THE ARCHITECTURAL PROBLEM

WHY DO MOST SAAS ARCHITECTURES FAIL AT SCALE?

Relying on manual WHERE tenant_id filters in application code inevitably causes confidential data leaks. TidyFactor Next establishes database-level RLS boundaries and lean RSC execution.

Fragile Custom SaaS Setup

✕ Brittle application-level filtering risking catastrophic customer data leaks.
✕ Months spent reinventing tenant resolution, auth, RBAC, and storage buckets.
✕ Sluggish local development loops with bloated memory footprint and slow HMR.
✕ Hard vendor lock-in preventing easy database layer migration or scaling.
