StackShield is a pre-launch safety net for apps you've shipped fast with vibe-coding tools like Lovable, Bolt, v0, Cursor, or Replit. Connect your Supabase, GitHub, or Vercel — one of them or all three — and it runs the simple checkups that catch the boring stuff (leaked keys, broken RLS, open CORS) before your first real user does. Not a full pentest — just the basics, done before you go live.
Connects to the surfaces you already use
StackShield isn't a dashboard you have to learn. It's an agent you turn on, watch, and verify.
One surface or all three. Database only? Fine. Just the repo? Also fine. StackShield scopes to what you authorize.
A live terminal streams every check, finding, and patch. No mystery. No black box.
Every change is atomic, reversible, and recorded. Audit-ready out of the box.
Step-by-step instructions to confirm each fix inside Supabase, GitHub, and Vercel — no trust required.
When you build fast with an AI tool, the boring security basics are what get missed — RLS left off, an API key pasted into a component, CORS wide open. StackShield runs the simple checks before launch so those don't ship with you.
No silent merges. No mystery diffs. StackShield shows you what it changed, why, where, and how to roll back — in plain language.
Remediation Receipt
all resolved| Target | Before | After |
|---|---|---|
| public.profiles | RLS Disabled | RLS Enforced |
| public.orders | Anon SELECT | Admin Only |
| Checkout.tsx | Key Exposed | PR Opened |
| vercel.json | CORS: * | Strict CORS |
Run your first pre-launch scan in under two minutes — even if all you've got so far is a Supabase project with the RLS toggle still off.
