The resulting graph allows for the analysis of the proximate and upstream causes of every modification in the document. Every relevant event in the document (a node being created, a network request being triggered, a script being executed, etc.) is recorded in the graph, noting both the relevant event, and the event's cause. PageGraph's name comes from the graph-based representation of the document's execution it builds in memory. this choice is made to slightly optimize the performance of the Beta and Stable builds that most Brave users use. Note that recording builtin JS APIs requires nightly Brave builds. Th easiest way to run PageGraph is to use pagegraph-crawl tools and scripts, which automate enabling PageGraph in Brave, launching Brave, and recording the resulting graph files. PageGraph is included in all builds of Brave starting with version 1.46, though enabling it requires passing some command line arguments.
PageGraph is a research project developed by Brave to instrument Brave browser, blink and v8, to allow for complete attribution of document modifications, network requests, script execution, and privacy-relevant Web API accesses.
