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.

Collaborative AI agents for production software engineering
A shared representation of your code, tickets, observability signals, people and deploy history that gives every agent one source of truth to reason from.
Purpose-built agents for support triage, SRE incident response, engineering root-cause work and QA validation, delegating questions to the right owner and keeping answers in one thread.
Changes fan out into parallel scenario runs that compare actual behaviour against expectations and hold the release gate until they match.
Work is split by owner automatically, with delegated questions tracked in a single workflow so nothing stalls in an inbox.
