@readystack/firestore-rules-guard

Firestore Rules Guard

Audits firestore.rules and storage.rules for public access, expired test-mode dates and missing owner checks — 13 rules, line by line, before you deploy.

Install

npx @readystack/firestore-rules-guard file

Node 18+. The same 13 rules as the VS Code extension, from a terminal or CI.

Free

• Audit the .rules file you have open and get every open-access finding with its line number, locally, with no key and no account.
• --rules lists every rule

With a licence ($29 once)

• Audit every .rules file in the workspace in one pass and keep a dated Markdown evidence report you can attach to a review or a customer security questionnaire.

@readystack/firestore-rules-guard --dir ./templates --report html --out report.html

A freelance Firebase developer is quoted at $120 an hour, and a manual pass over one project's rules takes about an hour, repeated every time the rules change.
