See your website mapped, tested and graded in minutes
JASUSS crawls every page across desktop, tablet and mobile, exercises real interactions and turns what it finds into a prioritised, audit-ready report.
Free to start during beta, no credit card required.
From URL to graded report in three steps
Paste a URL, optionally add a login. No SDK or code changes required to start.
Headless browsers crawl each viewport, click through flows and record evidence.
AI triage turns raw findings into prioritised defects you can export and share.
Comprehensive QA, automatically
Every scan runs the full suite across viewports, interactions and runtime health.
Inspects Desktop (1920×1080), iPhone 13 and iPad layouts to catch breakage and overflow on every screen.
Finds and exercises buttons, links, inputs and dialogs to verify the site actually responds.
Traps HTTP 4xx/5xx responses, unhandled JavaScript exceptions and console errors as they happen.
Logs in with transient, in-memory credentials to test protected routes without leaking secrets.
Root-cause analysis, P0–P4 severity, reproduction steps and a canonical letter grade.
Diffs against previous scans to flag new vs resolved defects, with PDF, Excel, JSON and Markdown export.
