Generate Random Domain Suffix

Generate fake but realistic domain suffixes for use in testing, mock data, or form validation.

Free Random Domain Suffix Generator

This tool lets you generate random domain suffixes (also known as top-level domains or TLDs) like .com, .info, .org, .biz, or .name that look real but are entirely fake in usage. Ideal for developers, testers, and data designers, it helps you simulate real-world data for form validation, demos, or mock database population with ease.

With support for generating up to 1000 random suffixes at a time, this tool provides a wide variety of common and less common TLDs to suit any testing scenario. The results are especially helpful when simulating email addresses, domain names, or web URLs for testing environments and sample datasets.

All generated suffixes are structured to reflect actual domain standards, but they’re randomly selected and not tied to real websites or entities. This makes them a safe and effective choice for realistic-looking fake data during development, UI prototyping, or performance testing.

You can download the generated TLDs as a CSV or Excel file, making it easy to incorporate them into your workflow or share with your team. Whether you’re testing input fields, simulating user data, or validating domain-related logic, this tool ensures you have the data you need quickly.

As with all our tools, this domain suffix generator is completely free to use. No sign-up or registration is required - just open the tool and start generating random domain suffixes in seconds.
