Tmux-IDE: Open-Source Agent-First Terminal IDE for Claude Teams

Tmux-IDE is a new open-source tool that turns any project into a tmux-powered terminal IDE optimized for AI agent workflows. It provides native support for Claude Code agent teams, letting a lead agent coordinate multiple Claude instances working in parallel across a codebase.

With a single ide.yml config file, developers can define multi-pane tmux layouts with dev servers, agent panes, and custom startup commands. The tool auto-detects project stacks (Next.js, Vite, Python, Go) and configures environments accordingly. Because it runs over tmux and SSH, developers can start agents remotely and disconnect while they continue working.

Key features include declarative YAML configuration, per-pane working directories and environment variables, theme customization, and JSON output for programmatic integration. The CLI supports launch, init, stop, restart, validate, and inspect commands. It also works with Gemini and Codex alongside Claude.

This addresses a real pain point: orchestrating multiple AI coding agents in terminal sessions has been cumbersome. Tmux-IDE provides the missing layer between tmux and agent teams.
