Running these tools takes real resources. Servers, DNS hosting and whatnot... it all adds up. And while I do everything I can to keep costs down, even dirt-cheap hosting still costs money.

If you find the tools useful, a donation helps keep everything online, fast, and completely free of ads. It also opens the door to new tools, new locations, and better performance for everyone using the site.

To keep it as painless as possible, donations are handled through PayPal.

Thank you in advance.

/Flemming

PS: The least I can offer as a thank-you is an honorable mention, a backlink, and some SEO love. I will reach out after any donation.
