Allatori vs DashO

Allatori is a Java obfuscator that works on compiled class files to protect intellectual property and make reverse engineering more difficult. It does not require original Java source code. Its features include name, control-flow and debug-information obfuscation, string encryption, watermarking and incremental obfuscation, along with a utility for stack traces and a module intended to disrupt decompilers. It supports J2EE, J2SE, J2ME and Android targets. Build options include a command-line interface, Apache Ant, Maven, Android Studio and an Eclipse plugin. Written in Java, it can technically run wherever a Java 1.4-or-later virtual machine is supported; the maker says it has been tested on Windows, Mac OS X and UNIX. The maker reports typical application size reductions of about 10–40%, sometimes up to 60% with many third-party libraries. String encryption can add 1–2% to bytecode size, while flow obfuscation can slightly increase size and rarely reduce performance. Native methods and their containing classes are not renamed automatically. A single developer license costs $290 as a one-time purchase; the free plan is also listed.

DashO protects Android, Java, and Kotlin applications from reverse engineering, code tampering, and unauthorized debugging. It applies protection after compilation as a build step, without requiring code changes. Obfuscation options include patented Overload Induction renaming, control-flow obfuscation, and string encryption. Configurable runtime checks can detect tampering, debugging, rooted devices, emulators, and hooking frameworks, then respond according to configuration. Teams can add DashO to continuous integration through its command-line interface, Gradle plugins for Android and Java, or Ant. There is no dedicated Maven plugin; a Maven build can invoke DashO through Ant. Installers are available for Windows, macOS, and Linux/GNU, and the product processes Android applications and Java or Kotlin class files. The product page says build-time protections have little to no direct runtime impact, while configured runtime checks may add overhead. A free trial is offered, with no duration stated. Plans are quoted rather than publicly priced, and allowances vary by plan.
