About Functionize

Functionize is a commercial AI-driven test automation platform for web and enterprise applications. Its current product, Studio, is presented as an independent testing agent for full web UI workflows: users describe what to test, and Studio builds the tests, runs them against the live application and keeps them working as the app changes.

The vendor frames Studio as a quality layer for software increasingly written by coding agents, using reasoning where it helps and deterministic behavior where answers must be exact. Pages are organized by audience, including testers, developers and leaders, and by industry, including healthcare, insurance, financial services and SaaS. A free trial is offered with bonus credits on all plans, and a pricing page and an enterprise offering are listed.
