JavaScript Protection Platform
Protect production JavaScript with a workflow your team can actually ship.
JavaScript Obfuscator hardens generated JavaScript against inspection and copying, then scales from a fast online test to desktop, API, and repeatable release workflows.
Modern JS Ready
Protect generated output from TypeScript, JSX, modules, and framework builds.
Desktop + Web + API
Use the browser for speed or desktop and API workflows for repeatable jobs.
VM-Aware Guidance
Know when layered obfuscation is enough and when bytecode or runtime defenses matter.
Protection Preview
Readable in, protected out.
See how quickly clear application logic turns into difficult-to-reverse protected output.
Input
function validateLicense(plan) {
if (plan === 'trial') return false;
return plan.expiresAt > Date.now();
}
Protected
function _0x7f1a(_0x2a9d){
return _0x2a9d!==_0x57('trial')
&& _0x2a9d[_0x57('expiresAt')]>Date.now();
}
-
✓
Batch processing — protect complete projects in one pass with the desktop app.
-
✓
Embedded JS support — secure JavaScript inside HTML, PHP, ASP, ASPX, and JSP files.
-
✓
Layered hardening — combine mangling, encoding, compression, and locking options.
Used across web, embedded, and enterprise JavaScript projects since 2008
Web & SaaS
Protect dashboards, licensing checks, and proprietary front-end logic before release.
Embedded & Server-Rendered
Harden JavaScript inside HTML, PHP, ASP, ASPX, and JSP templates with the desktop workflow.
Build & CI Pipelines
Drop the command-line and API workflow into existing release jobs for repeatable protection.
Fast Start
Paste code into the online obfuscator and ship protected output in minutes.
Great for experiments, demos, and one-off jobs.
Desktop Control
Move bigger workflows into the desktop app when you need repeatable project protection.
Ideal for embedded JavaScript and bulk processing.
Safer Releases
Reduce exposure of business logic, licensing checks, and proprietary front-end code.
Built to preserve behavior while increasing resistance to inspection.
Proof And Trust
Competitors often win trust by publishing clearer diligence material. This site now exposes the hosted-versus-local workflow, protected-build validation process, compatibility guidance, and honest runtime-defense boundaries in one place.
- ✓
Review when to use the browser, API, npm CLI, or local desktop workflow based on source-handling requirements.
- ✓
Use exclusion rules, protected-output smoke tests, browser checks, and release-check preflights before deployment.
- ✓
See where obfuscation helps, where runtime monitoring is separate, and why server authority still matters for high-risk logic.
Built for Real Projects
Turn readable source code into protected output that is much harder to analyze, while keeping pricing, desktop workflows, and release automation clear enough for a team to adopt quickly.
- ✓
Make logic, identifiers, and strings significantly harder to follow in shipped bundles.
- ✓
Protect generated JavaScript after Vite, Webpack, Rollup, TypeScript, JSX, or framework compilation.
- ✓
Use the desktop workflow to protect JavaScript embedded in server-rendered templates and mixed files.
Why Teams Choose It
The site now tells a sharper story: practical obfuscation, clear VM/bytecode guidance, workflow proof, and honest runtime-defense boundaries.
Transform readable JavaScript into output that is much harder to understand, reuse, or modify.
Reduce JavaScript payload size and help applications load faster while adding protection to shipped code.
Designed to preserve runtime behavior while reducing exposure and supporting modern ECMAScript.
Add stronger protection with domain restrictions, trials, and additional release controls.
Protect full projects quickly, including JavaScript embedded in HTML and similar files.
Know where obfuscation helps and where high-risk applications should add monitoring, anti-debugging, or server-side controls.
How It Works
Whether you start in the browser or the desktop app, the workflow is straightforward and designed to be repeatable.
Use the online obfuscator for speed or the desktop app for larger project batches and embedded JavaScript.
Combine obfuscation, mangling, string encoding, compression, and locking options based on your release needs.
Deploy output that keeps application behavior intact while making client-side logic harder to inspect and reuse.
Modern Workflows
The platform is built for teams that want protection after their JavaScript assets are generated, not just a one-off browser demo. Use the online tool to test quickly, then move into the desktop, API, and command-line workflow for repeatable releases.
Protect the JavaScript files your existing frontend build already emits, whether they came from React, Vue, Node.js, or another toolchain.
Use the desktop workflow when your shipped JavaScript lives inside HTML, PHP, ASP, ASPX, JSP, or similar mixed files.
Store your project settings in the desktop app, then generate the command line used by your release script or CI job.
Use Variable Exclusion plus cross-file options so public names, framework integrations, and shared identifiers stay compatible.

ECMAScript Compatible
Protect generated JavaScript from modern TypeScript, JSX, module, and framework builds after your existing compiler has produced deployable assets.
Desktop App
Protect whole projects in one pass — including JavaScript embedded in HTML, PHP, ASP, ASPX, and JSP. The desktop app handles batches the browser tool cannot.
