As AI accelerates how software is built, Virtuoso QA helps organisations release with confidence through governed, agentic automation for functional, regression and end-to-end testing across any browser-based application, from Dynamics 365, Salesforce and SAP to Guidewire and custom-built systems. Virtuoso QA turns requirements, designs, live applications or existing suites into executable journeys. Through Touchstone, its agentic layer, brings in 30+ specialised agents to do the work, grounded in your sources and standards. The Analyst turns documentation into source-cited test requirements, the Architect designs the journeys that prove them, and Autopilot builds each one. Your team reviews and approves each stage, so nothing enters the suite on trust. Tests run on a deterministic engine within existing CI/CD pipelines, and self-healing fixes are proposed as reviewable diffs, keeping test suites current without manual rework. Every release is backed by evidence of what was tested, what changed and who approved it. That is why organisations in financial services, insurance, healthcare and the public sector trust Virtuoso QA where releases carry consequences. 131 Ratings Visit Website StackAI StackAI is an enterprise AI automation platform to build end-to-end internal tools and processes with AI agents in a fully compliant and secure way.

Pros & Cons from Real Users Pros My team has switched to Opik from Arize about 4 months ago. We have evaluated Arize, Langfuse, Opik and Langsmith. Overall Opik was the best platform. Phoenix OSS doesn't have half the features, Langsmith is nice but super expensive and not OSS and Langfuse is brittle and has tons of performance issues. We found one bug on Opik, opened a PR on the GH repo and it was fixed and merged in less than 5 hours. Cons Personally I think they can make the UI a bit prettier.
