Fuzzilli on a Mac
Coverage-guided JavaScript engine fuzzer (reviewed local binaries) · Security Tools
Fuzzilli is Google Project Zero's open-source coverage-guided fuzzer for JavaScript engines. It generates and mutates programs in its FuzzIL intermediate language, then executes them in a dedicated engine shell built with Fuzzilli's coverage and REPRL patches. Build Fuzzilli externally from a checkout you reviewed; FrontierStack does not execute package builds. Its Security pane binds an explicit trust receipt to the canonical release CLI and engine contents before it can run bounded or continuous standalone campaigns, show live samples/coverage/corpus/crashes, retain artifacts and notify when a unique engine crash appears. Use a dedicated instrumented test shell—not Safari, Chrome, or a production engine. Distributed network modes are intentionally not exposed.
