A free account costs nothing and keeps your tests as yours. Just sign in to ensure that all tests you run are tied to your account.

The free account provides additional privacy and offers a wider breadth of use over the limited demo.

Unlike the demo, you can test a given site or single page more any number of times as long as you have sufficient credits. A free account provides 500 credits per month. A single test against a single URL requires 1 credit.

As with all accounts, your tests are private and can be accessed by you only. You can choose to share a read-only report with others.

Pages to be tested will be discovered by examining a site's XML sitemap or news feed (RSS/Atom). If no pages are discovered, the site will be crawled to discover pages to test.

Each test created under a free account will examine up to the first 10 pages discovered. A premium account is required for testing larger sites.

Tests created under your account are private. Results can be accessed only by you. You can choose to share a read-only report with others.

Results can be viewed for up to 7 days. A premium account is required to view the results of older tests.

As an account holder you have access to all types of test offered: HTML validation, CSS validation and link integrity (broken link) checking.

Free account tests cannot be carried out against HTTPS sites, are not able to use HTTP authentication and are not able to set custom cookies. A premium account is required to use these features.
