CST VerdictBased on our analysis of available product data, here is our conclusion:
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.
Developers and security teams shipping binaries for resource-constrained environments will get the most from UPX, which reduces executable size by 40-70% while maintaining full functionality and enabling faster deployment cycles. UPX has packed over a billion executables across embedded systems, IoT devices, and legacy infrastructure since 1996, proving its stability across ARM, x86, and MIPS architectures. Skip this if your threat model centers on preventing reverse engineering; packers obscure code but don't encrypt it, and determined adversaries will unpack your binary regardless of compression ratio.
