About crystl

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.

What it is

crystl is a macOS terminal built for multi-agent orchestration. Claude Code, Codex, and Antigravity CLI are first-class agents — any CLI agent runs — and it functions as a normal terminal too. crystl organizes projects into gems, manages terminal sessions as shards, and handles permission approvals through floating glass panels without hunting for tabs or windows. When you need to run multiple agents on the same repo, the isolated shards feature creates git worktrees so each agent gets its own branch, no conflicts.

crystl Quest lets you build agent teams with their own skills. They talk to you and to each other, so they get work done faster and with fewer mistakes.

With crystl, every conversation is preserved. You can come back hours or days later and see exactly what was accomplished, what was approved, and the context of each session.
