🚀 Use Cases: Project Blueprints & Tech Stacks
This section serves as a catalog of practical project blueprints. The goal is to demonstrate how the various architectural layers, tools, and patterns we've discussed can be assembled in different combinations to create a wide variety of real-world applications. Think of this as a menu of possibilities, designed to provide inspiration and a tangible starting point for your own projects. Each example illustrates a different set of choices and trade-offs, showing the versatility of the modern development ecosystem.
The Core Technology Stack: A Summary
Before diving into specific examples, here is a summary of the key categories of tools you will see combined in the blueprints below. Understanding these roles is the key to designing your own custom stacks.
- Fullstack Builder: The main chassis of the application.
- Examples: Next.js, Astro, Remix, SvelteKit
- Authentication: The user identity layer that handles sign-up, login, and security.
- Examples: Clerk, Auth.js, Supabase Auth, Stytch
- Data Layer: The application's memory, where information is stored and retrieved.
- Examples: Headless CMS (Sanity, Contentful), Serverless SQL (Neon, PlanetScale), BaaS (Supabase), Vector DB (Pinecone)
- Styling: The tools used to define the visual look and feel of the application.
- Examples: Tailwind CSS, Component Libraries (Mantine, shadcn/ui)
- AI Integration: Services for adding intelligence and machine learning features.
- Examples: OpenAI/Anthropic APIs, Replicate (for running open-source models)
- Deployment & Infrastructure: The platforms that host your application and make it live on the internet.
- Examples: Vercel, Netlify, Railway, Fly.io
