anonymity > utilities. All tools are free forever with no account required. Cryptographic > operations run client-side; the service follows a zero-log policy. ## Live Tools - [Skuuy IP & Leak Intelligence](https://ip.skuuy.com): Shows your public IPv4/IPv6 address, geolocation, ASN, and detects WebRTC STUN leaks and DNS leaks. Includes IPv4 CIDR subnet calculator. API: https://ip.skuuy.com/api/myip - [Skuuy 2FA Authenticator](https://2fa.skuuy.com): Browser-based TOTP (RFC 6238) code generator compatible with Google Authenticator and Authy. Scans QR codes via webcam, image upload, or clipboard. Optional multi-account vault encrypted with AES-GCM 256-bit and PBKDF2 (100,000 rounds). Secret keys never leave the user's device. - [Skuuy Temp Mail & OTP Suite](https://mail.skuuy.com): Disposable temporary email inbox for sign-ups and verifications. Auto-extracts 4-8 digit OTP codes and password-reset links. Inboxes self-destruct after 30 minutes. - [Skuuy Free Proxy & SOCKS Hub](https://proxy.skuuy.com): Aggregator of 50,000+ free public HTTP, HTTPS, SOCKS4, and SOCKS5 proxies across 150+ countries, refreshed every 30 minutes via automated cron pipelines. Filter by protocol, anonymity tier (Elite L1, Anonymous L2, Transparent L3), and latency. Browser-based speed testing and export to Clash, Sing-box, cURL, and Python configs. API: https://proxy.skuuy.com/api/proxies ## Roadmap (Q4 2026) - [Skuuy DNS Propagation Matrix](https://dns.skuuy.com): Check A, AAAA, CNAME, MX, TXT, and NS record propagation across 30+ global locations, with DNSSEC validation. - [Skuuy Edge Speedtest](https://speed.skuuy.com): Multi-region ping, jitter, packet loss, and throughput test against Cloudflare edge locations. - [Skuuy HTTP Header & SSL Probe](https://headers.skuuy.com): Inspect security headers (HSTS, CSP, X-Frame-Options), trace redirect chains, and audit TLS certificate expiry. - [Skuuy Port & Firewall Probe](https://ports.skuuy.com): Check exposure of common ports (SSH 22, HTTP 80, HTTPS 443, MySQL 3306, Redis 6379, WireGuard 51820) and diagnose firewall/NAT traversal. ## Key Facts - Pricing: 100% free forever. No paywalls, no premium tiers, no account needed. Funded by non-intrusive advertising. - Privacy: Zero-knowledge architecture. 2FA secrets and cryptographic operations execute in browser memory only. No IP addresses, queries, or tokens are stored permanently. Temporary data (e.g. temp-mail inboxes) is purged after 30 minutes. - Infrastructure: Serverless edge deployment via Cloudflare. - Developer APIs: CORS-enabled JSON endpoints for IP geolocation and proxy lists. Responsible, rate-limited use is encouraged. ## Guides and Documentation - [Proxies vs VPNs vs Tor: Evaluating Security, Anonymity Tiers, and Latency Overhead](https://skuuy.com): Technical comparison of forward proxies (Layer 5/7), VPN tunneling (Layer 3), and Tor onion routing, including OSI-layer differences and latency trade-offs. - [Understanding WebRTC Leaks](https://ip.skuuy.com): How WebRTC STUN requests can expose a real IP address behind a VPN or proxy, and how to mitigate it in Firefox (media.peerconnection.enabled) and Chromium browsers. - [The Fundamentals of TOTP](https://2fa.skuuy.com): Explains RFC 6238 time-based one-time passwords: shared secrets, 30-second time steps, HMAC-SHA1/SHA256 generation, and why TOTP is safer than SMS 2FA. ## Site - [Home](https://skuuy.com) - [All Tools](https://skuuy.com/tools) - [About](https://skuuy.com/about) - [Contact](https://skuuy.com/contact) - [Privacy Policy](https://skuuy.com/privacy-policy) - [Terms of Service](https://skuuy.com/terms-of-service)
