and collecting independent evidence of the project’s real-world professional usage and impact.

If you use JavaScript Obfuscator in a company project — especially at a well-known company, large organization, or widely used product — I would be very grateful if you could contact me.

Helpful evidence may include a brief confirmation or, ideally, a 1–2 page reference letter describing:

how your team or company used JavaScript Obfuscator; what problem it helped solve;

whether it was used in production or an important internal workflow;

I can provide a simple draft/template to make this easy. [email protected]

🚀 Obfuscator.io with VM Obfuscation VM-based bytecode obfuscation

to this package - your JavaScript functions are compiled to custom bytecode that runs on an embedded virtual machine. Each build produces unique opcodes and VM structure, making reverse engineering and automated deobfuscation dramatically harder. ✅ variable/function renaming

✅ + VM-local symbols never exposed as JavaScript ✅ string array + base64/rc4

(runtime-computed jump targets), output is still JavaScript

(base64/rc4 on extracted strings) (per-instruction encoding),

(whole bytecode array as single block) (freezes browser DevTools)

(multi-layered anti-debugging and anti-analysis defenses)

(multi-layered tamper detection, anti-hooking, anti-reverse-engineering protection)
