Does Replo support Hydrogen?

Last updated: February 24, 2026

TL;DR

Replo doesn't integrate directly into Hydrogen codebases. Instead, Replo lets you build high-converting landing pages and campaigns on a standalone domain (like shop.yourbrand.com) that connects to your Shopify backend—the same backend your Hydrogen store uses.

How It Works

If you're running a headless Shopify setup with Hydrogen, you can use Replo alongside it:

  • Your Hydrogen site lives on your main domain (e.g., yourbrand.com)

  • Your Replo pages live on a separate subdomain (e.g., shop.yourbrand.com)

  • Both pull from the same Shopify backend—products, inventory, and checkout are synced

  • Replo Sites publishes to a subdomain (e.g., shop.yourbrand.com)

  • Replo's Shopify Theme Page Builder can also publish to a different subdomain (e.g., pages.yourbrand.com)

The key constraint: each subdomain can only be occupied by one technology. So if your root domain runs Hydrogen, you'll need to use separate subdomains for any Replo-built pages.

This gives your marketing team a space to build campaigns, landing pages, and sales funnels without touching your Hydrogen codebase or needing developer resources.

Why This Approach?

Hydrogen codebases are complex and unique to each brand. Direct integration would require understanding your specific architecture, component library, and deployment pipeline. Instead, Replo lets you build complete experiences on a standalone domain while maintaining full integration with your Shopify backend.

Which Replo Product Should I Use?

Both of our editors will work with headless stores:

  • Replo Sites: This is our standalone AI powered site builder that publishes to its own domain/subdomain—similar in concept to Hydrogen itself. Great for full marketing sites and landing pages.

  • Replo's Shopify Theme Page Builder: Publishes pages to a Shopify theme. For headless stores, this means setting up a theme-based subdomain specifically for your Replo pages.

You can even use both products simultaneously—just make sure each is configured with a different subdomain.

What You Get

  • Full product catalog sync from Shopify

  • Cart operations through Shopify's headless cart

  • Checkout via your existing Shopify Checkout

  • Cross-domain pixel tracking (Meta, TikTok, Google, etc.)

  • No developer resources needed for campaigns
