I Built a Free Subdomain Platform for Developers — Here's How

Vipin R on March 17, 2026

Every developer has hit this moment — you have a side project, an API, or just something you want to test publicly, but you don't want to buy a dom...

I gave it a quick try working as expected. however I couldn't find any API guide. BTW, your RSS feed is not working. the temp mail is an awesome idea looking forward to test. API is crucial for updating our main A records with new IPs and I presume there are so many other use-cases. Thanks again for offering this for free.

Thank you so much for trying it out and for the detailed feedback 🙌

You’re absolutely right — API access is crucial, especially for use cases like dynamically updating A records. We’re actively working on a proper API guide and will be rolling it out soon.

Also, good catch on the RSS feed issue — we’ve fixed that in our latest release.

We’ve just launched Nxtdev V3, and we now officially support DDNS (Dynamic DNS) 🎉 This makes it much easier to keep your domains updated automatically with changing IPs and host services from your home server.

You can check it out here:
Nxtdev DynamicDns

Really appreciate your support, and feel free to share it with others who might find it useful. More updates coming soon

I really like this idea but why not .dev? Can I sponsor you a dev extension.

Honestly, .dev would be awesome! 😄 Thank you so much for the generous offer.

As a starting point we went with .xyz to keep things flexible, but .dev and more extensions are definitely on the roadmap as we grow and get more users.

Would love your support — share it with your friends and fellow devs too, every bit helps! 🙏

.dev is better I agree. I assume it might be cost of renewal the root domain.

I guess but if you charge users just 50c, a few users could cover the cost of the renewal?

That's actually a fair point! 😄 Even a small contribution from users could easily cover the renewal cost.

But for now we want to keep it completely free — no barriers for any developer regardless of where they're from. Maybe in the future a voluntary "support us" option could work without forcing anyone to pay.

Thanks for the idea though, really appreciated! 🤍
