# Overview

> Learn when to use File Server, how it differs from in-place traffic modification, and how to create your first hosted mock.

Requestly Interceptor **File Server** lets you host reusable mock endpoints and static assets for testing, demos, and development workflows.

You may still see references to "File Server" in some parts of the product. This feature is called **File Server**.

## When To Use File Server

Use File Server when you want to:

* create hosted mock APIs for frontend or QA work
* serve JSON, JavaScript, CSS, images, or other test assets over a public URL
* share reusable mocks with teammates
* combine hosted mocks with [HTTP Rules](/http-interception/http-rules/overview) to redirect live requests to mock endpoints

If you only need to change traffic inside your current browser or app session, [HTTP Rules](/http-interception/http-rules/overview) may be faster. If you need a quick local response override, [API Mocking](/http-interception/api-mocking/api-mocking) may be a better fit.

## First Success Path

<Steps>
  <Step title="Create A Mock">
    Start with [Create Mock API](/http-interception/mock-server/create/create-mock-api) to define an endpoint and response.
  </Step>

  <Step title="Test The Endpoint">
    Verify the response using [Test Mock APIs](/http-interception/mock-server/test) or your preferred client.
  </Step>

  <Step title="Connect It To Your Workflow">
    Use the mock directly, or pair it with [Redirect Rule](/http-interception/http-rules/rule-types/redirect-rule) to switch traffic to your hosted mock.
  </Step>
</Steps>
