Setting up your extension development environment using the starter project - Port Swigger
Summary: PortSwigger's starter project for Burp extensions using the Montoya API lets developers download a ready-to-use template from Extensions > APIs, open the ExtensionTemplateProject folder in an IDE, and begin coding without manual environment setup. The project requires Java 21 or lower, is renamed via settings.gradle.kts, and includes a CLAUDE.md file so an LLM such as Claude Code can draft extension code, which PortSwigger says must be reviewed and tested.
Bottom line: The template ships a CLAUDE.md file that feeds model context directly into extension development, and PortSwigger's own guidance warns the generated code may not be correct or secure - so LLM-drafted extensions land in Burp with your review as the only control.
