You’ll set up a complete beginner coding toolkit for free: editor, Git, AI assist, API testing, and first project deployment.

This guide is for absolute beginners, bootcamp students, and career switchers starting in 2026.

Time to complete: about 30–45 minutes (or 15 minutes for the quick setup path).

Quick Answer

If you want the shortest path, install Visual Studio Code, add Prettier, GitLens, and Live Server, install Git, sign in to GitHub, and create your first repo. Then install Codeium for free AI autocomplete and Postman for API testing. You’ll be ready to build and publish a simple project today.

Why this free starter stack works in 2026

VS Code remains one of the most widely used code editors, and it runs well on beginner laptops. With a few extensions and Git basics, you can write cleaner code, track changes safely, and publish projects without paying for premium IDE tools.

For extra context on current dev-tool usage and beginner stacks, see the Stack Overflow Developer Survey technology section and this roundup of software development tools.

Step 1: Install VS Code and core extensions

  1. Download and install VS Code.
  2. Open Extensions (Ctrl+Shift+X).
  3. Install these beginner essentials:

Expected result check: You can open any project folder, save a file, and see formatting and syntax highlights working immediately.

Step 2: Set up Git and GitHub basics

  1. Install Git from git-scm.com.
  2. Configure your identity in terminal:
git config --global user.name "Your Name"
git config --global user.email "[email protected]"
  1. Create a GitHub account at github.com.
  2. Inside a project folder, initialize Git:
git init
git add .
git commit -m "First commit"

Git documentation for beginners: official Git docs.

Expected result check: You can run git status and see a clean working tree after committing.

Step 3: Add free AI autocomplete with Codeium

Install the Codeium VS Code extension and create a free account on Codeium. You’ll get inline suggestions as you type, which helps with boilerplate and learning syntax faster.

Expected result check: In a new .js or .py file, start typing a function and confirm inline suggestions appear.

Step 4: Install Postman for API testing

Download Postman and create a free workspace. For a first test, send a GET request to a public endpoint like JSONPlaceholder.

Expected result check: You can send a request and see a valid JSON response with status code 200.

Step 5: Build and publish your first mini project

Create a simple index.html + script.js project in VS Code. Use Live Server to preview locally, then push to GitHub and deploy with GitHub Pages.

git add .
git commit -m "Build first mini project"
git branch -M main
git remote add origin https://github.com/your-username/your-repo.git
git push -u origin main

Expected result check: Your project opens in browser locally and also loads from your published GitHub Pages URL.

Common mistakes

  • Installing too many extensions at once: Start with 3–5 essentials to keep VS Code fast.
  • Skipping Git identity setup: Commits may fail or show wrong author details.
  • Forgetting first commit before push: Empty repos can confuse beginners.
  • Assuming AI suggestions are always correct: Review Codeium output before accepting.

Troubleshooting

  • Git command not found: Reinstall Git and restart terminal/PC.
  • VS Code extension not activating: Reload window (Ctrl+Shift+P → “Developer: Reload Window”).
  • Push rejected: Pull latest changes first or verify remote URL and branch name.
  • Live Server not opening: Check firewall prompts and ensure port is not blocked.
  • Postman SSL/proxy issues: Review Postman network settings and test with a known public API endpoint.

Best free developer tools for beginners 2026: final setup checklist

  • VS Code installed and configured
  • Core extensions active (Prettier, GitLens, Live Server, bracket highlighting)
  • Git + GitHub working with successful commit and push
  • Codeium suggestions running in editor
  • Postman request tested successfully
  • First project published on GitHub Pages

If you complete this checklist once, your next projects become much faster and less overwhelming.
