BaaS security
Backend-as-a-Service platforms — Supabase, Firebase, Clerk, Auth0 — handle the parts of an app that AI coding tools touch least carefully: row-level security, storage rules, identity provider configuration, and which keys ship to the browser. This section is a focused library of articles on what those misconfigurations actually look like in production and how to find and fix them. Each article ends with a one-click scan of your own deployment.
// supabase rls scanner
Supabase RLS scanner: find tables with missing or broken row-level security
What a passive RLS scan can prove from outside the database, the four shapes of broken RLS that AI coding tools generate by default, how the FixVibe
baas.supabase-rlscheck works, and the exact SQL to apply once a missing policy is found.Scan your app for missing RLS →
// service role key exposure
Supabase service role key exposed in JavaScript
What the service role key is, why it must never live in the browser, and the three ways AI coding tools accidentally ship it to production. Includes the JWT shape that identifies a leaked key, an immediate-response runbook, and how the FixVibe bundle scan catches it.

// storage hardening
Supabase storage bucket security checklist
A focused 22-item checklist for hardening Supabase Storage — bucket visibility, RLS policies on the
objectstable, MIME-type validation, signed-URL handling, anti-enumeration measures, and operational hygiene. Each item is one item you can finish in 5-15 minutes.Scan public buckets and anon-listable storage →
// firebase rules scanner
Firebase rules scanner: find open Firestore, Realtime Database, and Storage rules
How a Firebase rules scanner works from the outside, the test-mode patterns AI tools generate, the three Firebase services that each need their own rule audit (Firestore, Realtime Database, Storage), and what a scan can prove without credentials.

// rule syntax explainer
Firebase allow read, write: if true explained
What the
allow read, write: if true;rule actually does, why Firebase ships it as the test-mode default, the exact behaviour an attacker sees, and the four ways to replace it with a production-safe rule. Includes a copy-paste audit query and a five-step remediation plan.Scan your production URL →
// clerk hardening
Clerk security checklist
A 20-item checklist for hardening a Clerk integration — environment-key hygiene, session settings, webhook verification, organization permissions, JWT-template scoping, and operational monitoring. Pre-launch and ongoing items grouped by area.
Check auth/session misconfigurations →
// auth0 hardening
Auth0 security checklist
A 22-item Auth0 audit covering application type and grants, callback / logout URL allowlists, refresh-token rotation, custom-action security, RBAC and resource servers, anomaly detection, and tenant log monitoring. Catches the items AI-generated SaaS apps consistently miss.

// umbrella scanner
BaaS misconfiguration scanner: find public data paths across Supabase, Firebase, Clerk, and Auth0
Why BaaS providers fail security in the same shape, the five misconfiguration classes every BaaS-backed app needs to audit, how the umbrella FixVibe BaaS scan works across all four providers, the side-by-side comparison of what each scanner can prove, and an honest comparison to Burp, ZAP, and SAST tools.
