 ## Introduction
 Fetchers are classes that can do requests or fetch pages for you easily in a single-line fashion with many features and then return a [Response](#response-object) object. Starting with v0.3, all fetchers have separate classes to keep the session running, so for example, a fetcher that uses a browser will keep the browser open till you finish all your requests through it instead of opening multiple browsers. So it depends on your use case.

-# Introduction
+# Fetching dynamic websites with hard protections
 
 Here, we will discuss the `StealthyFetcher` class. This class is very similar to the [DynamicFetcher](dynamic.md#introduction) class, including the browsers, the automation, and the use of [Playwright's API](https://playwright.dev/python/docs/intro). The main difference is that this class provides advanced anti-bot protection bypass capabilities; most of them are handled automatically under the hood, and the rest is up to you to enable.
