Application and use cases

Great extension, very powerful once you learn how to use it. Having tried lots of extensions there's nothing which even comes close (flexible rules and hooks, regexp support, inject javascript etc). Support is excellent, and devs are very responsive. I use Requestly for quite a few different things now, including redirecting local domains to development so I don't have to mess about managing endless dns entries.Very happy with extension especially once you use Premium.

It's the best redirect tool by far, offering much functionality and flexibility above the alternatives. If you use it a lot and could make use of a large number of rules, I'd say it's well worth buying a licence.

Mike Alcock

I love this extension! You can redirect/replace small sections of links, which is exactly what I needed. I use it to redirect things like normal Amazon links to the 'smile.amazon' version.

Zac Gorowski

Add, Delete, Override Request & Response Headers.

The ability to modify headers is a great tool for developers. It empowers them with great debugging capabilities.

Modify Headers in HTTP(s) Requests and Responses

When a web server sends an unknown MimeType to browsers, browsers automatically download the files as they are unable to understand how to parse and render the response

Prevent browser downloading images

Often companies add a header to their website so that the browser will refuse to open the page within an i-frame. But using Requestly, you can implement a work-around.

Open a website in an iframe

Can I run HTML files directly from GitHub, instead of just viewing their source?

Here's how you can use Requestly's Modify Headers feature in your daily workflow...

You can add, override and even remove headers from the URL provided. Modify headers like Authorization, Access-Control-Allow-Origin, etc.

Configure the criteria of URL on which the rules applies. Options like if the URL contains, equals or matches regex.

Request will suggest header names to ease your journey.

Add multiple conditions in a rule to match any preferred use case.
