GitHub is a web-based service for hosting and managing software development projects, primarily used by developers and teams. It provides a central place to store code, track changes, and coordinate work.

Version Control: The core system tracks every change made to a project's files, allowing teams to revert mistakes, compare versions, and understand the history of their code. Collaboration Tools: Features like issue tracking, pull requests, and code review workflows facilitate discussion and coordination among contributors on a project. Project Hosting: It serves as a public or private repository for source code, documentation, and other project assets, making them accessible to team members or the wider community. Integration Ecosystem: It connects with a wide array of development, testing, and deployment tools, allowing teams to automate parts of their workflow. Community and Discovery: Users can explore millions of public projects, fork them to create their own versions, and contribute improvements back to the original.
