Ship with confidence: one system of record for manual, automated, and CI tests
Manual test cases, automated test runs, and CI pipeline results consolidate into one dashboard so there are no blind spots about coverage or pass rates.
Paste a manual test case, choose a framework, and Qase generates an automation script for Playwright, Cypress, or Selenium, shrinking the manual backlog instead of growing it.
Bidirectional links connect every requirement to its test cases and results, so when something breaks you can trace exactly what was verified.
Pass rates, coverage gaps, blockers, and flaky-test history come together in shareable readiness views for confident go/no-go decisions.
Continuous AI-powered pentesting for web apps and APIs
Run unlimited automated penetration tests per target that mimic real attacker workflows, validating exploitable paths rather than just flagging CVEs.
Scan authenticated areas, business logic and access controls to surface BOLA, IDOR and privilege-escalation flaws that signature scanners miss.
Cover REST, GraphQL, SOAP and gRPC interfaces, discover shadow APIs and detect API attack patterns alongside your web application surface.
Test live production applications without disrupting them, and rely on audit-ready evidence and continuous mapping to GDPR, ISO 27001, PCI-DSS and HIPAA.
