Can you tell me where I can sign up for a free domain at this moment? Or maybe a third tier one.

Thanks ahead of time.

Getting a free domain might not always be the easiest task, but there are definitely options out there. First of all, it's importent to understand that many registrars provide free domains as part of their web hosting packages.

One popular choice is Wix. They offer a free plan where you can get a subdomain. It's not a full domain, of course, but something like yourname.wixsite.com. If you want a more proper domain, you usually have to "pay up". Another platform to consider is WordPress.com. They also give you a free subdomain, like yourname.wordpress.com, which can be beneficial for a blog or portfolio.

If you are looking for third-tier domains, such as those ending in .tk, .ml, .ga, .cf, and .gq, Freenom has the best offerings. They allow you to register these domains for free. Just keep in mind that the free domains have limitations and may not give you the same level of credibility as a paid domain.

It's also worth to mention that some other hosting providers like InfinityFree or 000webhost offer free hosting and may offer options for free subdomains as well, plus easy one-click apps to get your site up and running quickly.
If you want a genuine domain, you might ended up paying a small fee, but if you are okay with a subdomain or a third-tier domain, then there are several providers out there you can explore. Just be sure to read their terms and conditions, you don't want to find out later that you are losing your site because yah didn't read the fine print!

I would say that finding a domain on hostinger.com can be very exciting. But if the domain is available for registration, don't forget that it's not really yours just yet.
It can be snatched away from you at any point, so be cautious and secure it as soon as you can. Ensure you understand the terms of service, because many people lose their valuable domains due to negligence or misunderstanding.

It's possible to grab a .com domain for just a buck if you use some coupon codes provided by various registar companies. I recall seeing a thred on this forum discussing deals for domain names.
