# Developer Reference

Interact with your Roboflow account with our API, SDK, or CLI.

{% hint style="warning" icon="key" %}
Find your [API Key here](https://app.roboflow.com/settings/api).
{% endhint %}

With these developer tools, you can upload and download data, manage your projects, run inference, and more.

## Inference

Packages from [Inference](/reference/inference/choosing-the-right-tool.md), the open source deployment framework, for running models and Workflows yourself. Not sure which one you need? See [Choosing the Right Tool](/reference/inference/choosing-the-right-tool.md).
