Domain Availability Checker

What does Domain Availability Checker do?

Domain Availability Checker is an Apify actor that checks whether domain names are available for registration across multiple top-level domains (TLDs) including .com, .io, .dev, and more. Enter base domain names and a list of TLDs, and the actor will systematically check each combination and report availability status. It is an essential tool for entrepreneurs, brand managers, and developers searching for the perfect domain name.

Why use Domain Availability Checker?

• Bulk checking -- Test hundreds of domain name and TLD combinations in a single automated run.
• Multi-TLD support -- Check availability across .com, .io, .dev, .net, .org, and any other TLD simultaneously.
• Structured results -- Get clean JSON output with domain name, TLD, and availability status for easy filtering.
• API access -- Integrate domain availability data into your naming tools and workflows via the Apify API.
• Reliable checking -- Uses Apify Proxy for consistent access to domain lookup services.

How to use Domain Availability Checker

1. Visit the Apify Store and find Domain Availability Checker.
2. Click Try for free to open the actor in Apify Console.
3. Enter the base domain names to check (without TLD) in the Domain Names field.
4. Specify which TLDs to check in the TLDs field (e.g., .com, .io, .dev).
5. Click Start and review results in the Dataset tab.

Input configuration

Field	Type	Description	Default
names	Array of strings	Base domain names to check (without TLD)	["testdomaincheck123"]
tlds	Array of strings	Top-level domains to check	[".com", ".io", ".dev"]

Output data

Each record represents one domain name and TLD combination with its availability status and a timestamp of when the check was performed.

{
  "domain": "testdomaincheck123.com",
  "name": "testdomaincheck123",
  "tld": ".com",
  "isAvailable": true,
  "checkedAt": "2025-12-01T14:30:00.000Z"
}

Cost of usage

Domain Availability Checker uses pay-per-event (PPE) pricing at the Mid tier:

Tier	Cost per 1,000 events	Free events per month
Mid	$0.75	~6,600

Each domain-TLD combination checked counts as approximately 1 event. Checking 10 base names across 5 TLDs (50 combinations) would cost about $0.04. The free tier handles roughly 6,600 checks per month, which is plenty for most domain research sessions.

Tips and advanced usage

• Brainstorm at scale -- Enter a large list of creative name variations and let the actor check them all against your preferred TLDs.
• Schedule availability monitoring -- Use scheduled runs to periodically check if a desired domain becomes available after expiration.
• Prioritize TLDs -- Check .com first since it remains the most recognizable, then fall back to .io or .dev for developer-focused brands.
• Filter available domains -- After the run, filter the dataset for isAvailable: true to see only registrable domains.
• Combine with brand research -- Use alongside trademark databases to ensure your desired domain name does not conflict with existing brands.
