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.
AI governance, testing, and observability for regulated enterprises
Dozens of pre-built evaluations cover quality, safety, security, and performance, with LLM-as-a-judge scorers, session-level metrics, and support for writing your own custom tests against your own data.
Import a repository and run evaluation suites automatically on every change, benchmark each iteration, and block releases when a metric regresses beyond the threshold you define.
Trace every request through multi-step agent workflows, including tool calls and retriever steps, with token counts, latency, cost per request, alerting integrations, and subpopulation analysis.
Register each AI system with an owner, purpose, data sensitivity, and risk tier, score inherent risk across multiple dimensions, and move systems through staged approval gates before they reach production.
