crystl

What crystl is

crystl is a native, Metal-accelerated macOS terminal for multitasking with AI coding agents. Claude Code, Codex and Antigravity CLI are first-class, and any CLI agent runs, including Kimi Code, opencode, aider, goose and Ollama. It also works as a normal terminal.

How it works

• Gems and shards: each project is a gem, each session a shard, all one click away on the rail.
• Isolated shards: a separate git worktree and branch per agent on the same repo.
• Floating cards: approvals, questions and finished tasks surface on screen, color-coded by project.
• Structured terminal: every message, tool call and code change is a metadata-tagged block that other agents can read.
• Agents that operate the app: agents inside crystl get its docs and a CLI, so you can ask them to set up schedules or start other agents.

Features

• Orchestrator agents, crystl quest multi-agent chats and hero shards
• Workbench task list (WORKBENCH.md), project optimizer and agent file editor
• Token tracking, multiple Claude/Codex logins and plan-limit usage
• Scheduling, sequences, dev-server monitor, MCP servers, key store, open models, remote development over SSH
• crystl on iPhone (App Store) to approve and steer agents

Pricing

Apprentice is free with no time limit. Guild costs $170/year and adds orchestration, full agent CLI access, unlimited scheduling, sequence automation, iPhone access from anywhere, formations, 3 devices and priority support.

Who builds it

crystl is built solo by Chris Bolton, founder of the Portland, Oregon consultancy Diviner. Sessions, code and AI conversations stay on your Mac.
