Frequently Asked Questions

  • Is Grackle Check really completely free with no hidden costs?

    Yes. Grackle Check is completely free with no trial period, no feature gates, no accounts required, and no data collection. You install it from the Chrome Web Store and start scanning immediately. It’s our way of making accessibility testing accessible to everyone.

    When you’re ready for comprehensive manual audits, remediation strategy, and ongoing compliance support, GrackleDocs offers professional services. But the extension itself will always be free.

    • What about my accessibility data? Is this secure and private?

    Grackle Check runs entirely in your browser with zero data collection and zero data transmission. Every scan happens on your machine. Nothing leaves your computer. We use a strict Content Security Policy with no inline scripts, no eval, and no remote sources.

    You can scan password-protected internal pages, staging environments, and local development servers without any privacy concern. Your content is yours alone.

    How does Grackle Check compare to WAVE, Axe DevTools, and Lighthouse?

    All three are solid tools, and each has value. Grackle Check differentiates in a few specific ways:

    • It’s completely free —Axe DevTools charges for advanced features.
    • Grackle Check includes Focus Order and Disable CSS views for manual testing that competitors don’t offer for free.
    • A privacy-first architecture means nothing leaves your browser—we do not collect usage data.
    • Grackle Check has a five-view interface that is purpose-built for different user workflows rather than a one-size-fits-all output.

    Each tool has its strengths; the question is which one fits your team’s workflow and values.”
