Difference between Git and Github ?

Overview

Git is a distributed version control system. GitHub is a web-based hosting platform for Git repositories. Think of Git as the tool and GitHub as the service that uses the tool.

Git — Local Version Control

bashCopy
# Git is used locally on your machine
git init                    # Create a new local repo
git add .                   # Stage changes
git commit -m "Add login"   # Save snapshot locally
git branch feature/auth     # Create branch
git merge feature/auth      # Merge branch
git log                     # View commit history

All of this works without GitHub — purely on your local machine.

GitHub — Remote Hosting + Collaboration

GitHub adds on top of Git:

bashCopy
# Push local repo to GitHub
git remote add origin https://github.com/user/repo.git
git push origin main

# Pull latest changes from GitHub
git pull origin main

# Clone a GitHub repo
git clone https://github.com/flutter/flutter.git

The Full Workflow

textCopy
Local Machine (Git)              GitHub (Remote)
─────────────────                ──────────────────
git init                         
git add + git commit   ──push──▶  Remote repository
                       ◀─pull──   (shared with team)
git branch             ──PR───▶   Pull Request → Review
git merge              ◀─────     Merge on GitHub

One-line summary: Git is the tool you install on your computer to track changes. GitHub is the website where you store and share your Git repositories with your team.
