uk.app: £4.99 a year, not a real .uk domain
Unlike most of the tools on this site, uk.app isn't free: a standard name costs £4.99 a year and renews on its own. It isn't a national domain; it's a name shaped like yourname.uk.app, with managed DNS, dynamic DNS, and API access included in that same price.
Not everything in an AI project can be had for free, and uk.app is a clear example: it has a fixed, published price, not a free version with limits hidden somewhere. Here's exactly what you're buying for that money.

The price, no surprises
A standard name costs £4.99 a year and renews automatically; premium names have a different price, calculated separately. Availability and price are checked live on the site itself, not on a fixed list that could be outdated for the name you're looking for.
What you're actually buying for that price
It isn't a traditional .uk domain: it's a name shaped like yourname.uk.app, a different product from a national registration. In exchange, every name includes managed DNS, dynamic DNS, and REST API access, three technical pieces that other registrars usually charge for separately, or don't offer at all for a name at this price.
Why dynamic DNS matters
If your project runs on your own server, at home or on a machine you manage yourself, its IP address can change. The included dynamic DNS keeps the name pointing to the right place without you having to update records by hand every time, something that costs a separate fee on other services.
How to check before paying
Before settling on a name, the site lets you check whether it's available and at what price, with a WHOIS lookup included to see who owns it if it's already taken. That check is free; what costs money is the name once you decide to register it for a year.
What that price doesn't include
It isn't a sign of national trust or a special benefit of faster DNS propagation than any other provider. There's also no permanent free version: once the paid period ends, the name renews automatically at the same price or gets released if you decide not to continue.
Compared to leaving it for later
Short, easy-to-remember names tend to disappear fast, so checking availability today costs the same as checking it in a month, but with more options available now. Paying £4.99 a year upfront is cheaper than finding out later that the name you wanted already belongs to another project, and that fixed cost is easy to plan for in a small budget from the first month.
