Stop Building Multi-Tenant SaaS From Scratch. I Open-Sourced My Foundation. 🚀

We’ve all been there. You start a SaaS project, and within a week, your auth logic is a spaghetti mess of if (user.orgId === ...) checks. Scaling feels like walking through a minefield.

I decided to fix this once and for all. Meet FlowStack (organization-v2).

🏗️ The Vision: Boring is Better

I didn't want a "magic" framework that hides everything. I wanted "Boring Code." Code that is explicit, predictable, and scales without breaking your brain.

⚡ The Engine (Hono + Bun)

A lightning-fast API built on Bun and Hono. No cold starts, just raw performance.

🔐 Multi-Org Isolation: The "Zero Leak" Promise

Most boilerplates fail at multi-tenancy. FlowStack wins.
Using a custom Organization Isolation logic, we ensure that:

• Member Management: Invite teammates with specific roles.
• Tenant Boundaries: Your sessions, users, and organizations are strictly separated at the database level.

🔑 Authentication Reimagined

Powered by better-auth, we integrated enterprise-grade extensions:

• 📩 Magic Links & Invitations via Zepto Mail.
• 🔄 Password Recovery with secure token flows.
• 🏗️ Multi-Step Onboarding wizard.

🎨 The Tech Stack (2026 Edition)

• ⚛️ Frontend: React 19, Vite 7, TanStack Start, Tailwind 4.
• 🔥 Backend: Hono + Bun.
• 📐 ORM: Drizzle (Type-safe SQL) on PostgreSQL.

🚀 Get Started in 60 Seconds

Don't waste weeks setting up your auth and db layers.
