The GELLIFY Stack
The GELLIFY Stack is a modern web development stack designed for simplicity, modularity, and full-stack TypeScript safety. Created and refined by Matteo Badini↗ and the GELLIFY team, it brings together battle-tested technologies to help developers build scalable, maintainable, and performant applications with minimal friction.
At its core, the stack relies on Next.js↗ and TypeScript↗, providing a robust foundation for full-stack development. For UI, shadcn/ui↗ and Tailwind CSS↗ deliver a flexible and accessible design system. When it comes to backend capabilities, Neon↗ (a serverless PostgreSQL with branching and autoscaling), Drizzle↗ (a type-safe ORM), and Clerk↗ (a managed authentication service) streamline the process of managing data and users effortlessly.
This stack is intentionally modular. Need authentication? Use Clerk. Want a different ORM? Swap out Drizzle. The goal is to empower developers with best-in-class defaults while keeping things customizable.
So… what is create-gellify-app? A template?
Yes! create-gellify-app is more than just a template—it’s a curated starting point for building modular, full-stack applications quickly. Developed from years of experience, it encodes best practices and proven architectural choices into a streamlined, production-ready setup.
Each piece of the stack is optional, allowing you to customize it based on your needs. We’ve distilled countless hours of development into this template, so you don’t have to start from scratch.
This is not a one-size-fits-all solution. You’re encouraged to bring your own tools for things like state management or deployment, but we do offer recommendations based on our experience.
GELLIFY Axioms
We take a strong stance on a few core principles that shape how we build. These guide our decisions and ensure that create-gellify-app remains a reliable, scalable foundation.
🛠 Solve Real Problems
We don’t believe in adding everything for the sake of it. Every tool in create-gellify-app solves a real problem within the core stack. That’s why you’ll find Clerk (authentication) and Neon (database), but not a state management library like Redux—because state management varies widely by project.
⚡ Bleed Responsibly
We love using cutting-edge technology—but we do it wisely. We won’t gamble on unproven database tech (SQL works great!), but we do embrace innovations like shadcn/ui, which can be swapped out easily. Our philosophy: experiment where it’s safe, be pragmatic where it matters.
🔒 Typesafety Is Non-Negotiable
Typesafety isn’t just a feature—it’s a core value. create-gellify-app is built to ensure a fully type-safe experience, minimizing bugs and maximizing productivity. If a decision compromises TypeScript safety, it doesn’t belong here.
Why We Built This
At GELLIFY, we’ve worked on countless projects, refining our approach over time. This stack is the result—a developer-friendly, production-ready foundation that lets you focus on building great products instead of wrestling with setup and architecture. 🚀
