Best for

Solo developers and small ops teams who already drive Claude Code, Codex, or Gemini CLIs on remote servers and want a first-class iOS interface to babysit and steer those agents from a phone or iPad.

Skip if

Android users, teams that need a shared web dashboard, and anyone expecting a hosted agent service — Agentmux is a mobile front-end, not a model provider.

Agentmux is an iOS app that turns an iPhone or iPad into a mobile command center for remote development work driven by AI coding agents. It wraps SSH, tmux, and one-tap launchers for Claude Code, Codex, Gemini, and OpenCode into a touch-friendly interface, so developers can supervise long-running agent sessions from the couch, a commute, or a phone in bed without rebuilding shell context every time the connection drops. Because it leans on tmux for persistence, an agent kicked off on a server keeps running when the iPhone sleeps or the network switches from Wi-Fi to LTE, and reattaches cleanly on the next open. The app pairs the terminal with a remote file browser that renders syntax-highlighted code, plus (on the Pro tier) a remote code editor that saves over SSH, a workspace concept for juggling multiple servers, and utilities for file history, branch switching, and batch operations. It is not a hosted agent service — Agentmux does not run models itself. Instead it assumes you already have accounts and CLIs for the agent providers installed on your dev boxes, and it acts as a well-designed mobile front-end and session manager on top of them. The typical workflow is: SSH into your VPS or workstation from the app, launch a Claude or Codex session in a named tmux window, watch it work, jump into a sibling shell to inspect diffs or run tests, and edit the odd file directly from the phone before detaching. A 14-day full-feature trial makes it low-risk to see whether phone-first agent supervision fits your rhythm.

Editor's take

A refreshingly focused product: instead of another hosted agent platform, Agentmux accepts that most serious developers already have Claude Code or Codex on a VPS and just need a decent way to check on them from a phone. The tmux persistence layer is the right architectural bet, and the free tier is generous enough to actually validate the workflow before paying.

Pros

✅ One-tap launch for Claude, Codex, Gemini, and OpenCode CLIs alongside a normal shell
✅ tmux-backed persistence survives network changes, sleep, and Wi-Fi-to-LTE handoffs
✅ Touch-friendly terminal UI purpose-built for iPhone and iPad rather than a generic SSH client
✅ Remote file browser with syntax highlighting for quick code review from mobile
✅ Pro tier adds a remote SSH editor, multi-server workspaces, and branch/file history tools
✅ Free tier is genuinely usable for single-server work, not just a demo
✅ 14-day full-feature trial exposes every Pro feature before committing

Cons

⚠️ iOS-only — no Android, macOS, or web client
⚠️ Does not run its own models; you must bring and configure the underlying agent CLIs on your own servers
⚠️ Pro pricing is not clearly published on the marketing site, making budgeting harder
⚠️ Small independent app with limited public track record versus established mobile SSH clients
⚠️ Typing serious code on a phone remains awkward regardless of UI polish, limiting deep sessions
⚠️ No documented public API or open-source code for extension or auditing
