@afterpack/core

The high-performance JavaScript obfuscation engine that powers AfterPack.

Built with Rust for maximum speed — 20-70x faster than alternatives.

Features

• Free & Production-Ready — Full obfuscation suite at no cost. Pro unlocks advanced tooling, not basic protection
• Irreversible Obfuscation — Non-linear transforms that can't be reversed by deobfuscators or AI
• Any Complexity Level — From minimal (--inflate=1) to extreme (--inflate=1000) protection
• Deterministic Builds — Same input = same output. CI cache friendly, HMR compatible
• Source Maps — Generate and chain source maps for production debugging
• Blazing Fast — Rust-powered, 20-70x faster than alternatives
• Dual Runtime — Native Node.js bindings + WASM for edge and browser
• Cross-Platform — macOS, Linux, Windows (x64 & arm64)
