GitHub

Host Git repositories and enable massive-scale collaboration (pull requests, issue tracking) for over 100 million developers.

GitHub is the world's dominant web-based platform for Git repository hosting and collaborative software development. Built on Linus Torvalds' Git version control system, the platform facilitates 'social coding' by providing essential tools like pull requests, forking, and issue tracking. It currently serves over 100 million developers, managing a massive ecosystem of public and private codebases. Microsoft acquired the company in 2018 for $7.5 billion, solidifying its role as the central hub for open-source and enterprise-level version control.
