You can store and manage Bambdas in the Extensions > Bambda library tab. This enables you to organize your Bambdas for easy reuse across your Burp projects. To add Bambdas to the library either create and save your own or import them from our GitHub repository.

Bambdas are listed in a table containing the following information:

Name - The name of the Bambda.
Function - The task that the Bambda is designed to perform. For example, View filter or Custom column.
Location - The tool in Burp that the Bambda is intended to be used in. For example, HTTP history or Logger.
Last modified - The time and date that the Bambda was most recently saved to the library.

You can filter the table contents as follows:

Search the table - Click Search and enter an expression.
Filter the table - Click the Filter settings bar to open the Bambda library filter window. You can filter by Function and Location.

To learn about actions you can take to quickly edit the filter settings, see Managing the filter settings.
You can customize and sort the table contents. For more information, see Customizing Burp's tables.

Importing Bambdas

You can import Bambda files that have been shared with you or downloaded from our Bambdas GitHub repository. For information on how to do this and how to keep your imported Bambdas up-to-date, see Importing Bambdas into your Bambda library.

Warning

Bambdas can run arbitrary code. For security reasons, please be cautious when using Bambdas from unverified sources.

Creating Bambdas

You can create Bambdas directly from the Bambda library. For more information, see Creating Bambdas.

Exporting Bambdas

To share Bambdas with others, select Bambdas, then click . They're exported as .bambda files.

Each file includes a unique ID, name, function, and location as metadata. Burp uses the unique ID to recognize and match Bambdas. It is important to preserve the unique ID when sharing your Bambda, as this ensures consistency and prevents conflicts if the Bambda is reimported.

For more information about how the unique ID is used when re-importing Bambdas, see Importing Bambdas - Updating your Bambdas.
You can share your Bambdas with the community by adding them to our ever-growing Bambdas GitHub repository. For more information, see Submitting Bambdas to our GitHub repository.
