# Addons (/ecosystem/addons)



## Overview

Each addon is a JavaScript [Bare module](https://bare.pears.com) that adds support for one or more AI tasks to QVAC ecosystem.

*If you use the SDK, you **don’t need** to use addons directly.* The SDK is the canonical way to build with QVAC: it unifies all addon capabilities under a single interface, enables QVAC to run on JS runtimes beyond Bare, and provides out-of-the-box P2P connectivity.

## Compatibility matrix

All addons support the following platforms:

| Platform | Min Version | Architecture | GPU API/Backend              | Notes                                                                       |
