getreadystack/erb-escape-audit repository overview

⁠ERB Escape Audit - Rails XSS lint

15 rules that find every line in a Rails .erb view where output escaping was switched off or was the wrong escaping.

⁠Run

docker run --rm -v "$PWD":/work getreadystack/erb-escape-audit /work/file

The same 15 rules as the VS Code extension, in a container. Mount a folder on /work.

⁠Free

• Audit the .erb file you have open: every unescaped-output line with its line number, severity and the escaping helper that fixes it - no key, no cap, no watermark.
• --rules lists every rule

⁠With a licence ($29 once)

• Sweep every .erb file in the workspace in one run and write a dated Markdown/CSV report you keep as the evidence artefact for a release note or a vulnerability-handling record.

docker run --rm -e READYSTACK_LICENSE=<key> -v "$PWD":/work getreadystack/erb-escape-audit --dir /work --ci

A freelance Rails developer doing the same template review by hand bills $75-$150 an hour.
