Hi 👋
I'm a Senior Linux & DevOps Engineer with 14+ years of
experience managing production servers, cloud infrastructure,
and security hardening.
I built SysAdmin Tools (tools.techtransit.org) because I got
tired of paywalled DNS checkers, SSL tools that require
signup, and network diagnostic sites that make you jump
through hoops for basic information.
Every tool on this site:
✅ Queries live data directly (no cached or fake results)
✅ Requires zero signup or API key
✅ Is completely free — no premium tier
What your support funds:
🖥️ VPS hosting costs (running 24/7)
🔒 Domain renewal fees
🛠️ Time to build and maintain new tools
⚡ Keeping everything fast and ad-light
Tools available right now:
- DNS Lookup, SSL Checker, Email Health Checker
- WHOIS, SPF, DKIM, DMARC, MX Lookup
- Port Checker, Security Headers, Password Generator
- Cron Builder, .htaccess Generator, Nginx Config Generator
- SSH Config Generator, Subnet Calculator, IP Location
- And more being added regularly
Your support — even a single coffee — genuinely helps
keep this project running and free for everyone.
Thank you 🙏
