What's Freeplay?

Freeplay is the platform for software teams to ship great AI products. We give product development teams the power to test, evaluate, monitor & optimize AI in production. Our customers use Freeplay to to build better LLM features, chatbots, and agents. Already we're helping leading software companies from growing startups to Fortune 100 companies.

Why does the world need Freeplay?

Making simple requests to ChatGPT is easy. But that building production software around LLMs is much more challenging - especially for development teams without prior AI experience. They're motivated to move fast through the learning curve and focus on delivering value to customers.

Freeplay streamlines this process - making it easy for teams to develop & improve production-ready AI features quickly and confidently. Our customers love that we help them save time, avoid costly mistakes, deliver better features for their customers, and empower their entire team (engineers & non-engineers alike) to ship faster together.
