Different strengths for different buyers

The free package leads when a technical owner wants to control every detail. JavaScript Obfuscator leads when a team wants a product workflow: browser testing, desktop projects, batch jobs, account limits, mixed-file support, and help when something needs review.

Decision Point	javascript-obfuscator npm package	JavaScript Obfuscator
Technical setup	Strong Best for technical users who are comfortable installing packages and maintaining configuration.	Strong Online, desktop, and advanced team options are available depending on how much setup your team wants.
Non-technical workflow	Limited Best for teams comfortable editing config and scripts.	Strong Online tool and desktop GUI make protection accessible without writing Node scripts.
Batch and mixed files	Works well for generated JavaScript files; mixed server-rendered files require custom workflow.	Strong Desktop app supports larger project batches and JavaScript embedded in HTML, PHP, ASP, ASPX, JSP, and similar files.
Protection choices	Strong Many settings are available for technical users who want detailed control.	Strong Simple online presets are available first, with deeper desktop and team settings when needed.
Trust model	Strong Open source, public issues, visible history, tests, and community adoption.	Strong Commercial service with account plans, published quotas, support, and a long-running release history under one company.
Protection strength	Static obfuscation of generated JavaScript output.	Strong Maximum mode is built for valuable public JavaScript that needs stronger protection before release.
Resists automated code reading	Limited Because the package is open source and widely used, automated tools have more examples to learn from.	Strong Maximum mode changes protected output across releases, making repeatable automated analysis harder.
