Score: 7.3/10 (Innovation: 7, Technical: 8, Documentation: 6, Utility: 7)

colm is a Linux terminal workspace manager built on Ghostty, featuring a sidebar, horizontally tiling columns, and a scriptable JSON-RPC control socket. It targets developers running multiple coding agents (like Claude Code) by surfacing permission prompts as actionable cards and enabling remote SSH workspaces.

Target audience: developers and devops engineers running multiple AI coding agents on Linux
