## Fetching Websites
Fetchers are basically interfaces that do requests or fetch pages for you in a single request fashion then return an `Adaptor` object for you. This feature was introduced because the only option we had before was to fetch the page as you want then pass it manually to the `Adaptor` class to create an `Adaptor` instance and start playing around with the page.

And all of them can take these initialization arguments: `auto_match`, `huge_tree`, `keep_comments`, `storage`, `storage_args`, and `debug` which are the same ones you give to the `Adaptor` class.

Also, the `Response` object returned from all fetchers is the same as `Adaptor` object except it has these added attributes: `status`, `reason`, `cookies`, `headers`, and `request_headers`. All `cookies`, `headers`, and `request_headers` are always of type `dictionary`.

### StealthyFetcher
This class is built on top of [Camoufox](https://github.com/daijro/camoufox) which by default bypasses most of the anti-bot protections. Scrapling adds extra layers of flavors and configurations to increase performance and undetectability even further.
