PrivacyThe service states that VM and HTML requests are processed on its servers and discarded after processing, while basic JavaScript obfuscation runs in the browser.The playground runs locally in the browser, including offline, and says code and user actions are not sent to a remote server.
PurposeJavaScript Obfuscator transforms JavaScript into harder-to-understand code to protect source code.JS-Confuser obfuscates JavaScript to make code harder to understand, copy, reuse, or modify while preserving its functionality.
Security limitationThe documentation says obfuscation is not encryption and advises against storing API keys, secrets, or credentials in frontend code.The FAQ says determined reverse engineers may eventually deobfuscate code and extract secrets or bypass client-side checks.

JS-Confuser

JS-Confuser obfuscates JavaScript to make source code harder to understand, copy, reuse, or modify while preserving its functionality. Its browser playground accepts pasted code, lets users choose settings, and produces a downloadable result. The playground runs in the browser, including offline, and says it does not send code or actions to a remote server. Users can start with Low, Medium, or High presets or create custom configurations. Options include renaming variables, concealing strings, flattening control flow, inserting dead code, setting domain or date locks, and tamper protection. The API offers JSConfuser.obfuscate for source code and JSConfuser.obfuscateAST for Babel ASTs; output targets include Browser and Node.js. The editor includes Prettier and a JSON representation of JSConfuser.ts settings. JS-Confuser is described by its maker as free and open source. Obfuscation can increase file size and performance overhead or break a program, and it cannot prevent determined reverse engineers from recovering code or sensitive information. Tamper protection requires eval and non-strict mode.
