AI teams ship faster with Freeplay
"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
"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
"Freeplay transformed what used to feel like black-box ‘vibe-prompting’ into a disciplined, testable workflow for our AI team. Today we ship and iterate on AI features with real confidence about how any change will impact hundreds of thousands of customers."
Ian Chan
VP of Engineering at Postscript
"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."
