Quick answer: You can check domain name availability for free using a consolidated search tool like Namecheckly. It queries ICANN registries and over 20 social platforms simultaneously in under 5 seconds. Based on our analysis of 1.2M+ searches, securing a .com alongside matching Instagram and TikTok handles is critical, as 80% of top startups use a .com domain. You only pay when you register (typically $8-$15/yr), and no account is required to search.
Check domain and social handle availability instantly in one free search — no signup, no account required. Enter your name below to see which .com, .io, .ai, .co extensions and social handles (Instagram, TikTok, X, YouTube) are actually available before you commit.
Found it available? Lock it in before someone else does — register it at Namecheap from $6.75/year with free WHOIS privacy included.
Is "[yourname].com" available?
To check if a specific domain is available, type the name into the search box above. You'll get a real-time yes/no across every major TLD in under 5 seconds — plus whether the matching @handle is free on Instagram, TikTok, X, YouTube and more. No account required, unlimited searches.
Why should I check domain availability before doing anything else?
Most founders check domain availability as an afterthought — after printing business cards, setting up a logo, or announcing the name publicly. That's backwards. Your domain is your primary online address, and availability needs to be confirmed at the very start of the naming process, for three reasons:
1. Names get squatted fast. If you mention a name publicly before registering it, domain squatters can see the activity and register it before you do. It happens more than you'd think.
2. Your domain and social handles need to match. If yourbrand.com is available but @yourbrand on Instagram is taken by an active account, you have a brand consistency problem. A partial win is still a problem.
3. It costs nothing to check. There's no reason to fall in love with a name before you've confirmed you can actually own it across your key platforms.
How do I check if a domain is available?
Step 1 — Search Your Name on Namecheckly
Go to namecheckly.com and type your brand name into the search bar. You'll instantly see:
- Whether your
.com,.io,.co,.ai, and other TLDs are available - Whether your handle is free on Instagram, TikTok, X, YouTube, Facebook, LinkedIn, Pinterest, and more
This single search replaces going to a registrar, then manually checking each social platform. Do it first, before anything else.
Step 2 — Prioritize .com First
When reviewing results, focus on .com before anything else. It's still the default expectation for most users worldwide, especially in B2C and general business. If .com shows as available, that's your target — move to Step 3.
If .com is taken, note whether it's actively used (check the site) or parked/expired. A parked domain is a possible purchase. An active site means you need a different approach (covered in the "What to Do If It's Taken" section below).
Step 3 — Check Your Social Handles
Domain availability alone isn't enough. In the same Namecheckly results, review which social platforms show your name as available. Ideally, you want the handle free on the 3–4 platforms most relevant to your business. For most brands: Instagram, TikTok, X (Twitter), and YouTube.
If a major handle is taken by an active account, that's a signal to reconsider the name — even if the domain is free.
Step 4 — Register the Domain Immediately
Don't wait. Once you've confirmed availability on Namecheckly, click through to register your domain with Namecheap. Domains are typically $8–$15/year for a .com, and Namecheap consistently has the most transparent pricing — no surprise renewal hikes that some registrars are known for.
Register first, then continue planning. A domain you haven't registered doesn't belong to you.
Step 5 — Secure Your Social Handles
After registering the domain, immediately create accounts on your priority social platforms — even if you're not planning to use them right away. Claiming a handle costs nothing and protects your brand from being taken by someone else or a squatter as your name becomes known.

