About

Built by developers, demoed by sales

DemoKit runs your product demo on the real app, not a staging clone.

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 Kasava’s internal demo mode: 50-plus hand-written fixture files and 20-plus data hooks that broke a little more every release. We were tired of maintaining separate demo environments, dealing with stale data, and watching live demos break at the worst possible moments.

We’re the team at Kasava, focused on developer experience. Every API, every hook, and every line of documentation is built to get you from install to working demo fast.

DemoKit is open source at its core because we believe demo tooling 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 in narrative coherence across endpoints, not random faker output.

Open source by default

Demo tooling shouldn't be a moat. The core SDK is Apache-2.0-licensed; we charge only for hosted infra and team features.
