Glad you're here! **bknd** is a lightweight, infrastructure agnostic and feature-rich backend that runs in any JavaScript environment.

- Instant backend with full REST API
- Built on Web Standards for maximum compatibility
- Multiple ready-made [integrations](/integration/introduction) (standalone, runtime, framework)
- Official [API SDK](/usage/sdk) and [React SDK](/usage/react) with type-safety
- [React elements](/usage/elements) for auto-configured authentication and media components
- Built-in [MCP server](/usage/mcp/overview) for controlling your backend
- Multiple run [modes](/usage/introduction#modes) (ui-only, code-only, hybrid)

## Preview

Here is a preview of **bknd** in StackBlitz:

<Card className="p-0 pb-1">
  <StackBlitz path="github/bknd-io/bknd-demo" initialPath="/" />
  <Accordions className="m-1">
    <Accordion title="What's going on?">
      The example shown is starting a [node server](/integration/node) using an [in-memory database](/usage/database#sqlite-in-memory). To ensure there are a few entities defined, it is using an [initial structure](/usage/database#initial-structure) using the prototype methods. Furthermore it uses the [seed option](/usage/database#seeding-the-database) to seed some data in the structure created.

      To ensure there are users defined on first boot, it hooks into the `App.Events.AppFirstBoot` event to create them (documentation pending).

## Quickstart

Enter the following command to spin up an instance:

<Tabs groupId='package-manager' persist items={[ 'npm','bun' ]}>

```bash tab="npm"
npx bknd run
```

```bash tab="bun"
bunx bknd run
```

</Tabs>
