Requestly supports rq_rand(X) as a predefined function which can be used to add a random number with X number of digits when you do a URL rewrite.

For example - Suppose you want to add a random number to all Javascript URLs matching www.example.com, you can set up a Modify QueryParams Rule like this -

Note - If you add cache buster to all URLs, it might make your browsing a bit slow so you can add additional filters if you intend to add cache buster query param to only particular resources

Here's an example of setting up filters for matching a Rule

This can be really helpful in web development to avoid caching especially when using webpack bundles.
