Beyond the buy button.

A store keeps moving after checkout. Build against the stock, money, and parcels behind each order.

Inventory that records the movementStock objects, reservations, and a ledger of changes.

Finance that follows the moneySupplier bills, payments, and financial accounts.

Shipping built around the parcelCarrier accounts, quotes, labels, and parcel records.

Availability depends on the store’s permissions and enabled integrations.

Good questions.

What is feeef?

feeef is a commerce platform for merchants. Its developer platform provides a REST API, OAuth apps, JavaScript and Dart SDKs, storefront templates, a CLI, webhooks, and an MCP server. Developers can work with stores, products, orders, delivery integrations, inventory, and finance.

How are feeef storefront templates built?

A feeef template is a package of text files: TSX components with JSON Schema props, page trees, settings and translations. Merchants edit it in the app (visual, code or AI) and developers with the CLI; both work on the same draft. feeef builds each published version once and the Helium runtime serves it. Templates and components can be sold on the marketplace, and buyers get the full source.

Can AI agents connect to feeef?

Yes. The hosted feeef MCP server at https://mcp.feeef.org/mcp uses Streamable HTTP and supports OAuth or a bearer token. Compatible clients can use its tools to work with stores, products, orders, delivery, inventory, and finance. API token permissions, store roles, and integration requirements still apply.

Make it yours.
