View in Browser — Publish Leak Audit (HTML)

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

24 rules read the .html file you are about to open in the browser and flag every line that behaves differently once the page has a public URL: live API keys, localhost and file:// paths, http:// resources, a leftover noindex.

Install

view-in-browser-leak-audit file

Node 18+. The same 24 rules as the VS Code extension, from a terminal or CI.

Free

• Audit the HTML file you are about to open in the browser: all 24 rules, every finding with its severity, line number and fix. The clean fixture returns 0 findings, the dirty one returns 27. No key, no watermark, no locked answers.
• --rules lists every rule

With a licence ($29 once)

• Scope: one command sweeps every HTML file in the workspace instead of the one in front of you, and writes a dated LEAK-AUDIT.md you keep as evidence — forty pages in one pass instead of forty passes.

@readystack/view-in-browser-leak-audit --dir ./templates --report html --out report.html

In February 2026 a developer reported an $82,000 Google Cloud bill after a key embedded in client-side Google Maps code was taken from the page source; their normal spend was $180 a month.
