I'm thrilled to release CodeAlta - one of the first efficient AI coding-agent TUIs built entirely in C#/.NET 🚀 I've been developing and using it daily for the past 3 months, and I hope you enjoy it as much as I do! 🤗 Retweets are highly appreciated! 🙏 CodeAlta brings you a beautiful, colorful timeline interface, multiple threads in the same workspace, a real prompt editor experience, quick file viewing/editing with syntax highlighting, in-app model provider configuration, a multi-agent-ready environment, and much more! ✨
