Glia Quest and Ghost Inspector both run automated tests against web applications, but they answer different questions. Ghost Inspector verifies that a known user flow continues to behave correctly. Glia Quest discovers whether your users can find your features in the first place. The two tools are complementary, but if you only have time to set up one, the answer depends on what you're worried about.
What each tool does
Ghost Inspector is a scripted browser testing tool. You record a sequence of actions (open this page, click this button, fill this form, expect this text), and Ghost Inspector replays the script on a schedule, alerting you if the flow breaks. It is a regression-testing tool: it catches changes that broke a path you already knew about.
Glia Quest is a discoverability testing tool. You give it a URL. It explores your application autonomously, the way a real user would, and reports which features are reachable through normal navigation and which are not. It catches a different class of problem: features that exist, work correctly, and are invisible to your users.
Pricing
Ghost Inspector is a subscription product. As of April 2026, plans are $125/month (Small), $249/month (Medium), and $499/month (Large), scaling up by test count and user seats. Glia Quest charges per audit. A full Reachability Score on a small application costs $9.99. Regression runs — repeat checks using cached scripts from a previous discovery — cost a flat $5.00 regardless of application size. Credits do not expire. There is no monthly minimum.
Who should use which
Use Ghost Inspector if you have well-defined user journeys that you need to keep working as you ship: checkout, signup, account management. The cost of breaking those flows is high, and a regression suite catches breakage before customers do.
Use Glia Quest if you suspect your users aren't finding what you've built. New features that aren't getting adoption. Support tickets asking for things that already exist. A growing product surface where the navigation hasn't kept up. Glia Quest answers the discoverability question directly, with no scripts to maintain.
How Glia Quest compares
Glia Quest uses your sitemap as ground truth to measure the gap between what your application declares and what your users can actually reach. It also produces a Quality Rating (A–F) on every scan, checking each reachable page for missing titles, exposed credentials, broken navigation components, and cross-locale rendering issues. No additional cost.
