colm is an open-source Linux workspace manager for coding agents built on Ghostty, featuring a sidebar for managing workspaces, horizontal column tiling like niri, live terminal thumbnails, and a JSON-RPC socket for scripting. It integrates with AI agents like Claude Code to surface permission prompts and activity in a feed sidebar, with support for remote workspaces over SSH.
A developer describes their terminal-native setup for running multiple coding agents in parallel, combining Ghostty terminal, Git worktrees, and Herdr multiplexer to manage isolated agent workspaces while maintaining remote access via iPhone.
