Web Socket History Exporter
Summary: PortSwigger's BApp Store lists a third-party Burp extension called WebSocket History Exporter, version 1.0.0, authored by SpinHerder and last updated 23 September 2025. The extension adds a dedicated interface for selecting, configuring, and saving WebSocket message history to structured file formats, integrating with Burp's WebSocket History view for documenting and analyzing real-time web application communications.
Bottom line: WebSocket traffic is where real-time application data moves, and this tool exists to pull that message history out of Burp into structured files - which means the same records can leave your testing environment as artifacts. PortSwigger states plainly that these extensions are written by third-party users and come with no warranty of quality or usefulness, so the code you install into your scanner is someone else's.
