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.
We publish how severity is assigned — live probes, impact-based priorities, no vanity score as the product — in How We Grade Website Health. That methodology is the product difference: evidence you can hand to a host or agency, not a opaque letter grade.
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.
sky-ai.my is built and maintained by an independent developer based in Malaysia, focused on practical infrastructure tooling without the bloat of enterprise SaaS dashboards. The site is actively updated — tools are patched when DNS providers change behavior, new TLS requirements emerge, or users report edge cases through [email protected].
Beyond interactive tools, we publish original guides in the Learn section — step-by-step articles on SSL, DNS propagation, email authentication, security headers, and website launch checklists. These articles are written for humans, not search engines: they explain concepts, show real failure scenarios, and link to the relevant free tools on this site.
Recent playbooks include Fix Email After a DNS Migration and the Health Check grading methodology above — content that only makes sense in the context of how this site actually probes the public internet.
Port scanning, subdomain discovery, and similar tools can be misused. We enforce rate limits and expect users to follow our Terms of Service — only test systems you own or have explicit written permission to assess. Abuse reports can be sent to [email protected].
