About crystl

I created crystl because I needed a better way to manage AI coding agents. As an agency owner, I often run agents across half a dozen projects in a single day — and working in parallel left me with a confusing pile of windows and tabs, each stuck at some unknown stage of progress. Keeping them all on task meant constantly hopping between sessions just to find out who was waiting on me.

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 Metal-accelerated macOS terminal built for multitasking with AI agents. It's like an operating system for your projects. crystl is accessible for beginners and a power tool for advanced workflows. Everything printed to the terminal in crystl is a block with unique metadata. Every message, tool call, and code change is tracked and tagged, so your agents can see what's happening in real time. It also makes them time and date aware.

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.
