Civitai AppsBuild inside Civitai.

Ship a small web app that renders inside civitai.com — authenticated, Buzz-aware, and hosted for you. Currently in closed beta.

Introduction

Quickstart

Concepts

Reference

Ship a ZIP, not infrastructure

You build a static SPA (Vite + React). Submit a ZIP; a moderator reviews it; the platform builds, deploys, and serves it at your own subdomain. No Docker, DNS, or OAuth-client setup.

A trust frame around your iframe

Your app runs in a sandboxed iframe. The host hands it a short-lived, scoped token plus the page context over postMessage, and mediates anything privileged.

Generation and Buzz, host-mediated

Estimate, submit, and poll orchestrator workflows; read the viewer and their Buzz balance — the host brokers every privileged call on the platform side.

React SDK + component pack

@civitai/blocks-react ships useBlockContext, useBuzzWorkflow, useAppStorage, and a themed component pack; @civitai/app-sdk carries the framework-agnostic contract.
