As answered by people managing BrowserStack and Klarent.
Klarent's answer:
Engineering, QA, and product teams that ship continuously - from B2B SaaS to enterprises in banking, insurance, travel, media, and e-commerce. Tests are authored in plain English with no code, so QA leads, product owners, and teams without dedicated QA can all write and verify them.
Klarent's answer:
You describe a test in plain English, and a team of AI agents writes, runs, and maintains it then self-heals it when your UI changes, so tests stop breaking. One platform covers web, native iOS/Android, and APIs. The tools comes with option for fully managed services,
Klarent's answer:
Traditional tools make you write and maintain test code, upkeep of which is where teams lose time. Klarent removes both: natural-language authoring plus automatic self-healing. Full cross-platform reach (web, mobile, API), CI/CD and Slack/Teams/Jira integrations, and enterprise-ready deployment (VPC or on-prem).
Klarent's answer:
Built by ex-Google engineers who saw the same bottleneck everywhere: manual testing is slow, and traditional automation breaks constantly. They built AI agents to handle the full testing lifecycle - writing, running, and maintaining tests so teams can ship faster without sacrificing quality
Klarent's answer:
A cloud-native, multi-agent AI platform. Specialized agents - Explorer, Planner, Coder, Verifier, Healer which are trained models. Automates across all major browsers and native iOS/Android, runs in parallel, and integrates with standard CI/CD. Enterprise-grade: encryption, RBAC, audit logs, VPC/on-prem deployment.
