Bambdas are scripts that you can run directly from Burp Suite's interface. They enable you to quickly personalize various tasks, such as creating custom match-and-replace rules, table columns, and filters.

You can create your own scripts and save them to your Bambda library for easy reuse. You can also import existing scripts shared by others or downloaded from our Bambdas GitHub repository. Once a script is in your Bambda library, you can easily reuse it across Burp and in different projects.
