Built for developers, loved by sales

DemoKit makes product demos effortless.

Demo environments should be as easy to spin up as running your app in dev mode. No staging fork. No separate database. No team-of-one maintaining fixtures. Install the SDK, define a few patterns, demo.

We open-sourced the core because not every SaaS team has a dedicated sales engineering org. The Cloud tier exists for the stuff that’s annoying to host yourself.

Open source core

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.

Demos are developer infrastructure

We build for engineers because the people writing the SDK calls are the ones who suffer when demos break.

AI as a coherent narrator

Mock data should tell a story. We invest heavily in narrative coherence across endpoints — not random faker output.

Open source by default

Demo tooling shouldn't be a moat. The core SDK is MIT-licensed; we charge only for hosted infra and team features.
