Built for developers, loved by sales

DemoKit makes product demos effortless.

We believe demo environments should be as easy to set up as running your app in development mode. No separate databases, no complex fixtures, no maintenance burden. Just install the SDK, define your patterns, and go.

DemoKit is open source because we think every SaaS team deserves great demo tooling — not just the ones with dedicated sales engineering teams and unlimited budgets.

The team

DemoKit started as an internal tool built to solve our own demo frustrations. We were tired of maintaining separate demo environments, dealing with stale data, and watching live demos break at the worst possible moments.

We're a small, focused team obsessed with developer experience. Every API, every adapter, every line of documentation is designed to get you from install to working demo as fast as possible.

DemoKit is open source at its core because we believe great tools should be accessible to everyone.

Sales teams deserve better than broken demos. Developers shouldn't have to maintain separate demo environments. And nobody should have to apologize for production data showing up in a prospect call.

DemoKit exists to make product demos effortless. Intercept API calls, inject beautiful mock data, and let your real app shine — without the risk of real data leaking into demos.
