Facts

Purpose: Obfuscator.io transforms JavaScript into harder-to-read code, including custom bytecode that runs in an embedded JavaScript virtual machine.obfuscator.io · 29 Sept 2026
Standard obfuscation: Standard obfuscation runs in the browser, is always free with no limits, and the playground says submitted code never leaves the device.obfuscator.io · 29 Sept 2026
VM defenses: VM obfuscation offers self defending and debug protection features, including integrity checks, hook detection, breakpoint neutralization, and environment fingerprinting.obfuscator.io · 29 Sept 2026
Code targeting: Users can select individual functions for VM obfuscation by marking them with a comment and configuring the target functions mode.obfuscator.io · 29 Sept 2026
Integrations: The service offers REST API and npm package access, and its API can be called from GitHub Actions, GitLab CI, Jenkins, or any runner with Node.obfuscator.io · 29 Sept 2026
Team workflow: Teams can share presets and service tokens and enforce obfuscator versions and presets across members and builds.obfuscator.io · 29 Sept 2026
Usage metadata: For abuse handling and usage analysis, the service says it retains a SHA-256 hash of each obfuscated output and selected settings for three months, but not the code or its content.obfuscator.io · 29 Sept 2026
Security limit: The maker cautions that frontend secrets can be extracted and says obfuscation is not encryption or a guarantee against reverse engineering.obfuscator.io · 29 Sept 2026
Compatibility: The output is actively supported and tested on evergreen desktop browsers and iOS 16 or later; older browser support is best effort down to ES2015 module support, with Internet Explorer out of scope.obfuscator.io · 29 Sept 2026
Supported inputs: The documentation says to compile TypeScript and JSX and bundle applications before obfuscation, and the site supports HTML files through its HTML parsing option.obfuscator.io · 29 Sept 2026
Limitations: VM obfuscation may not work correctly with all input code or runtime environments, and the terms require users to test obfuscated code before production use.obfuscator.io · 29 Sept 2026
Support: The site lists [email protected] as its support contact and includes priority support with Business.obfuscator.io · 29 Sept 2026
Usage restriction: The terms prohibit using the API to operate an obfuscation SaaS or online tool for third parties, or reselling or white-labeling the service.obfuscator.io · 29 Sept 2026
