I built Neptune partly because I couldn’t find a terminal I liked for working with AI agents. cmux didn’t run well on my Ubuntu setup, and Ghostty was missing some features I liked in cmux. I wanted something free and open source that works well across Linux, macOS and Windows. It’s still early, so I’d like to hear how it works for you and what needs improving.
