What Is a Tech Stack?
A tech stack is the set of technologies a website or app is built with. It has four parts: the frontend users see, the backend that runs it, the database that stores data, and the hosting that serves it.
Reality Shifting Tech, a Philadelphia web development and AI agency, builds on Next.js, React, Node, PostgreSQL, and Vercel. A proven stack means a faster site, easier security, and lower long term costs.
The four parts of a stack
- Frontend. What users see and click. The pages, buttons, and layouts.
- Backend. The logic that runs behind the scenes. Logins, payments, and rules.
- Database. Where your data lives. Customers, orders, content, and records.
- Hosting. The servers that deliver your site to the internet, fast and always on.
Common stacks
- Next.js + React. The frontend that powers fast, modern websites.
- Node. The backend runtime that handles requests and logic.
- PostgreSQL. A reliable database that scales with you.
- Vercel. Hosting built for speed, with deploy and rollback built in.
Why the stack matters
- Speed. A slow stack loses customers before they even read your page.
- Security. Proven tools get patched fast. Obscure ones leave you exposed.
- Cost. A stack that is easy to maintain and hire for costs less for years.
Frequently asked questions
What is a tech stack in plain English?
It is the list of tools a website or app is built with. Think of it like the parts of a car: the body people see, the engine that does the work, the fuel tank that stores energy, and the road it drives on. Frontend, backend, database, and hosting.
What are the four parts of a stack?
The frontend is what users see and click. The backend is the logic that runs behind the scenes. The database stores your data. The hosting serves everything to the internet. Every app has all four, even if one tool does double duty.
What stack does Reality Shifting Tech use?
Next.js with React on the frontend, Node on the backend, PostgreSQL for the database, and Vercel for hosting. It is fast, secure, and easy to maintain, which keeps your long term costs down.
Why does the stack matter?
Because it decides three things you will feel every day: how fast the site loads, how easy it is to secure, and how much it costs to change and maintain later. A good stack saves money for years.
Who decides what stack to use?
Your development team should. A good team picks proven tools that fit your project and are easy to hire for later. You should not have to think about it, but you should be able to ask why.
Can I switch stacks later?
Yes, but it is expensive and slow, so it is worth getting right the first time. That is why the initial choice matters more than it looks like from the outside.
