Write the logic. The SDK provides the rest.

Building interactive content for Twitch "by hand" is mostly plumbing: OAuth, EventSub webhooks, chat, overlay, persistence. On Kappapps, all of that is already there.

Around forty services

Chat, Twitch events, overlay, media, text-to-speech, currency, items, moderation, Phaser game engine: you connect to the SDK and only write your own logic.

A clean execution framework

Apps are versioned, declare their permissions, get per-app and per-viewer storage, and can run in the background.

Immediate distribution

Every channel that installs an app is its distribution. The announcement layer, the viewer economy and the triggers are inherited, not reimplemented.

From visual to code

Visual block builder (flowchart) or code, your choice. A local development workflow (pull, push, watch) is provided by the DEV HUB.
