Introduction

Jest is a platform for publishing, distributing, and monetizing interactive entertainment apps and games. Designed for instant accessibility and deep user engagement, Jest is built around three core pillars:

  • Web Runtime: Runs natively on the web, eliminating download friction and enabling instant, cross-platform access on any device.
  • Messaging Notifications: Uses native SMS and RCS channels to deliver dynamic, personalized notification messages directly to users, driving re-engagement and player retention.
  • Digital Wallet Payments: Integrates seamlessly with digital wallets for frictionless, secure in-app transactions and monetization.

To learn more about how Jest works, take a look at https://about.jest.com.

Whether you are launching a lightweight game or a full-scale entertainment app, this documentation will guide you through integrating the Jest SDK and leveraging these core capabilities.

Who is Jest for?​

Jest serves two primary audiences:

  • Users - discover, launch, and return to apps and games
  • Developers - build, publish, and operate apps and games using the Jest SDK

How the platform works​

Jest consists of three main components:

Main Platform​

The main platform lives at https://jest.com.

It functions as a web-based super-app - an application that contains other applications. Users can:

  • Sign up using their phone number
  • Discover apps and games
  • Launch apps and games instantly in their browser

Apps run inside a sandboxed environment and communicate with the platform through the Jest SDK.

Jest SDK​

The Jest SDK enables apps to access core platform capabilities, including:

  • User authentication, identity, and state management
  • Messaging notifications (SMS, RCS, and on-platform)
  • Secure in-app purchases and subscriptions

Apps and games built with Phaser, PixiJS, Cocos, Three.js, Babylon.js, Construct 3, Godot, Unity (WebGL), and other web engines can integrate the SDK.

Developer Console​

The Developer Console lives at https://jest.com/developers.

This is where developers:

  • Create and configure apps
  • Upload new builds
  • Configure products and pricing
  • Manage media assets and notifications
  • Submit apps for review
  • Monitor analytics and moderation events

Typical user journey​

  1. A user visits Jest.com and browses available apps and games.
  2. An app launches instantly in guest mode.
  3. The app prompts registration via SMS/RCS to save progress and subscribe to notifications.
  4. The app can re-engage the user later through notifications.

Unlike traditional app stores, Jest uses messaging as its primary engagement channel and web-based checkout instead of native in-app purchase systems.

In the following sections, you’ll learn how to integrate the Jest SDK, configure your app in the Developer Console, and publish your app to the platform.
