Questions
Before you sign up
Do I need to know anything technical?
No. You describe the business in plain language and answer a few questions. Every audit finding is written so a non-developer can act on it, and the auto-fixable ones are applied for you.
Can I scan a site that was not built here?
Yes, and that is the most common use. The scanner fetches any public URL, parses the real HTML and grades it. You do not need to install anything on your site.
Do I own what the AI produces?
Yes. Export a static HTML and CSS bundle whenever you like and host it anywhere. There is no proprietary runtime and no lock-in.
What happens when I hit a plan limit?
The tool tells you before you spend the generation, and nothing is lost. Metered limits reset at the start of each billing period.
Will it break my existing site?
It cannot. zrdio never writes to a site it did not publish. Scans are read-only, and generated changes always land in a new version you review first.
Can it fix my code for me?
Yes, if your site lives on GitHub. Connect the repository and zrdio applies the safe fixes directly in your HTML and opens a pull request for you to review. It never pushes to your live branch, and anything needing human judgment is listed rather than guessed.
How accurate is the accessibility check?
It computes real contrast ratios and inspects the actual accessibility tree rather than pattern-matching. Automated testing catches roughly a third to a half of WCAG issues, so it flags what it can prove and tells you what still needs a human.
