JavaScript Obfuscator renames identifiers, encodes strings, flattens control
flow and compresses output so that shipped JavaScript is difficult to read and
to reuse. It handles modern syntax including classes, modules, optional
chaining, generators and template literals, and can target either ES5 or a
modern runtime.
The Windows app protects source locally: files never leave the machine. It
ships with jso-local, a command line front end for the same engine, so the
same protection can run in a build script or on a CI agent.
A free tier is available. Paid plans unlock the stronger presets and larger
inputs.
