Comprar SysAdmin Tools un café

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 🙏
