erebo.si Docs

Build games that work with erebo.si

Creator documentation for packaging browser games and supported platform SDK features.

AI Quickstart

Build with an AI coding agent

Use an internet-enabled coding agent such as Codex, Claude Code, Cursor, Gemini, Kimi, or another compatible agent.

SDK v4Recommended

Cloud Storage: Available
Leaderboards: Beta
Player Identity: Beta
Multiplayer: Beta
SDK SHA-256: 39b359f8…95dab

One prompt to get started

Copy this prompt into your coding agent. The agent will discover the current SDK and integration rules from the authoritative public files.

Integrate the latest official erebo.si SDK into this browser game.

First read:
https://www.3js.games/sdk/latest.json

Then read and follow:
https://www.3js.games/docs/ai-sdk.txt

Use the current recommended SDK version from the manifest.

Fetch the official SDK artifact yourself from the sdkUrl in the manifest and vendor it unchanged into this game's static output.

Do not recreate or modify the SDK.

Use only documented erebo.si APIs.

Keep standalone gameplay functional.

After implementation:
- verify the SDK SHA-256 against the manifest
- run available tests/build checks
- create an upload-ready ZIP with index.html at its root
- verify static-relative runtime paths and the vendored SDK inside the distributable
- report the ZIP path and contents
- report which erebo.si features were integrated

Do not commit or push unless explicitly requested.

Documentation principles

Statuses and contracts are written as visible semantic text for people and coding agents. Planned pages contain no speculative API signatures or executable-looking examples.
