crystl

Most AI coding tools assume you run one agent at a time. crystl assumes you run six, and that's a different problem. The git-worktree isolation alone saves you from merge hell when several Claude Code sessions touch the same repo—each shard works in its own branch. Floating action panels are another win: approvals and questions pop up as glass panels instead of burying you in scrollback. If you've ever missed an agent waiting on input, you'll feel the difference. Where it gets interesting is orchestration. The Guild tier lets you anoint an orchestrator to manage subagents, and crystl quest turns agents into a role-played party that divides work and reports back. It sounds gimmicky, but in practice it makes multi-agent workflows legible. The CAVRN engine's structured metadata means agents can read each other's sessions, which is subtle and powerful—your orchestrator actually knows what its workers did. When should you pass? If you're on Windows or Linux, stop here. crystl is macOS-only. If you run one agent occasionally, the learning curve and terminal depth are overkill. And if you rely heavily on Antigravity CLI, note it lacks hook support for action panels, so you lose some of the magic. Also, the free tier limits scheduling to 3 agents and offers read-only CLI—fine for trial, but heavy users will feel the ceiling. Compared to alternatives like a plain tmux setup or a generic terminal, crystl is a different animal. tmux gives you tabs; crystl gives you awareness—it tracks tokens, shows which agents are blocked, and lets you search past sessions. There's nothing else this focused on multi-agent supervision. The caveat: it's a young tool with a fast changelog (2.186.1 landed August 2026), so expect occasional rough edges, but the team is actively fixing rendering
