AI-augmented quality platform for web, mobile, API and desktop testing
Generate automation scripts and test cases from natural language or tickets, get plain-language explanations, and let self-healing retry alternative locators when the UI changes so suites keep running through small front-end edits.
Cover web, API, mobile (Android and iOS) and Windows desktop applications inside one authoring environment, with record-and-playback, data-driven testing, BDD/Cucumber support and a dual-mode debugger.
Plan cycles, map requirements to cases, track coverage and flakiness, link defects in Jira, and gate releases using a shared live report that unifies manual, automated and AI-generated runs.
Run suites in parallel on real browsers, real iOS and Android devices, or your own CI runners and on-premise Runtime Engine, with lane-based parallel execution for faster coverage.
Powerful full-stack app generation from natural language, but offers more polished UI components and smoother deployment flows.
