Triple VM Cipher
Three separate LCG-XOR cipher chains wrap the payload, each with its own 256-byte key stream. Someone has to break all three chains independently before they can even see the obfuscated layer below.
GOBS Pro is the only JavaScript obfuscator that stacks 7 completely independent protection layers. Your code goes in protected. Nobody gets it back out.
Each feature targets a different way people try to read or steal your JavaScript. Together they form a wall that nobody can get through automatically.

A dual-engine pre-pass runs before everything else. It applies variable masking, calculator transforms, opaque predicates and function shuffling. The result gets buried under every protection layer that follows.
Timing traps, Proxy traps, prototype chain checks, webdriver detection, headless Chrome detection, Selenium DOM traps, PhantomJS fingerprints and 14 more. All randomized on every single build.
Every string literal gets pulled into an encrypted array with dual RC4 and Base64 encoding, index shifting, shuffled access wrappers and chained decode calls. Getting string values out of the output is basically impossible.
Your program flow gets restructured into a flat switch-case dispatch loop. The original execution order is encoded in a separate shuffled array. Any static analysis tool or AST parser breaks completely on this.
Blocks of code that look completely real but never run get injected throughout the output. Automated deobfuscators spend all their time on paths that lead nowhere.
Lock your script to specific domains with wildcards or exact matches. Set an expiry date and the script simply stops working after that day. Perfect for licensing JavaScript tools and running controlled trials.
Drop in an HTML file and every inline script gets obfuscated in one pass. CSS gets minified. Comments stripped or kept, your choice. UserScript metadata blocks stay intact and correct.
Save your full configuration as a .gobsproj file. Open it next time and every setting comes back exactly as you left it. All four presets work great out of the box, or adjust every individual option yourself.
Here is exactly what you get with GOBS Pro that no free obfuscator can offer. This is not marketing. These are technical facts.
| Feature | Free obfuscators | GOBS Pro v3.0 |
|---|---|---|
| Number of protection layers | 1 to 2 | 7 independent layers |
| Triple VM cipher | ✗ Not available | Included in Maximum |
| Anti-debug trap count | 0 to 3 | 21 randomized traps |
| Dual-engine pre-pass | ✗ Not available | Included in Strong+ |
| Different output every build | ✗ Fixed output | Always unique |
| Domain lock | Some tools | Full wildcard support |
| Date lock / expiry | ✗ Not available | Included |
| HTML file support | Some tools | Full inline JS support |
| No file size limit | ✗ Usually limited | Unlimited via API |
| Reversible by published tools | Often within minutes | Never reversed automatically |
Every preset produces fully working JavaScript. Nothing breaks. You can switch between them at any time without touching your code.
Fast and light. Works in tight environments with CSP restrictions and eval limitations.
Control-flow and dead code on top of Safe. Good middle ground between protection and file size.
Dual-engine pre-pass, anti-debug traps and RC4 encryption. No automated deobfuscation tool survives this.
Triple VM cipher on top of everything. 8 opaque predicates, double-pass. The hardest JS protection ever built.
Seven stages. Each one buries the previous output deeper. By stage 7, the original source is seven layers down with completely different keys at every level.
Drag and drop or paste JavaScript. Works with .js, .jsx, .mjs, .html, .css files of any size.
Choose from Safe, Balanced, Strong, or Maximum. Or configure every single option yourself and save it as a project file.
The secure API server runs all protection layers and sends back the result. Takes a few seconds even for large files.
Drop the output wherever your original file was. No extra dependencies, no wrappers, nothing else needed.
Real feedback from real developers. These are the people who tried free obfuscators and came to GOBS Pro when they needed something that actually works.
"I tried three free obfuscators before this. Someone reversed every single one within a week. With GOBS Pro Maximum, six months later and nobody has gotten into the code."
"The Domain Lock feature alone is worth it. I sell JavaScript tools and I was tired of buyers sharing the files. Now each copy only runs on the domain they paid for."
"What convinced me was the comparison. Free tools take five minutes to reverse. I tested GOBS Pro Maximum for two days with every deobfuscation tool I know. Nothing worked."
Every common question answered honestly. If something is missing, reach out.
One .exe file. No installation. No Node.js. No dependencies at all.
