Introduction | Fastcart Docs

Fastcart is a lightweight, self-hosted, multi-store commerce platform built with Rust and React. It pairs a single Rust modular monolith with one SQLite database per store, an operational React admin, and a process-isolated universal SSR runtime.

What you can do

Run your own commerce stack. One binary, SQLite storage, and no mandatory Docker, Redis, PostgreSQL, or message broker.
Operate multiple stores. Every store owns an isolated database and is resolved from the request Host header on storefront routes.
Extend the platform. Commerce modules are independent crates, and capabilities are exposed through provider interfaces, plugins, workflows, and an auditable AI tool registry.

Get started

Build the workspace
```
cargo build --workspace
```

Initialize the platform

cargo run -p fastcart-cli -- init --dir .

Create an owner account

cargo run -p fastcart-cli -- user create \
  --email owner@example.com --password 'change-me-please'

Create a store

cargo run -p fastcart-cli -- store create \
  --name "Demo Store" --slug demo --domain shop.example.com \
  --owner-email owner@example.com

Serve the API
```
cargo run -p fastcart-cli -- serve
```

The API listens on http://localhost:8080 by default. In another terminal, run the admin with pnpm dev:admin and open http://localhost:5174.
