Hey Product Hunt, I’m Caleb, the builder behind Block Cart.

Block Cart started after I spent years duct taping Notion to tools like WooCommerce and Lightspeed for real businesses. The Notion systems were fast, accurate, and valuable, but the glue always failed. Syncs broke, schemas drifted, and eventually teams fell back to manual work even though the core system was solid.

When I later built stores for my wife’s ceramic and jewelry business and for my own digital products, I ran into the same problem. Existing ecommerce platforms were bloated, fragile, or broke in ways I couldn’t control. I wanted commerce to live natively where the system already existed.

Block Cart is the result. It makes Notion the source of truth for products, orders, and customers, backed by a real storefront, hosting, SEO, and an open API. What started as working prototypes now exists so other Notion users don’t have to duct tape their systems together.

I’m launching here because Block Cart is still early, and I want the first group of makers to build this with me, not just use it.

For anyone who comes in from Product Hunt, I’m staying close in a very real way.

You’ll get full access to build and index your store, a discounted first year, and hands-on support directly from me while things are still settling. If you need help mapping your Notion database or getting your domain and SEO dialed in, you’ll have a direct line to me.

If that kind of early, close-to-the-metal setup is useful to you, I’d love to work with you.

Happy to answer questions and hear how others are handling this today.
