Wuuvy bytecode obfuscation

If they can't crack it, they can't quack it.

wuuvy rewrites your compiled Java so it runs the same but reads like noise. Your license checks, algorithms, and APIs stay yours.

Drops Into Your Build

Wire wuuvy into any JVM pipeline with a single command or build-plugin block. Configure once, protect every release. No source changes, no runtime agent.

CLI in any terminal

After install, ofc-jar mod my-mod.jar works in cmd, PowerShell, IntelliJ's terminal, VS Code's terminal, git-bash, and WSL. ofc-jar-inside auto-detects the surrounding project and obfuscates the freshly-built artifact.

Gradle & Maven integration

wuuvy integrate auto-detects your build system and writes a ready-to-use task. Then ./gradlew obfuscate or mvn package produces the protected jar alongside the regular one.

Composable + presets

Pick from all, mod, mod-strict, methods, light, paranoid, or pass an exact comma-separated technique list. Each pass is independent and skips itself cleanly when not applicable.

CI/CD ready

Deterministic builds (single seed → single output), ProGuard-format mapping file auto-emitted alongside the jar, clear exit codes and a errors=N counter on stdout for Jenkins / GitHub Actions / GitLab CI.

- transformation passes

Built for Commercial Software

wuuvy is designed for teams who distribute their Java applications outside their own infrastructure - where the JAR is the product, and protecting it matters.

Licensed Desktop Software

Protect license validation, activation flow, and proprietary algorithms in Java desktop products you ship to end users.

On-Prem Enterprise Apps

Harden business logic in applications deployed into customer environments, where the binary is no longer under your control.

SDKs & Redistributable Libraries

Ship JAR libraries to third-party developers while keeping internal APIs, helpers, and protocol details out of easy reach.

One License, No Subscription

Pay once. Use it on as many projects as you like, for as long as you like.
