# Choose a package

> Four packages ship under the @waniwani scope. Pick the one that matches what you are building.

Each package has its own section in the switcher at the top of the sidebar. Start with the one that matches the job, and add the others when you need them.

> [card] [@waniwani/sdk](https://docs.waniwani.ai/sdk/introduction.md)
>
> A library you add to your own MCP server. Flows, event tracking, knowledge base.

> [card] [@waniwani/kit](https://docs.waniwani.ai/kit/introduction.md)
>
> A framework that turns a folder of tools, widgets and flows into a deployable MCP app.

> [card] [@waniwani/chat](https://docs.waniwani.ai/chat/overview.md)
>
> The chat widget for your website, as a script tag or as React components.

> [card] [@waniwani/cli](https://docs.waniwani.ai/sdk/cli/overview.md)
>
> Log in, link a repo to an agent and try a local server in the hosted playground.

## Which one do I need?

| Package | What it is | Use it when |
| - | - | - |
| **`@waniwani/sdk`** | A **library**. You keep the `McpServer`, the transport and the build. | You already run an MCP server, or you want one you control line by line, and you want funnels, tracking or a knowledge base inside it. |
| **`@waniwani/kit`** | A **framework**. It owns the server, the transport, the bundler and the deploy files. It uses the SDK underneath. | You want to ship an MCP app and keep no plumbing in your repo. |
| **`@waniwani/chat`** | The **chat widget**. `embed.js` for any site, `WaniwaniChat` and `ChatEmbed` for React. | You want your agent on your own website. |
| **`@waniwani/cli`** | The **platform CLI**. `login`, `switch`, `connect`, `dev`. | You want a local repo wired to app.waniwani.ai. |

The kit and the SDK are the pair people mix up. The kit is the SDK plus everything around it, so if you are unsure and starting from zero, start with the [kit](https://docs.waniwani.ai/kit/quickstart.md).
