Compatible with Eclipse and IntelliJ IDEA, it enables multiple developers to work concurrently on shared projects, with each participant maintaining a local copy of the project synchronized in real time. Key features include support for multiple concurrent writers, a follow-mode to observe team members' navigation and editing activities, and awareness information displaying recent contributions and current selections of all participants. Saros supports sessions with up to five participants and allows users to host their own servers to keep all communication within their network. This design enhances collaborative coding experiences, making it suitable for scenarios such as pair programming, code reviews, and mentoring.
