Picocart
An open-source headless commerce backend.
A drop-in replacement for the parts of Shopify and WooCommerce that Autonnel needs. Shopify Admin API-compatible. Apache-2.0.
Why this exists
Autonnel currently depends on Shopify or WooCommerce as the source of truth for products and orders. Both work, but they're heavyweight for the small subset of API surface that Autonnel actually uses — and they each come with their own hosting, billing, and admin UI.
Picocart implements exactly that subset, runs on the same Cloudflare Workers + Postgres edge stack as Autonnel, and ships under the same Apache-2.0 license. Autonnel ships a built-in Picocart adapter — point it at your Picocart Worker and the funnels-to-orders path works without any integration code to write.
SaaS fees or PHP hosting.
Adapter against an external API surface you don't control.
Cloudflare free tier covers both.
Built-in adapter, Apache-2.0 end to end.
What it does
Products, variants, multi-currency pricing
Products with arbitrary variants. Per-currency price tables for cross-market funnels.
Single inventory counter per variant
Optional and explicit. No multi-location, no warehouse routing — just one number you can trust.
Orders & customers
Order create / paid / shipped / delivered / refunded. Customer records. Webhooks for downstream sync.
Shopify Admin API-compatible
The subset Autonnel actually calls. Drop-in for adapters already targeting Shopify.
What it doesn't do (yet)
- ▸No payment processing — Autonnel handles that.
- ▸No shipping rate calculator.
- ▸No tax engine.
- ▸No storefront UI — Autonnel pages render the store.
Apache-2.0. The hosted Picocart-SaaS will be free forever for individual stores.
