LeetCommerce

Multi-tenant e-commerce on Cloudflare Workers, built for Bangladesh: cash on delivery with SMS confirmation, local payment and courier integrations, a Bangla-first storefront, and a store that AI agents can read and buy from.

The demo uses simulated payments and couriers, shows SMS and email on screen, and resets every night.

What to try

• Buy with cash on delivery

  Add a Panjabi to the cart, apply EID10, check out, then confirm the order with the SMS code shown on the order page.

• Run the shop

  In the admin: confirm orders, book a courier, edit variants and stock, import products from CSV, create discount codes.

• Ask the AI assistant

  It reads products, stock and orders, and proposes changes. Nothing changes until someone approves it in the review queue.

• Connect an agent

  Point an MCP client at https://demo.leetlab.dev/mcp to search, fill a cart and place an order as a shopping agent.

How it is built

• One Durable Object per store

  Each tenant's catalogue, carts, orders and audit log live in its own SQLite Durable Object (Drizzle, synchronous transactions). Zero oversell under concurrent checkout, tested.

• Edge routing by host

  A gateway Worker routes each store's hostname to the storefront (Astro), admin (React) or API (Hono) Worker through service bindings.

• One tool registry

  Every admin operation is defined once with its schema and permission; the Admin API routes and the agent's tools are generated from it.

• Outbox to queue

  State changes write an outbox in the same transaction; an alarm flushes it to Cloudflare Queues, where a jobs Worker sends bilingual emails.

• Agent-readable stores

  JSON-LD on product pages, llms.txt, Google and OpenAI product feeds, and a stateless MCP server.

• Safety built in

  Money as integers, tenant from the verified host, encrypted provider credentials, problem+json errors, rate limits and an AI spend cap.
