Protect Electron / Node.js Logic with JSVMP

Electron apps and Node CLIs ship JavaScript (or easily recoverable JS). Competitors and unpaid redistributors can unpack app.asar, skim license checks, and clone paid CodeCanyon / Gumroad templates.

JSVMP (via VEILVM) compiles high-value modules into VM bytecode so casual unpacking no longer yields readable business logic.

Good targets

  • License / seat validation
  • Proprietary algorithms inside a CLI
  • Premium feature gates in a sold template
  • Offline watermark or ownership checks

Leave alone

  • node_modules and Electron/Chromium themselves
  • Large UI frameworks
  • Anything that must stay easy for customers to patch via config

Pipeline sketch

src/license.js  →  VEILVM (Pro API)  →  dist/license.protected.js
electron-builder / pkg / nexe packs dist as usual

Pro API: up to 2 MB source per request — see docs.

Pricing reminder

3 free runs/day no sign-up (5 KB/file) · Free 20/mo · Pro $9/mo or $79/year.
