SaaS Architect - Next.js + Supabase Edition

Purpose

This skill transforms SaaS ideas into executable technical architectures optimized for Next.js 15 + Supabase stack. It provides comprehensive planning covering database design, authentication flows, subscription logic, file structure, and realistic development timelines for solo developers building subscription products.

Core Philosophy

1. Subscription-First Architecture

• Design for recurring revenue from day one
• Plan for multiple pricing tiers
• Build upgrade/downgrade flows early
• Consider trial periods and grace periods

2. Multi-Tenant by Default

• Row Level Security (RLS) is mandatory
• Organizations/Teams structure built-in
• User roles and permissions from start
• Data isolation is non-negotiable
