Run Claude Code, Codex and every agent after them side by side on your Mac. See who’s working and who needs you, keep them alive through ⌘Q, let them work as a team — and pick it all up on your iPhone, even on a shaky connection.
// agent-aware
Seedmux recognizes Claude Code, Codex, Grok, OpenCode, Kimi Code, Pi, Antigravity and Devin in any pane and puts their real state on the tab — working, waiting for you, or done. Agents in your other spaces stay in the Agents panel, so nothing finishes unnoticed.
Agents at a glance// dynamic island
Permission prompts and questions appear in the notch the moment they happen — with the agent, the project and the exact command. Allow it right there, or jump straight to the pane. No more prompts buried three splits deep.
Dynamic Island// sessions
Quit, crash or update Seedmux mid-task and your agents keep working. Reopen it and every space, tab, split and scrollback is where you left it — plus whatever they finished while you were away.
Sessions that survive ⌘Q// spaces
Group tabs into spaces with their own colour and folder, swipe between them, and split panes into cards you can drag, tear into tabs and merge back.
Spaces, tabs & splits// agent team
Ask the agent you’re talking to for help and Seedmux opens real worker panes beside it — Codex, Grok, OpenCode, Kimi, Antigravity, Devin or another Claude — hands each one a task, and collects a receipt when the work lands. You watch every worker in its own pane; your agent checks the results and gives you one answer.
How Agent Team works// iPhone
Every session on your Mac and your servers, as a conversation you can read and answer. Approve a command from the queue at the coffee shop, start a new agent from the couch, check your Mac’s screen, open the dev server it just started.
Replies stream in as they are written. Send a message, add one mid-turn, or stop the agent.
Pick a machine, a folder and an agent, type the first message, go.
Watch and control the screen — even unlock it — from the phone.
Tap http://localhost:3000 in a reply and the page opens on the phone.
// weak networks
Walk out the door, step into a lift, ride the subway. The iPhone app moves from Wi-Fi to cellular on its own, is back within seconds, and fills in everything the agent wrote while you were gone. No reconnect button. No lost replies. No duplicates.
// relay
When your phone and your computer aren’t on the same network, a relay passes traffic between them. Seedmux uses the official relay out of the box. Rather keep it on your own server? One command sets one up, one field in Settings points everything at it. Either way it is end-to-end encrypted: the relay forwards, it can’t read.
Run your own relay// and yes
Read any agent session as a conversation, tool calls folded into one line.
Open and edit files next to the terminal. Markdown renders properly.
Panes on Linux servers over SSH — or on machines with no SSH at all.
Jump to any running agent, or resume a recent conversation.
Summon Seedmux from anywhere, send it away again.
Everything in one text file that reloads the moment you save.
Ghostty’s renderer inside a native AppKit shell. No web views.
Fully bilingual, with your choice of CJK font.
