Your code.
Their confusion.
By design.
The first JavaScript obfuscator built specifically to defeat AI-assisted reverse engineering. Not just hidden โ weaponized against analysis.
Static analysis gets an answer. Just not the right one.
Your JavaScript is wide open
Every line of JavaScript you ship is readable by anyone โ competitor, attacker, or AI. Your pricing algorithms, license checks, and business logic are a browser DevTools away. That stops today.
Live demo: watch an attack fail in real-time
โResists Tokenizer-Based AI Analysis
Modern LLMs deobfuscate traditional protection in minutes. They understand renaming, string decoding, and control flow โ making conventional obfuscation useless.
JSGuardian is AI-resistant by design. Analysts get convincing false results. The analysis succeeds โ but the output is wrong. Your attacker is confident and incorrect.
Analysts Get Convincing False Results
Attackers extract your license validation, generate keys, and distribute cracked versions. Your revenue disappears while your code does the work.
Deception-first architecture: attackers extract a mathematically convincing shadow function that produces plausible results โ all of which fail in production.
Logic Is Never Visible in Static Analysis
Your pricing algorithms, recommendation engines, and business logic shipped in JS are readable to any developer who opens DevTools.
Zero static key material. Your protected code contains nothing readable about its decryption. The logic is only visible at runtime โ inside an interpreter that cannot be extracted.
Offline Analysis Fails โ Keys Derived at Runtime
Automated scanners run your JS in sandboxes with frozen clocks. They expect to see the same code behavior that production users see.
Keys derived at runtime โ offline analysis fails. Sandboxed environments get a different key than production. They decode garbage. The active misdirection layer ensures they don't know it.
The obfuscator that fights back.
Tested against 6 generations of iterative red-team analysis. Architecture reviewed against every known deobfuscation tool.
Deception layer verified to produce analyst-grade false positives. No two protected builds are identical.
Watch the misdirection work.
Each layer is a distinct trap. Click any to see how analysts get the wrong answer โ confidently.
JsGuardianVM
Your functions become an alien language
Every layer of analysis
leads deeper into misdirection.
13 independent layers. Each targets a different attack vector โ tokenizer, AST, execution, and AI analysis levels simultaneously. Analysts don't hit a wall. They get a convincing wrong answer.
Sealed Runtime Execution
Logic executes inside a sealed runtime โ never exposed as JavaScript. No static disassembler exists for this instruction set.
Constant Obfuscation
Every number in your code becomes an unfoldable expression. Constant-folding tools produce no useful output.
Zero Static Key Material
Decryption keys are derived at runtime. No file analysis โ however deep โ produces the real answer offline.
Tamper Detection
The file is incomplete by design. Any modification breaks the integrity chain โ silently, without crashing.
Environment-Aware Behaviour
Behaves differently in analysis environments โ automatically. Detection logic is inside the runtime, unpatchable from outside.
Deception Output Layer
Analysts find what looks like the answer โ it isn't. Confident wrong results are better for you than no results at all.
Tokenizer-Level Attack
Defeats automated tools that can't see what they can't read. Attacks the tokenizer, AST parser, and LLM attention simultaneously.
Runtime-Sensitive Keys
Protection changes based on runtime conditions an offline analyst can never replicate. Sandbox output is silently wrong.
Context Window Flooding
AI analysis context is exhausted before reaching real code. The analyst doesn't know they ran out of runway.
Ghost Trail Injection
Reverse engineers chase ghosts while your real logic stays hidden. Scanner tools trigger on the bait, not the code.
Tooling Assumption Breaker
Breaks deobfuscator assumptions at the AST level. Formatters, linters, and normalizers produce incorrect output.
Daily-Rotating Protection
Protection that changes daily without touching your code. Yesterday's analysis produces today's garbage.
AI Refusal Triggers
Cautious AI tools refuse to analyse further. Non-cautious tools waste their budget on convincing decoys.
Protected in 60 seconds.
Upload Your Files
Drop .js files or a .zip archive. JSGuardian handles any project structure โ your monthly quota is measured by output KB, not file count.
Choose Protection Level
Select a preset or customize all 13 layers individually. Every run uses a unique random seed โ no two outputs are identical.
Download Protected Code
Download individual files or a complete ZIP. Protected code runs identically to the original.
One click. Full misdirection stack.
Pick a preset or tune every layer individually. Each run uses a cryptographic random seed โ no two outputs are ever identical.
Obscure
Fast. No readable constants or strings. Logic harder to follow.
- Constants unfoldable
- Zero readable strings
- Runtime-born keys
- Environment-aware
Deceive
Full deception stack. Analysts get confident wrong answers.
- Everything in Obscure
- Logic sealed in runtime
- Deception output layer
- Context window flooding
- Daily-rotating protection
Maximum
Every layer at full strength. The full misdirection architecture.
- Everything in Deceive
- Ghost trail injection
- Tooling assumption breaker
- All 13 layers active
Stealth
Maximum protection. No visible markings. Blends completely.
- Everything in Maximum
- No copyright markers
- Indistinguishable from unlicensed JS
Not just obfuscation. Active defense.

Anthropic's most capable generally available model attempted to deobfuscate a JSGuardian-protected file โ under black-box, adversarial conditions. This is what happened.

๐ฌ Analysis Attempts โ What Failed
๐ What Makes JSGuardian Different
Manipulates AI reasoning โ injected prompts cause LLM refusal before analysis begins
Corrupts ML pattern matching โ adversarial poisoning defeats deobfuscation models
Wastes analyst capacity โ credential honeypots redirect both AI and human effort
Invalidates offline analysis โ time-derived keys prevent static key recovery
Defeats symbolic execution โ intentionally broken primitives corrupt reasoning chains
"Full deobfuscation was not achieved. Source code was not recovered."
The fact that Anthropic's most capable model refused multiple times, failed to recover the source, and encountered layers it will not disclose is the most credible endorsement this tool could receive.
