CST VerdictBased on our analysis of available product data, here is our conclusion:
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.
Mobile security teams testing native Android libraries and system components need Android port of Radamsa because it's one of the few fuzzers that generates valid mutation sequences across ARM and x86 ABIs without requiring app recompilation. The tool's 68 GitHub stars and zero-dependency native compilation via Android NDK make it fast to integrate into CI/CD pipelines for pre-release fuzzing of C/C++ code. Skip this if you're fuzzing Kotlin/Java app logic or need guided feedback-driven fuzzing; Radamsa is mutation-based and dumb, which is exactly why it finds edge cases that smarter fuzzers miss.
