🆚 T3 vs O3

| Feature | T3 Stack 🧘 | O3 Stack 🫧 | | ------------ | ------------------- | ------------------------------------------------------------------ | | Philosophy | Bleed responsibly | Bleed everywhere | | Tech choice | Stable, proven | Shiny, experimental | | Auth | NextAuth/Auth.js | BetterAuth or Auth.js | | API Layer | tRPC | oRPC | | ORM | Prisma | Drizzle ORM | | Validation | Zod | ArkType | | Runtime vibe | Safe & mindful | YOLO, dopamine-first | | Motto | "Bleed responsibly" | "If you're not bleeding everywhere, you're not trying hard enough" |

🚀 Get started

npx create-o3-app@latest
# or
pnpm dlx create-o3-app@latest
# or
yarn create o3-app
# or
bunx create-o3-app@latest

That's it. Follow the prompts and you'll have a bleeding-edge, type-safe, full-stack app in seconds.

What is this?

The O3 Stack is T3's unhinged sibling. We took everything great about T3 and cranked it up to 11. Where T3 carefully selects proven technologies, we grab the coolest, newest, most exciting tools and smash them together into something beautiful.

The Stack:

• 🔥 oRPC - Because tRPC is so 2023
• 🛡️ BetterAuth or Auth.js - Your auth, your rules
• 🗄️ Drizzle ORM - SQL that doesn't hate you
• ✅ ArkType - Runtime validation that's actually fast
• ⚡ Next.js 15 - Because we live on the bleeding edge
• 🗄️ NeonDB - Who has time to setup a Database ?

Why O3?

We love new shit. That dopamine hit from trying cutting-edge tech? We're addicted. We don't wait for things to be "stable" or "production-ready" – we dive headfirst into the newest, most experimental tools and figure it out as we go.

Type safety is non-negotiable. From your database to your UI, every single piece talks to every other piece with perfect TypeScript inference. No any types. No runtime surprises. Just pure, beautiful type safety.

Modularity by design. Don't want auth? Skip it. Don't need a database? No problem. Every piece is optional, and the CLI generates exactly what you need.

The O3 Philosophy

1. Newer is better - We don't wait for "production-ready"
2. Types everywhere - If it's not type-safe, it doesn't belong
3. Developer happiness - Tools should spark joy, not frustration
4. Modular by default - Use what you need, skip what you don't
5. Community-driven - The best ideas come from developers building real stuff
