Keep useful technology tools free.
Our free checkers help people learn about Minecraft servers, public website security, DNS, browser visibility and online privacy. You never need to pay, donate or create an account to use them.
Support the work behind the tools
Contributions help Savana Security invest in site hosting, diagnostic provider capacity, maintenance, security testing, accessibility improvements and new educational features.
This opens Cash App, where you choose any amount and review the recipient before sending. Contributions are voluntary and do not buy services, subscriptions, priority support or access to tools. There is no donation goal or amount you must meet.
Savana Security is a for-profit business, not a registered charity or 501(c)(3) nonprofit. These are optional contributions to support our work, not tax-deductible charitable donations. No charitable receipt will be issued. Please verify the Cash App recipient shown in Cash App before sending and never send money you cannot afford to give.
Payments through Cash App are subject to its terms, and we must ensure the receiving account is permitted to accept business-related contributions. For questions or payment problems, contact savanasecurity@gmail.com.

Prefer not to contribute? Sharing a useful tool with someone who needs it also helps. The tools stay free regardless.
Businesses can help without interruptive ads
We also welcome carefully vetted educational and technology sponsors. Sponsor messages would be limited, labeled, and never shown inside diagnostic results or account-sensitive workflows.
