The Ultimate SaaS Starter Kit

Motivation

After building dozens of SaaS products, I noticed I was rewriting the same boilerplate code: authentication, billing, team management, and API limits. I created ShipSaaS, an open-source reference architecture to solve this once and for all.

Architecture: Multi-Tenancy Done Right

The platform uses a Row-Level Security (RLS) model on PostgreSQL (via Supabase).

Every database query automatically filters by organization_id.
This ensures complete data isolation between tenants at the database engine level, preventing accidental data leaks.

Features

Authentication: Magic links, Social Login, MFA.
Billing: Deep Stripe integration with webhooks for subscription lifecycles.
Team Management: Invite system, role-based access control (RBAC).
API: Edge-ready REST API with per-tenant rate limiting using Redis.

Impact & Community

Since open-sourcing the core modules:

1,500+ GitHub Stars.
Used by 20+ startups as their foundation.
Featured in "Best Next.js Templates 2024".

This project demonstrates my ability not just to write code, but to design cohesive systems that consider developer experience (DX), security, and monetization from Day 1.
