The BApp Store contains community-created extensions that you can install directly from Extensions > BApp Store in Burp with a single click.

We review all extensions submitted to the BApp Store, but as they are written by third parties, we can't guarantee their quality or security. We recommend that you review the code yourself before installing. To view the source code for an extension, visit our GitHub page.
