CST Verdict

Based on our analysis of available product data, here is our conclusion:

Fuzzilli

JavaScript security teams and browser vendors hunting for engine-level vulnerabilities should use Fuzzilli; it's purpose-built to find bugs that static analysis and functional testing miss. The tool has been battle-tested by Google and Mozilla, with 2,080 GitHub stars reflecting real adoption in production fuzzing pipelines. Skip this if you're looking for a general-purpose application fuzzer or need to test non-engine JavaScript code; Fuzzilli's value collapses outside the narrow domain of JavaScript engine development.
