About

JavaScript Obfuscator protects browser and Node.js code against reverse engineering and tampering. Use the free online tool, the Windows desktop app, or the javascriptobfuscator-com npm package in builds and CI, with plugins for webpack, Vite, Rollup, esbuild, Next.js and Metro. Protection includes identifier renaming, string encoding and encryption, control-flow flattening, dead-code insertion, member protection, domain and date locking, self-defending output, debugger friction, and VM bytecode protection for marked functions. Teams that cannot send source to a third party can protect locally in the desktop app. Releases can be verified with Ed25519-signed attestations and opt-in reproducible builds. Migrating from javascript-obfuscator or JS-Confuser takes one command: the CLI converts your existing configuration. Free tier available; paid plans from $29/month.

About

jsObf is a powerful, web-based JavaScript encryption and obfuscation tool that enables users to transform readable JavaScript code into obfuscated, secure versions via direct input or file uploads (up to 5 MB). It also serves developers through its API, offering two endpoints, one for raw code and another for file uploads, with configurable output formats (JSON or XML) and adjustable complexity levels. It simplifies protection workflows with intuitive, drag-and-drop interfaces and backend API support, empowering users to quickly mask logic, thwart reverse engineering, and secure proprietary scripts without complex setup or tooling.
