A free collection of network and security tools, built for people who just need answers.
If you want one answer — is my website okay? — start with the Website Health Check. Enter any domain and get a free report covering SSL, DNS, email, security headers, and speed, explained in plain English. Individual tools below remain available for deeper investigation.
sky-ai.my is a free, browser-based toolkit for network diagnostics and security research. It provides tools like SSL certificate checking, DNS lookups, WHOIS queries, HTTP header inspection, IP geolocation, port scanning, speed testing, reverse IP lookup, subdomain discovery, and website screenshot capture — all in one place, with no account required.
Every tool on sky-ai.my is designed for speed and simplicity. No popups, no email capture walls, no fake rate limits pushing you toward a paid tier. Enter a domain or IP, get results instantly. The interface is clean, the output is structured, and everything works on mobile.
All tool queries run in real-time. Results are generated on-the-fly and delivered directly to your browser. Nothing is stored in a database. Nothing is logged to a user profile. When you close the tab, it's gone. There are no user accounts, no tracking, and no personal data collection.
sky-ai.my is and will remain free. No sign-ups, no subscriptions, no paywalls. The goal is to provide genuinely useful tools that respect your time and your privacy.
The stack is intentionally minimal: PHP for the backend, nginx as the web server, Docker for deployment, and a vanilla JavaScript frontend with no frameworks or build tools. Less complexity means faster responses and fewer things to break.
