About Bulk Domain Availability Checker

Bulk Domain Availability Checker gives you the evidence you need before you spend money on a name. Test hundreds of domain names for availability across every TLD. Every check returns a sortable table, so you are comparing domains on facts rather than instinct.

Because it runs in bulk, you can check an entire site, client portfolio or prospect list in one pass instead of repeating the same lookup by hand. Results come back as a sortable table you can export.

Bulk Domain Availability Checker is free to use with no account required. Signing in adds saved history, favourites and higher daily limits, and unlocks the other 311 tools on the platform.

Why teams use it

Stop paying for a single-purpose tool

Bulk Domain Availability Checker is one of 312 tools on the same account. One subscription replaces the handful of point solutions most domain teams end up stacking.

Get to the decision faster

The output is structured around what you will do next, not around what was easiest to measure. Less interpretation, fewer meetings.

Share results without a screenshot

Export to PDF or CSV, or send a link. Clients and colleagues see the same thing you do, formatted properly.

Works the same on every device

The full workspace — including tables and exports — works on a phone, a tablet and a 4K display without a separate app.
