The platform is GitHub, an online service for hosting code and collaborating with others. It uses version control technology called Git, which allows for incremental changes (commits) and branching for separate work on parts of a project. GitHub combines this with a software-as-a-service model, making it one of the most-used platforms for collaborative development projects. The platform is free to use, with some paid plans offering additional features such as unlimited collaborators and advanced tracking tools. It provides tools for searching, contributing, managing repositories, pull requests, issues, and releases, as well as integration with other apps and services via Zapier. GitHub also offers a user-friendly interface for developers who are not pros at Git or version control, while still catering to seasoned developers. The platform has become a crucial part of the developer job market, allowing users to showcase their contributions and work on open-source projects.
