ProGuardCORE is very similar to ASM; they have a similar feature set and a similar visitor-based API. ProGuardCORE came about because ProGuard itself never used ASM when the project was started 20 years ago. We split out ProGuardCORE from ProGuard 2 years ago, to provide as a library the core underlying bytecode manipulation & analysis tools that ProGuard and the Android security solution DexGuard both use. Much of our recent focus in ProGuardCORE has been on the code analysis components: we've recently added to ProGuardCORE some of the analyses that power our AppSweep mobile security scanning service (https://appsweep.guardsquare.com/ https://appsweep.guardsquare.com/). For example, taint analysis https://guardsquare.github.io/proguard-core/taintcpa.html https://guardsquare.github.io/proguard-core/taintcpa.html
