Hardware Stacks

Hardware is the physical foundation that runs every software stack. It includes the computers, chips, processors, and devices that actually execute your code.

Most beginners overlook this layer because it stays behind the scenes, but understanding the basics helps you choose the right tools and grow without hitting unnecessary limits.

Main Types of Hardware

Laptop or Phone

Your everyday starting point. Portable, costs nothing extra, and works great for web development, mobile apps, game dev, machine learning, blockchain, and almost everything else.

Cloud Servers

Virtual machines you rent from providers like AWS, Vercel, Google Cloud, or Railway. They can scale massively, and you never have to buy or maintain physical hardware.

Edge Devices

Small dedicated computers such as Raspberry Pi, smartphones, VR headsets, or Arduino boards. Perfect for IoT, robotics, XR, and real-time processing right where the action happens.

Specialized Hardware

High-end GPUs for AI training, or access to quantum processors (many available through free cloud simulators). These are rarely needed at the beginning, but good to know about for future projects.

You Don’t Need Expensive Hardware to Start

A regular laptop plus free cloud tiers is enough for 90% of projects. The software layers do most of the heavy lifting anyway.

Quick Tip

Only worry about special hardware (like a powerful GPU or WebXR support) when your specific project actually needs it. Otherwise, keep it simple and you’ll move much faster.
