# Developers

Build on Rolebase with the GraphQL API and self-hosting.

## Overview

Rolebase is fully **open-source** and built on top of a powerful stack that makes it easy to extend, integrate, and self-host.

Whether you want to build custom integrations, automate workflows, or contribute to the codebase, this section provides everything you need to get started.

## Architecture

Rolebase is structured as an npm workspace monorepo with the following packages:

Package

Description

`packages/webapp`

React frontend (Vite, Chakra UI)

`packages/backend`

tRPC backend and serverless functions

`packages/shared`

Shared types and utilities

`website`

Documentation site (Astro)

The backend runs on [Nhost](https://nhost.io), which provides authentication, a PostgreSQL database exposed via [Hasura](https://hasura.io) (GraphQL), and file storage.

## What You Can Do

*   **Build custom integrations** using the GraphQL API to sync data with external tools.
*   **Self-host Rolebase** for full control over your data and infrastructure.
*   **Contribute** to the open-source codebase on GitHub.
