> The terms for using DR4 Checker, the free bulk DR4 Domain Rating checker: fair use limits, where the ratings come from, and no warranty.

Canonical: https://dr4check.com/terms

Last updated: 2026-11-07

DR4 Checker is free to use, with no account needed. By using it, you agree to these terms.

## Fair use

Check up to 10 websites at a time, 20 a minute and 50 a day.

Don't use scripts or bots to collect ratings in bulk: Ahrefs' licence for its Domain Rating API doesn't allow it, and the limits keep the checker free for everyone.

## The ratings

Domain Ratings come from Ahrefs and are shown as Ahrefs gives them, under its Domain Rating licence (ahrefs.com/legal/domain-rating-license). DR4 Checker isn't affiliated with Ahrefs, and can't promise the ratings are complete, accurate or always available.

## No warranty

DR4 Checker is provided as is, without any warranty, and may change, pause or stop at any time. As far as the law allows, it isn't liable for decisions you make based on its ratings.

## Changes

These terms may change. The date at the top of this page shows when they last did.
