Writing your first Burp Suite extension
Summary: PortSwigger published a walkthrough for writing a first Burp Suite extension, which can be built in Java or Python and loaded through Burp's Extender tool. The post covers creating an empty extension in either language, exporting the Burp Extender interface files, and loading the resulting JAR or .py file into Burp v1.5.01 or later.
What you should know: The post notes that loading several Python extensions, or reloading one repeatedly, can exhaust Jython's PermGen memory and throw errors unless Burp is started with a larger MaxPermSize - a limit a team extending its tooling in Python will hit.
