Domain Availability Checker

The Domain Availability Checker is a Claude skill that instantly tells you whether a domain name is taken or available to purchase. Drop in one name or thirty. Get answers in seconds.

The Problem

Ever tried to buy a domain? It's one of the most quietly painful parts of starting anything new.

First you have to come up with the name. Already a process. Then you log into GoDaddy, or worse, fight Cloudflare's UI to find the "buy domain" button. You type your name in. Taken. You think of another. Taken. You add a "get" in front. Taken. You try .io. Taken. Twenty minutes in, you're staring at a search bar like it owes you money.

So you open a new tab, brainstorm five more names, paste them back one at a time, and play the same back-and-forth dance: thinking, typing, praying, repeating. An hour disappears. You still don't have a domain. You've just lost faith in your name.

This skill ends that loop. Hand Claude a list, or just a concept, and get every answer back in seconds.

What this Claude skill does

• Checks any domain in seconds: .com, .io, .co, .app, .dev, and more.
• Batch-checks a whole shortlist at once: paste 30 ideas, get 30 answers.
• Brainstorms domain ideas for you: give it a concept, it generates and checks variations like get{name}.com, try{name}.com, {name}hq.com.
• Double-verifies the good ones: an optional second check catches squatter-held domains that look "available."
• Keeps a history: so you're not re-checking the same names next week.

Why it's amazing!

• Dramatically reduces the time it takes to find the perfect domain
• Stop typing names into a registrar one at a time.
• Catch parked domains before you hit checkout.
• Keep every search logged so you don't redo the work next week.

Who it's for

Anyone who needs a website. But business professionals, founders, indie hackers, course creators, and brand-builders naming a new product, offer, or business. If you're still pinning down who that product is even for, the ICP Generator Skill sharpens the audience before you name the thing. Anyone who's ever lost an hour pasting names into a registrar one at a time.

How it works

Ask Claude something like:

• "Check if these are available: habitloop.com, habitloop.io, gethabitloop.com."
• "I'm naming a habit-tracking app for busy parents. Brainstorm 20 domain ideas and check which are available."

You'll get a clean list back:

• ✅ Available: habitloop.io, gethabitloop.com
• ❌ Taken: habitloop.com, habitloop.app
• ⚠️ Uncertain: tryhabitloop.com (needs verified check)

For anything you're about to actually buy, Claude will offer a verified second check to confirm the domain is truly free, not just parked by a squatter.

Pairs well with these other skills

Naming the thing is one step in launching it — these skills cover what comes before and after:

• ICP Generator Skill: Sharpen who the product is for before you name it, so the name speaks to a real audience.
• Competitor Teardown Skill: See how rivals name and position themselves before you lock in your own brand.
• SEO Website Audit Skill: Once the domain's live and the site is up, find what's keeping it off page one.

FAQ

Does it cost anything to run?

This is 100% free. No accounts or subscriptions required for this skill to work.

How accurate is it?

Very reliable on common extensions like .com, .io, .co, .app, and .dev. For edge cases (country-code domains or names parked by squatters) the optional verified check catches what the first pass misses.

Can it register the domain for me?

No. It only checks availability. You'll still buy through your favorite registrar (Namecheap, Cloudflare, Porkbun, etc.).

Does it check trademarks?

No. A domain being available doesn't mean it's legally clear to use. Search trademark databases (like USPTO in the US) before committing to a brand name.

Does it check social media handles?

No. Only domain names.

How many domains can I check at once?

Dozens at a time, no problem. The skill handles batch lists in seconds.

Will it suggest names for me?

Yes. Give it a concept ("a habit-tracking app for busy parents") and it'll brainstorm 20+ variations and check them all in one pass.

Does it remember what I've already checked?

Yes. Every check gets logged so you don't waste time re-checking the same names a week later.

Safe To Install

Please read before installing. Any skill you copy online is someone else's code running inside your Claude, and a lot of what's out there should give you pause. Most authors who give skills away don't give a second thought to quality or security. Most are vibe-coded slop pushed out untested, and some are the occasional bad actor hiding an exploit in plain sight. (Read about OpenClaws ClawHub security nightmare).
