CoVim enables collaborative, real-time editing sessions in Vim by networking multiple clients into a shared buffer. Participants can see each other’s cursors and changes as they type, approximating pair programming inside a modal editor. Sessions are hosted on a server process that coordinates edits and user presence across machines. The goal is to keep collaboration simple while preserving familiar Vim motions and commands. It is particularly handy for remote code walkthroughs, mentoring, or quick review sessions without switching to a different editor. While not as full-featured as cloud IDEs, it provides a lightweight way to co-edit in pure Vim.
