The toolkit

Everything you need to ship, in the browser.

From your first level to your first payout — the Developer Portal covers building, signing, publishing, and earnings without any local toolchain.

🎮

Game Builder Studio

Design levels, quizzes, and game logic in the browser-based, AI-assisted studio — then export a marketplace-ready package without leaving the portal.

🧩

JavaScript SDK

A drop-in SDK for scores, sessions, translations, and Gogo AI hooks inside your game — built for offline classrooms.

🔌

REST API

Manage games, uploads, marketplace metadata, and payouts programmatically with your developer API key.

🔏

Ed25519 signing

Every package is cryptographically signed. Classroom servers only install games from approved developers — schools trust every download.

🛒

Marketplace reach

Approved games appear in the hub catalogue, installable by any school on a supported plan across the network.

📶

Offline by design

Your game ships to classroom servers and runs on the local network with no internet — build once, and it works from Lusaka to the most rural school.

🗣️

Four local languages

Platform translation tooling helps your game speak Bemba, Nyanja, Tonga, and Lozi alongside English.

💰

Kwacha payouts

Track sales in your developer wallet and cash out from K50 to the bank or mobile money account in your profile.

How it works

From application to income in four steps.

Apply

Sign up at the Developer Portal. Applications are reviewed by the UbuntuPlay team.

Get your API key

Once approved, sign in to the portal for your API key, signing access, and wallet.

Build & sign

Create with the Game Builder Studio or your own stack, then sign your game ZIP through the portal.

Publish & earn

Set marketplace metadata and pricing, pass review, and earn 70% of every sale in your wallet.

Revenue share

You build it. You keep 70%.

For paid marketplace items, the developer receives 70% of net revenue — the platform keeps 30% to run the Hub, marketplace, and school network. Free games are welcome too.

Questions

Developers ask us.

How do I get access?

Apply at /dev/signup with your details. The UbuntuPlay team reviews every application, and once approved you can sign in to the Developer Portal with your API key ready to use.

What can I build?

Educational games and platform plugins. Games are HTML5/JavaScript packages distributed as signed ZIPs through the Marketplace; plugins extend Hub and classroom functionality. The developer docs cover both.

Do my games work offline?

Yes. Games install onto classroom servers and run entirely on the school's local network. Design for offline — no external calls — and your game works everywhere, from city labs to rural classrooms.

How do payouts work?

Sales accumulate in your developer wallet at your 70% share. Once your balance reaches K50 you can request a payout to the bank or mobile money account saved in your profile settings.

Why are packages signed?

Classroom servers only install content signed by approved developers and verified with Ed25519 keys. Schools get a guarantee that every download is safe and unmodified — and your work can't be tampered with.
