Evidence-first Supabase security

Check your Supabase RLS before launch.

Run the same audit I run for clients: 7 commented SQL files and a 60-check workflow that find cross-user and cross-tenant leaks before your users do. Runs against your own database — nothing leaves it.

48-hour launch review$79 · $49 launch · 3 slots

Next.js + Supabase Launch Review

For one launch-ready repository that needs a bounded human review before production.

  • One repository or source ZIP, up to 25,000 relevant lines
  • RLS, secrets, auth, webhooks, monitoring and rollback
  • Five prioritized findings with practical next steps
  • Delivery within 48 hours after usable sanitized materials arrive

Review only—not implementation, a penetration test, legal/compliance advice or a security guarantee. Do not send live secrets or customer data.

Client-delivery workflow$49 · $39.20 launch

AI-Ready Website Audit Kit

  • Canonical evidence ledger and editable client report
  • Implementation templates, 19-page playbook and 16 regression tests
  • Dependency-free Node.js 18+ workflow with manual evidence collection

The public report is synthetic demonstration data. The kit does not promise rankings, citations, traffic, security or revenue. The purchase link applies the existing LAUNCH20 code while its allocation remains.

  • 60 checks across eight structured audit passes
