## What this is

BrandApp Playground is the public reference implementation for `@reopt-ai/brandapp-sdk`.
It exists so a developer evaluating or integrating the SDK can see every module running
against a real backend, next to the source that produced the result.

## Who publishes it

Reopt (리옵트, legal name 주식회사 리옵트), the company behind the Reopt brand platform.

## How it is built

Next.js App Router, React Server Components, TypeScript, Tailwind CSS, and the Reopt
`opt-ui`, `opt-datagrid`, `opt-editor`, and `opt-filemanager` component packages.
Better Auth handles sessions; the Reopt adapter stores them remotely, so the app carries
no database of its own.

## Cost and access

The site is free and needs no account. The SDK is MIT-licensed and published on the public
npm registry. Bringing your own BrandApp credentials unlocks the live demos; without them
the pages still document every API.