What are the best free domain availability checker tools?
There are several solid options, each with a slightly different focus:
Namecheckly — Best for checking domain + social media availability simultaneously. One search, instant results across all major platforms. Free, no account required. Start here.
Namecheap — Best registrar for checking and immediately registering. Clean interface, transparent pricing, includes free WhoisGuard privacy protection. Use this to actually register once Namecheckly confirms availability.
GoDaddy — Household name, widely used. Watch out for upsells and higher renewal prices. Better for checking than for registering at competitive rates.
ICANN WHOIS — The official, authoritative lookup. Useful for checking registration details on taken domains (expiry dates, registrant info). Not ideal as a discovery tool.
For most founders, the workflow is simple: Namecheckly to discover → Namecheap to register.
Where can I check domain and social availability together?
Most tools answer only half the question. A registrar like GoDaddy or Namecheap tells you whether yourbrand.com is free, but says nothing about whether @yourbrand is still open on Instagram, TikTok, X, or LinkedIn. So founders end up running the domain check on one site, then opening five social platforms in separate tabs to check each handle by hand.
The reason this matters: a domain win with a taken social handle is a half-win. If you register yourbrand.com and only later discover an active account already owns @yourbrand on Instagram, you're stuck either fragmenting your brand (@yourbrand_official) or rethinking the name after you've already paid for the domain.
Namecheckly's name checker is built specifically for this combined check. One search returns:
- Domain availability across
.com,.io,.ai,.co,.netand more - Social handle availability on Instagram, TikTok, X (Twitter), YouTube, Facebook, LinkedIn, Pinterest, and others
— side by side, in under five seconds, with no signup. That's the fastest way to confirm a name is genuinely yours to own everywhere, not just on the domain side. For a platform-by-platform walkthrough of the social side, see the social media name checker guide.

Should I choose .com, .io, or .ai?
The TLD (top-level domain — the part after the dot) matters more than most people think. Here's how to decide:
.com — The Default
Still the strongest TLD for credibility, memorability, and type-in traffic. Users default to typing .com when remembering a URL. If you can get the .com, get it. For anything targeting a general consumer audience, .com is the right call.
.io — For Tech & Dev Tools
.io has become widely accepted in the tech startup and SaaS world. If your audience is developers or technical users, .io is a credible choice. It still looks unfamiliar to general consumers.
.ai — For AI-First Products
.ai has surged in demand since 2023. It signals an AI-native product and is widely understood in the startup community. It costs more (typically $60–$80/year) and may confuse non-technical users if your product isn't actually AI-focused.
.co — Shorthand for Company
A reasonable alternative to .com with decent brand recognition, especially in startup circles. Weaker in established markets where users might accidentally navigate to the .com version instead.
.org, .net, and Others
Reserve .org for nonprofits and community projects where it genuinely fits. .net has no clear brand signal. Other niche TLDs (.shop, .app, .design) can work for very specific use cases but should be your last resort.
Rule of thumb: If .com is taken, try a modified .com (with a word like "get", "use", "try", "hq") before defaulting to an alternative TLD. getyourbrand.com is usually stronger than yourbrand.io.

What should I do if my domain is already taken?
A taken .com isn't the end of the road. Here are your real options, in order of what to try first:
Option 1 — Check If the Domain Is Parked or Expired
Look up the domain in WHOIS or a registrar search. If it's parked (no real website, just a placeholder page) or recently expired, the owner may be open to selling. You can also wait for it to fully expire and backorder it through Namecheap's backorder service.
Option 2 — Try a Modified .com
Add a short prefix or suffix to free up a great .com:
get[name].com— getnotion.com, getbase.comuse[name].com— usepost.com[name]hq.com— slackhq.comtry[name].com— common in SaaS
Run the modified version through Namecheckly to confirm the domain and social handles are available before committing.
Option 3 — Buy It on the Secondary Market
If the domain is in active use or parked at a premium, you may be able to buy it. Marketplaces like Sedo, Afternic, and Namecheap's own marketplace list domains for sale. Prices range from $500 to well into six figures depending on the name. This is worth it if the name is truly important to your brand — but don't overpay early before you've validated the business.
Option 4 — Pivot the Name
If the .com is taken by an active competitor or a high-priced premium domain, the cleanest solution is often a name variation. Use a tool like Namecheckly to test variations quickly until you find one where both the domain and social handles are fully available.

What mistakes should I avoid when checking availability?
Only checking the domain and skipping social handles. Domain + social consistency is what makes a brand cohesive. Check both at the same time with Namecheckly.
Waiting before registering. If a domain is available today, register it today. Don't sleep on it — domains get registered every second.
Defaulting to a weak TLD because .com is taken. Try a modified .com first. getyourbrand.com is almost always stronger than yourbrand.xyz.
Falling in love with a name before checking. Check first. Pick the name based on what's actually claimable, not just what sounds good in theory.
Checking domain name availability is a 10-second task that saves weeks of potential brand confusion down the road. Do it at the start of the naming process, check your social handles at the same time, and register the moment you find a match you love.
Start with a free search on Namecheckly to see your domain and social handle availability in one shot — then head to Namecheap to lock it in before someone else does.
