Bambdas are small sections of Java-based code 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 either create your own Bambdas or import existing ones that have been shared with you or downloaded from our Bambdas GitHub repository. Once added to your Bambda library, you can easily reuse Bambdas across Burp and in different projects.
