Supabase Multi‑Tenant Schema & RLS Policy Pack (15 Production‑Ready Schemas)

Stop wrestling with broken multi‑tenant RLS. Start shipping secure production features fast.

You waste hours stitching together half-working schemas, guessing at RLS rules, and praying you didn’t create a cross‑tenant data leak. You hop between forum posts, docs, and GitHub gists trying to make everything play nicely with Supabase Auth. And every time you deploy, you wonder if some hidden privilege escalation will bite you later.

This pack gives you 15 fully production‑ready multi‑tenant schemas with matching RLS policies, triggers, and functions designed specifically for Supabase. Every schema is plug‑and‑play: drop it into your instance, swap one JWT claim, and your app instantly runs on a hardened, tested multi‑tenant foundation.

What's Included:
- 15 multi‑tenant schemas for real app types: SaaS, e‑commerce, CRM, project management, booking systems, analytics tools, and more
- 45+ RLS policies covering tenant isolation, owner‑based access, nested resource permissions, and safe fallback rules
- 20+ production‑ready Postgres functions for tenant enforcement, claims validation, and secure row attribution
- 15 audit and debug triggers to surface misconfigured RLS before it hits production
- 15 schema seed files for quick local testing
- 10 cross‑tenant leak test scripts to verify isolation before you deploy
- A single installation SQL file that wires everything together in under 2 minutes

These patterns come from real production systems handling thousands of tenants, multiple permission layers, and complex user roles. Every schema and policy has been tested under load, audited for privilege‑escalation paths, and validated against common Supabase Auth misconfigurations.

Who This Is For:
- Solo developers building their first multi‑tenant SaaS and worried about leaking customer data
- Agencies that need consistent, repeatable Supabase tenant setups across client projects
- Teams rewriting fragile DIY RLS rules after hitting security or performance issues in production

Who This Is NOT For:
- Apps that don’t require tenant isolation or user‑level access rules
- Developers who want to hand‑craft every SQL file from scratch

Guarantee: If this pack doesn’t save you at least 6 hours of schema and RLS setup time, reach out for a full refund.
