Turn readable JavaScript into something nobody wants to reverse-engineer.

SaurusEnc runs the same obfuscation pipeline built for protecting WhatsApp bot logic, packaged as a standalone tool. Paste your source, choose how far to go, get back code that still runs.

$ loading js-confuser engine...

$ engine ready — same core used in Saurus's Baileys bot

$ paste source, pick a preset, run

01 — choose a preset

02 — source in, cipher out

How it works

Paste or upload

Drop in a .js file or paste source directly. Everything runs server-side per request — nothing is stored.

Pick your transforms

Three presets cover most cases, or open Custom to toggle string encoding, flattening, and renaming individually.

Ship the cipher

Output is valid, runnable JavaScript — copy it straight into your bot, API, or client bundle.

Built on js-confuser, the same open-source engine wired into Saurus's Baileys-based WhatsApp bot for protecting plugin source before distribution. This site exposes that pipeline directly — no bot required.
