Show HN: Aha Domain Search (ahadomainsearch.com)

48 points by slig ↗ HN
Hey everyone!

Years ago, one of my favorite domain search tools, Lean Domain Search [1], was acquired by Automattic. Unfortunately, that's when the "enshitification" began, particularly when they started forcing the `.blog` TLD in search results.

After discovering the simplicity of RDAP lookups, which can be done by fetching a JSON response directly from the client (e.g., `https://rdap.verisign.com/com/v1/domain/ycombinator.com`), I decided it was finally time to build my own solution.

Here's how it works:

The first tab appends prefixes and suffixes to your chosen word and queries the Verisign API directly from your browser. No data is sent to my server.

The AI tab attempts more intelligent prefixing with the optional context.

The "Quirky" tab generates variations of the affix search through trivial merging (for instance, for the word "brain," "brain" + "node" becomes "brainode," and "hub" + "brain" becomes "hubrain").

The "Portmanteau" tab was inspired by this HN submission [2] and my personal desire [3] to see it function as a domain name generator. I'm using AI, though, as it was easier and faster to implement and get this up and running ASAP.

I'm all ears for suggestions and feedback!

Love it--feel like it helps builders fight back against domain squatters.
I have 1 suggestion, as domain order is not important, can you move available domains to the top as soon as you found them available.

thanks

ai tab Generate button is disabled for me, regardless of input
This is useful especially with the weird .blog insertion on LeanDomainSearch. But I've always wondered how LeanDomainSearch gets results so quickly? The results are almost instant for thousands of domains.
Great idea overall. The results in the AI tab are not very creative though, just variations of the same creative idea.
I found a bug: if you include a . in the domain your looking for (ie a.b), all domains will show as available, even though they aren't.
Small suggestion, in the simple tab you could put the <term>.com of the term searched as the first result. Cool project.
Love this, thanks for building it, way faster way to explore options than what I'm used to!

Could be worth adding some kind of 'only show available domains' option

(edit: realizing this may require a rework of how the underlying availability checking process works, but could be worthwhile)

I’ve tried creating similar solutions and feel LLMs still lack accurate control over (or understanding of) length, stress / accents, and phonetics for consistent name generation. For usernames for example I’ve yet to create a generator that uses LLMs that beats simple Markov chains. Maybe because results are subjective it makes rating / training a lot harder? I like the site and your approach though and great job on lookup speed! If anyone has any tricks or suggestions I'd love to hear them.
Loved it, thanks for sharing it!
Thank you! Hope you found a great name!
Some feedback:

Very cool! I will use this.

But your suggestions are not good. It's just "stick words on the front or end.

The simplest thing you can improve is include variants of the word. If I say "kayak", then kayaks and kayaking are closer to my intent than "wikikayak". Getting this right would be your secret sauce.

Obviously, non .com domains would make this much more valuable.

add a filter of "only show available domains" would be very helpful.

maybe have the option to do prefix and suffix? Probably only useful with AI or some algorithm that makes them related. MyKayakHome isn't bad.

On the quirky tab, you don't display the domain names, you show "sug+". I assume this is supposed to be added to the stem, but it's not consistent. "a+" guard gives "aguard", but "sug+" guard gives "suguard", where is the extra G?

Either way, please just show the domain name.

If I select the text for the name of a domain, you should not pop up the domain info box.

One the ai tab, I got "An error occurred in the Server Components render. The specific message is omitted in production builds to avoid leaking sensitive details. A digest property is included on this error instance which may provide additional details about the nature of the error."

On the main page, the search button is always disabled, but hitting enter works (firefox/mac). hmm not reproducible after reload.

Hey I've made a similar tool that shows only available domains and I've hooked it up to gemini to generate creative domain name, check it out!

Just gave it a spin — the direct RDAP lookup from the browser is such a nice touch. I’ve always found domain search tools frustrating when they filter or push certain TLDs, so the “no server” part is refreshing.

The “Quirky” tab is surprisingly fun — got a few name ideas I wasn’t expecting. One small suggestion: maybe add a bulk check option for multiple keywords at once? Would make brainstorming sessions even faster.
