Crystl is a macOS terminal built for Claude Code, enabling users to organize projects and run parallel sessions seamlessly.
I created Crystl because I needed a better way to manage Claude Code projects. As a technical marketer, I often run Claude across half a dozen projects in a single day. Keeping track of terminal windows, sessions, monitoring progress, and constantly switching between apps and browser tabs was becoming overwhelming. I tried several terminal tools. Some I really liked — but none helped me conduct the orchestra of agents the way I imagined. With Crystl, I can run many agents across many projects while always knowing which are carrying the tune and which are patiently waiting for a wave of my baton. Crystl is a macOS terminal built specifically for Claude Code and multi-agent orchestration. It also supports other AI agents (though not as deeply as Claude), and functions as a normal terminal. Crystl organizes projects into gems, manages terminal sessions as shards, and handles permission approvals through floating glass panels without hunting for tabs or windows.
