Nyx is a modern terminal for Mac that natively supports AI coding agents. Key capabilities include multi-agent orchestration (delegation, instruction sending, result reading), side-by-side browser with NYX MCP for live app testing, flexible workspace organization with tabs and split panes, shell integration for zsh/bash/fish, regex scrollback search, command palette, and asciicast session recording. Agents can create panes, send terminal input, and coordinate across workspaces while maintaining clear access boundaries.
