Check if a domain name is taken or available to register. Checks multiple extensions at once.
This tool checks whether a domain name is available for registration by querying domain registrar lookup APIs. A domain that returns no current registration data is likely available; one that returns active registration details (registrar, creation date, expiry) is already taken.
Domain names consist of a label (e.g., tulzu) and a Top-Level Domain or TLD (.com, .io, .co). The TLD significantly affects both availability and cost: .com is the most valuable and competitive, while newer TLDs like .io, .app, and .dev have more availability. When your preferred .com is taken, consider whether an alternative TLD fits your brand — but be aware that users tend to default to typing .com from memory. Domain registration costs range from $10–15/year for common TLDs to hundreds for premium domains. Renewals are ongoing — factor in annual renewal costs and enable auto-renew to avoid accidental expiry.
A domain is available if no one currently owns it and it can be registered. An available domain can be purchased immediately through a domain registrar for an annual fee. Taken domains can sometimes be acquired via domain brokers or by waiting for expiry.
You can register an available domain within minutes through any domain registrar (Namecheap, GoDaddy, Google Domains, Cloudflare). Registration is instant — the domain propagates DNS globally within 24–48 hours.
.com is the most trusted and remembered TLD for commercial sites. .io is popular for tech startups. .co is a common .com alternative. Country TLDs (.co.uk, .in, .com.au) boost local SEO. New TLDs (.app, .dev, .design) are credible but less familiar to general users.
Options: check alternative TLDs (.io, .co, .net), try slight name variations, use a domain broker to approach the owner with a purchase offer, set up a domain backorder service to catch it if it expires, or wait — many domains lapse when owners forget to renew.
