Introduction

Hydra is a hosted headless commerce API. It handles products, inventory, orders, checkout, payments, shipping, and webhooks. You build the frontend with whatever framework you want.

Why Hydra?

• API-first. Every feature is accessible through a clean REST API with consistent conventions
• Multi-tenant. Each project is isolated with its own data, API keys, and configuration
• Developer-friendly. Consistent conventions, typed SDK, and comprehensive documentation

We play nice with…

Next.js, Astro, Nuxt, SvelteKit, Remix, Gatsby, Angular, plain HTML, mobile apps, or anything that can make an HTTP request. Hydra is a REST API. If your framework can fetch, it works.

How it works

1. Create a project. Sign up, name your project, and get your API keys
2. Add your products. Use the admin panel or API to manage products, collections, and inventory
3. Build your frontend. Use the API to display products, handle cart, and process checkout
4. Go live. Connect your payment provider and start selling

Quick example

Fetch products from your project in any framework:

const res = await fetch('https://api.hydrajs.dev/v1/products?limit=20', {
	headers: {
		Authorization: 'Bearer sk_your_api_key',
	},
});

const { data: products } = await res.json();

Everything your merchant needs, nothing they don’t
