In the new landscape of AI, the single most valuable currency is trust. Freeplay has become the bedrock of our ability to build that trust, delivering a seismic shift in our capabilities—taking our prompt accuracy from a volatile 50% to a rock-solid 99%. What's truly stunning is the velocity at which this transformation happened. The platform is incredibly intuitive; the ease of implementation was remarkable, and we were fully integrated and operational in less than a week. This frictionless integration meant we realized a monumental ROI in days, not the months we'd expect from enterprise-grade tools. Freeplay has since become the daily heartbeat of our AI operations. Its brilliantly designed experimentation platform allows us to quickly deploy and validate new prompts without touching a single line of production code. This is a total game-changer, removing a massive engineering bottleneck and enabling a level of agility that was previously unimaginable. Running AI-judged and human-judged evaluations side-by-side across models has given our team the empirical data needed to make high-stakes decisions with absolute confidence. Beyond the phenomenal product, the team is in a class of its own. They've been incredibly responsive, acting less like a vendor and more like a dedicated extension of our own team. For any leader building the future, Freeplay isn't just a tool—it's your strategic advantage.

Freeplay has become one of the most important tools we use in our work. This platform allows us to effectively streamline and simplify our data logging, labeling, and auto graded evaluation processes. In addition, the Freeplay team has been exceptional at supporting our team, whether it was for learning about the different features, debugging issues we had with data imports, improving auto evals, and more. I really appreciate the efforts and patience the team continuously put into helping us and our unique requirements. Would definitely recommend this product to others.

Non-technical user accessibility: The platform enables domain experts and prompt engineers to run evaluations through the UI while still providing SDK access for engineers. This dual approach allowed our entire team to collaborate effectively without creating bottlenecks. Production-ready testing capabilities: Freeplay handled our complex requirements, including custom evaluations for brand voice, emoji usage, and message structure across hundreds of merchants. The platform supported our critical API migration from OpenAI Assistants to the Completions API right before a major launch. Flexible evaluation types: The system supports LLM-as-a-judge, code-based evaluations, and human labeling, providing our team with multiple validation approaches tailored to our specific needs.
