NestMux

What is NestMux?

NestMux is a desktop terminal workspace for developers who run several AI coding agents at once. Instead of switching between tabs, you tile Claude, Gemini, Codex, Copilot, OpenCode and custom CLIs in one grid of panes, each with its own process, home directory and account. Native git worktrees give every branch its own dependencies, dev server and agent, a built-in diff viewer opens changes in your editor, and GitHub and GitLab are connected through OAuth for pull requests, issues, CI runs and AI code review. A visual panel manages Model Context Protocol servers without hand-editing settings files, and a Chromium cell previews your dev server beside the agent. Teams get shared terminals through a short join code, chat, shared snippets and an activity feed. NestMux runs on macOS, Windows and Linux. The Free plan allows up to 3 panes, Pro costs $15/mo and Team $26/mo, and the site says plans are free during launch.

Use cases

Why use NestMux

• Agents from different vendors share one window, so you stop juggling tabs and logins.
• Worktrees keep each branch's dependencies, dev server and agent separate, so parallel tasks do not collide.
• Pull requests, CI runs and code review live in the same workspace as the agents that write the code.
• Shared snippets, MCP configs and terminal sharing let teammates reuse the prompts and setups that work.
• Local-first design with a free tier makes it simple to try on a personal project.

5. Invite teammates with a join code to share terminals, snippets and the activity feed.
