Claude Code

What it is: A terminal-based coding agent by Anthropic. You describe what you want, and it reads your codebase, writes files, runs commands, debugs, and deploys — autonomously.

How to start:

Install: npm install -g @anthropic-ai/claude-code
Navigate to your project: cd my-project
Launch: claude
Describe your task: "Add a dark mode toggle to the settings page"
Claude reads your code, plans the changes, writes them, and can run tests to verify

Why we use it: Claude Code built this entire 108-site WholeTech Network. Python build scripts, HTML/CSS, server deployment, SSL setup, SEO optimization — all from the terminal. It handles multi-file changes and complex architectures that chat-based tools struggle with.

Best for: Experienced developers who want an autonomous coding partner. Greenfield projects, major refactors, deployment automation, and tasks that span many files.

Limitations: Terminal-based (no visual IDE). Requires some developer knowledge to direct effectively. Uses your Anthropic API credits or Claude subscription.

Cursor

What it is: An AI-first code editor built on VS Code. Everything you love about VS Code plus deep AI integration — inline completions, chat, multi-file editing, and codebase-aware suggestions.

How to start:

Download from cursor.com (Mac, Windows, Linux)
It imports your VS Code settings, extensions, and keybindings automatically
Open a project and start coding — AI suggestions appear as you type
Press Cmd+K (Mac) or Ctrl+K to ask the AI to edit code inline
Press Cmd+L to open the chat panel for longer conversations about your code

Key features:

Tab completion: AI predicts your next edit (not just the next line). It understands what you're trying to do and suggests multi-line changes.
Cmd+K inline editing: Select code, describe the change ("add error handling"), and Cursor rewrites it in place.
Codebase chat: Ask questions about your entire codebase. "Where is authentication handled?" — it finds and explains the relevant files.
Composer: Multi-file editing mode. Describe a feature and Cursor edits multiple files at once to implement it.

Pricing: Free tier (limited AI calls). Pro: $20/mo (500 fast requests/mo + unlimited slow). Business: $40/user/mo.

Best for: Developers who want AI inside their editor. If you live in VS Code, Cursor is the natural upgrade. Great for daily coding with AI assistance.

GitHub Copilot

What it is: Microsoft/GitHub's AI pair programmer. An extension for VS Code, JetBrains, Neovim, and more. Suggests code completions as you type, powered by OpenAI's models.

How to start:

Sign up at github.com/features/copilot
Install the GitHub Copilot extension in your editor
Start typing — suggestions appear as ghost text. Press Tab to accept.
Use Copilot Chat (sidebar) for longer questions and explanations

Key features:

Inline completions: Suggests the next line or block of code as you type. Learns your patterns.
Copilot Chat: Ask questions, explain code, generate tests, fix bugs — all in the sidebar.
PR summaries: Automatically generates pull request descriptions from your changes.
CLI: Copilot in the terminal — ask it to generate shell commands.
Workspace agent: @workspace lets you ask questions about your entire repository.

Pricing: Free (for verified students, teachers, and open source maintainers). Individual: $10/mo. Business: $19/mo. Enterprise: $39/mo.

Best for: Developers who want lightweight AI assistance without changing their editor. Works in the editors you already use. The most popular AI coding tool by user count.

Replit

What it is: A browser-based IDE with built-in AI. Write, run, and deploy code without installing anything. The AI assistant can generate entire applications from descriptions.

How to start:

Go to replit.com and sign up
Click "Create Repl" and choose a language/template
Use the AI assistant to generate code: "Build a to-do app with user authentication"
Code runs in the browser. Hit the Deploy button to publish it live.

Best for: Beginners, students, rapid prototyping, hackathons. No local setup, no environment issues, no deployment complexity. Just describe and build. Also great for trying out new languages or frameworks quickly.

Pricing: Free (limited). Hacker: $7/mo. Pro: $25/mo (better AI, more compute). Teams available.

Which Should You Use?

You're building a big project from scratch

Claude Code. It handles multi-file architecture, writes build scripts, deploys, and can work autonomously on complex features. The most capable for greenfield development.

You code every day and want AI in your editor

Cursor. It's VS Code with superpowers. The inline editing (Cmd+K) and multi-file composer are best-in-class for daily development work.

You want lightweight help without changing tools

GitHub Copilot. Installs into your existing editor. Unobtrusive. Suggests as you type. The easiest to adopt. At $10/mo, it's also the cheapest.

You're learning or prototyping quickly

Replit. No setup. Browser-based. AI generates entire apps. Deploy in one click. The lowest barrier to going from idea to running code.

Pro move: Many developers use multiple tools. Claude Code for big features and architecture, Cursor or Copilot for daily editing, and Replit for quick experiments. They're complementary, not mutually exclusive.
