GitHub

GitHub is the platform where most of the world's open source code lives, and also the versioning and collaboration system adopted by almost every professional development team. Acquired by Microsoft in 2018, it now hosts over 420 million repositories.

GitHub is a hosting platform for Git repositories that adds a complete collaboration and automation layer on top of code versioning. At the center is the repository: a space where code is stored with its entire history of changes. The pull request system lets collaborators propose changes that are discussed, reviewed and then integrated into the main code. Issues track bugs, feature requests and discussions; Projects organize work in kanbans and roadmaps. GitHub Actions is the integrated CI/CD system that automates build, testing and deployment when defined events occur. GitHub Copilot, the AI code-writing assistant, has become one of the most widely used tools in the sector and is available as an add-on. GitHub Pages lets you publish static sites directly from a repository. The platform is also the meeting point of the global open source community: forks, stars, watching and contributions are the social language of modern software development.

For developers, development teams, organizations and open source contributors who want to manage code, collaborate and automate development processes on a reliable and universally adopted platform.

GitHub is free for public and private repositories for individual users, with basic collaboration features included. The Team plan costs $4 per user per month (billed annually, $4.50 monthly) and adds wikis, protected environments, required reviewers and other team tools; the Enterprise plan costs $21 per user per month with advanced security management, compliance and deployment. GitHub Copilot, the AI assistant, is a separate add-on at $10 per month for individual use ($19 for companies). Open source organizations and academic institutions have free access to many advanced features.
