"At Maze, we've learned great customer experiences come through intentional testing & iteration. Freeplay is building the tools companies like ours need to nail the details with AI."
Jonathan Widawski
CEO & Co-founder at Maze
"The time we’re saving right now from using Freeplay is invaluable. It’s the first time in a long time we’ve released an LLM feature a month ahead of time."
Luis Morales
VP of Engineering at Help Scout
"As soon as we integrated Freeplay, our pace of iteration and the efficiency of prompt improvements jumped—easily a 10× change. Now everyone on the team participates, and the out-of-the-box product-market fit for updating prompts, editing them, and switching models has been phenomenal."
Michael Ducker
CEO & Co-founder at Blaide
"Even for an experienced SWE, the world of evals & LLM observability can feel foreign. Freeplay made it easy to bridge the gap. Thorough docs, accessible SDKs & incredible support engineers made it easy to onboard & deploy – and ensure our complex prompts work the way they should."
