Mux is a desktop & browser application for parallel agentic development. It enables developers to plan and execute tasks with multiple AI agents on local or remote compute.

sonnet-4-*, grok-*, gpt-5-*, opus-4-*)Mux has a custom agent loop but much of the core UX is inspired by Claude Code. You'll find familiar features like Plan/Exec mode, vim inputs, /compact and new ones
like opportunistic compaction and mode prompts.
