GitHub (GH)

basicwidespread

GitHub is an internet platform where programmers store their code, edit it collaboratively, and keep every modification traceable.

In plain terms

Imagine GitHub as a giant shared workshop where every blueprint has every previous version. For public projects, anyone can see who changed what and why, and if something breaks, you can return to an earlier state.

Software is rarely built alone: often dozens or thousands of people work on the same code. GitHub helps them avoid overwriting each other's work. Proposed changes are discussed and reviewed first, and only then merged into the shared version.

It is different from simple cloud storage because it preserves not only files but their entire history and the work surrounding them: bug reports, discussions, and automated checks. A significant portion of the world's open-source software is available here, including many AI tools.

In recent years, not only humans have worked on it. A coding agent can also be assigned a task, write the modification, and submit it for approval, just as a colleague would.

How it works

Code lives in a repository (repo for short): the project folder that contains the files as well as the complete change history.
The developer downloads a copy of the repository to their own machine and works on it there. They save their changes in packages accompanied by brief explanations (commits) and then upload them to GitHub (push).
The new work is done on a separate branch, so the functioning main version remains untouched while development continues.
Once finished, the developer opens a pull request: others review it, add comments, and automated tests run on it.
After approval, the modification is merged into the main version. The AI agent follows the same path when entrusted with a task.

An everyday example

You read an article about a new, free AI program, and at the end it says: "the code is available on GitHub." If you click the link, you see the program's source code, installation instructions, and user bug reports in one place. You can browse it without registration.

Who is affected

developerMost of daily work happens here: code storage, collaboration, review, and increasingly, the management of coding agents. → Code

jobseeker, new graduateA public GitHub profile is, in computing, a kind of portfolio from which an employer can see what and how you worked. → Work & HR

entrepreneur, executiveIf software is being developed for your company, the code is likely here, so it is worth knowing who has access and who owns the account.

parent, student, teacherThose learning programming can find sample projects and teaching materials here, while verified student users can access development tools for free or at a discount. → Education & Family

A common misconception

MythGitHub and Git are the same.

In realityGit is a free version control program usable by anyone, which runs on your own machine. GitHub is a company service built on Git that adds internet hosting and collaboration tools.

Limits and risks

Just because a program is on GitHub does not mean it is secure or reliable: anyone can upload anything, including malicious code.
Public does not mean freely usable: always check the project license, as it defines what you can do with the code.
A common and costly error is accidentally uploading a password or access key to a public repository, from where it can be harvested within minutes.
GitHub is owned by a single company, Microsoft, so an outage or policy change can simultaneously affect countless projects.

Similar, but not the same

Git – Git is the version control software itself, while GitHub is an internet service built on it; Git can be used without GitHub.
GitHub Copilot – Copilot is GitHub's AI-based coding assistant, meaning a product of the platform, not the platform itself.
Cloud Storage – A general cloud storage service stores and shares files, while GitHub manages every change to the code, along with related discussions and reviews.

A brief history

GitHub launched in 2008, built on the Git version control system created by Linus Torvalds in 2005. In 2018, Microsoft acquired it for 7.5 billion dollars. In 2025, its CEO announced their departure, and GitHub was integrated into Microsoft's AI development division (CoreAI).

Where things stand

As of late 2026, GitHub is the world's largest code-sharing platform, with more than 150 million registered users. The emphasis is increasingly on AI: coding agents independently submit changes, which humans approve.
