## Overview

[Hookah](https://github.com/xstelea/hookah) is an open-source [Radix](/contents/tech/core-protocols/radix-engine) event-monitoring and webhook-delivery platform by [Alex Stelea](https://github.com/xstelea) (xStelea), a prolific author of Radix developer tooling. Developers authenticate with [Radix ROLA](/developers/frontend/03-rola-authentication), register on-ledger event triggers, and receive real-time webhook deliveries when matching events appear in the Radix transaction stream. The MIT-licensed repository remains active; the previously hosted service (hookah.ing) is now offline.

## Architecture

Hookah is a TypeScript monorepo (Turborepo + pnpm) with several components: a **Streamer** worker that follows Radix transactions and dispatches matching webhook deliveries; a **Dashboard** (Next.js) serving the web app, authentication, and tRPC/JSON-RPC endpoints; a Docusaurus documentation site; and a webhook test-server helper. It builds on the [Radix Gateway API](/contents/tech/core-protocols/radix-gateway-api) and the `radix-web3.js` library, with PostgreSQL, Redis, and Drizzle ORM for storage.
