Opt-Out Signal Lint for US State Privacy Laws

Runs the same checker as the npm package @readystack/optout-signal-lint on a Node.js runtime that pip installs for you (nodejs-wheel-binaries) - no system Node.js needed. Your files are checked locally.

Finds the ad and analytics code that keeps firing after a visitor’s browser has already sent Global Privacy Control.

Install

optout-signal-lint file

Node 18+. The same 20 rules as the VS Code extension, from a terminal or CI.

Free

• Audits the file you have open — every line against all 20 rules, no key, no limit, no sign-up.
• --rules lists every rule

With a licence ($29 once)

• Sweeps the whole workspace, writes the finding list to CSV, JSON or HTML, and returns a CI exit code so the same leak cannot merge twice.

@readystack/optout-signal-lint --dir ./templates --report html --out report.html
