GitHub is a cloud-based platform used to store, manage, and collaborate on software projects that use the Git version control system.
It provides a central location where developers can store source code, track changes, collaborate with others, and manage the development process of applications, websites, and other software projects.

What Is Git?
Git is a version control system that helps developers track changes made to files over time.
Using Git, developers can:
- Record changes to source code
- Restore previous versions of files
- Work on new features without affecting the main project
- Merge changes from multiple contributors
Git itself runs locally on a computer and does not require an internet connection.
How Is GitHub Different from Git?
Although the names are often used together, Git and GitHub are different tools.
Git
- Is a version control system
- Runs locally on a computer
- Tracks changes to files
- Does not require a cloud service
GitHub
- Is a cloud-based hosting platform for Git repositories
- Stores project code online
- Enables collaboration between developers
- Provides additional project management features
In simple terms, Git manages code changes, while GitHub provides an online platform where Git repositories can be stored and shared.
What Can You Do with GitHub?
GitHub offers tools that help individuals and teams manage software projects.
Common features include:
- Hosting Git repositories
- Tracking issues and bugs
- Reviewing code changes
- Managing project tasks
- Collaborating with multiple developers
- Maintaining documentation
- Automating development workflows
These tools help organize development work and simplify collaboration across teams.
Collaboration Features
One of GitHub’s most important features is the ability for multiple people to work on the same project.
Developers can:
- Create branches for new features
- Submit changes for review
- Discuss proposed changes
- Merge approved code into the main project
This workflow helps teams develop software more efficiently while reducing the risk of conflicts.
GitHub Marketplace
GitHub also provides a marketplace that offers integrations and extensions for additional functionality.
Examples include:
- Continuous integration and deployment tools
- Security scanning services
- Project management integrations
- Monitoring and reporting tools
These integrations can be added to repositories to support different development workflows.
Access and Availability
Because GitHub is cloud-based, repositories can be accessed from anywhere with an internet connection.
Project owners can choose whether repositories are:
- Public, allowing anyone to view the code
- Private, restricting access to authorized users only
This flexibility makes GitHub suitable for both open-source projects and commercial software development.
Summary
GitHub is a cloud-based platform for hosting and managing Git repositories. It combines version control with collaboration, project management, and development tools, allowing individuals and teams to build, maintain, and share software projects more effectively.
