Wrap your code in layered self-defense — integrity hashing, debugger traps, DevTools detection, and a self-destruct that fires the moment someone tampers. SEO-safe by default.

(new Function(_dec(_0x9c,_0xK)))();})();An AST-based engine rewrites your code; runtime defenses arm the moment it loads; access locks gate by time, geography, network, and device — every feature on every plan.
Scope-aware identifier rename, control-flow flattening into state-machine switches, dead-code injection, and function-body wrapping. Linear logic becomes unreadable dispatch tables.
Misleading identifier names like validateJwtToken and computeKeyFingerprint poison the semantic anchors that GPT-class models use to deobfuscate. On for every build.
FNV-1a integrity hash over the encoded payload. Any byte change trips an immediate self-destruct. Polymorphic launcher structure differs on every build.
debugger statement timing, heartbeat watchdog on resume, window-size delta, console getter side-channel, Function.toString tamper check. Five independent signals.
Detects Puppeteer, Playwright, Selenium, PhantomJS, and headless Chrome. Catches the easy scrapers and decoder farms.
Domain, time-expiry, geo, browser, OS, and IP — six independent gates. Restrict where, when, and on what your code runs. Available on free, pro, business, and enterprise.
Meta, JSON-LD, and semantic HTML untouched by default. Stealth mode hides body HTML inside the encoded payload.
Every defense fires a beacon to your built-in telemetry endpoint. Visualized as bar charts, reason breakdowns, and an event feed — see attacks as they happen.
Connect a personal access token, pick a repo and file, obfuscate, and commit the protected output back — same branch, new branch, or new path. One click.
Official CLI, Webpack 5 plugin, and Vite plugin. Drop a few lines into your config and every npm run build ships protected. Zero manual steps from now on.
The launcher's defense checks are Fisher-Yates shuffled before emission. Two obfuscations of the same source come out structurally different, defeating signature-based deobfuscators.
Strict anti-account-sharing: one device signed in at a time. New logins kick the old device out. 10-minute idle auto-logout. Protects your seat from being resold.

Every plan ships the same self-defending engine, every strictness level, every access lock, the full anti-LLM defense pass, and the REST API + CLI + Webpack / Vite plugins. Higher tiers buy you volume, file size, GitHub round-trip, ZIP batch upload, and priority support.
Cancel any time from the Stripe billing portal. Pro-rated refunds where applicable.
Free and Pro get the same self-defending output. Plans differ only in quota and strictness levels.
Email us — Business is the public ceiling. Custom enterprise quotas are negotiable.
Free tier ships with all detection signals enabled. Upgrade only when you outgrow the quota.
