Configless Stack
Write Code,
Not configrations.
Write code, Deploy. No configurations needed. No build issues found. No forgotten envs. Perfect for production.
Join us for the kickoff brainstorm!
Will be meeting 9AM CST on Tuesday to go over engineering details for initial version. Feel free to join at https://t.co/a52EQRJ1O7 would love to hear from everyone on this OSS idea. pic.twitter.com/m5BgSP6vP4

Runtime Magic
factiii/core ingests your Prisma folder and auto-extends auth.
Instant Scaffold
npx @factiii/stack generates a pre-wired T3 app in seconds.
Modular Power
Code-only adapters handle integrations—from OpenAI to Next.js.
Everything you need, nothing you don't.
Focus on your product. Let the configless stack handle the infrastructure complexity.
Schema Ingestion
Stop wrestling with auth tables. factiii/core ingests your schema.prisma, automatically extending it with User tables, associations, and 2FA/email verification logic.
tRPC Export
Forget boilerplate wiring. The core exports a fully typed tRPC router derived directly from your models and routes. You write the logic; we handle the plumbing.
Adapters Flow
A 5-step magic loop: Ingest Code → Validate → Generate Configs → Hook Core → Seal Bundle. Your code is the only source of truth.
Scalable Deploys
Built for Vercel. Optimized for Next.js serverless and edge functions. The configless runtime seals your environment for safe, scalable production releases.
How It Works
From idea to production in three simple steps.
Write Code
Focus on your features. Define routes and models without worrying about the glue code.
// src/server/api/routers/example.ts
export const hello = publicProcedure.query(() => {
return { greeting: "Hello from factiii core" };
});Scaffold & Init
Launch a production-ready stack with one command. No config tweaking required.
npx @factiii/stack@latest my-appDeploy
Push to Vercel. Adapters ingest your code, generate next.config.js, and seal the bundle for instant, zero-config deployment.
Adapters Coming Soon
Fully open source adapters. Anyone can build and contribute their own.
Next.js Adapter
/app → configs
Drop code into your /app folder. The adapter reads your structure and auto-generates the optimal next.config.js.
Expo Adapter
Mobile-first magic
Seamlessly integrate with Expo projects. The adapter handles app.json generation and native module configuration automatically.
tRPC Backend Adapter
Type-safe APIs
Auto-generate fully typed tRPC routers from your Prisma schema. Zero boilerplate, maximum type safety.
