Lumen for Mac, iPhone and iPad
Every agent, one window.
Lumen runs Claude Code, Codex, Cursor, Antigravity, OpenCode and Muse side by side on your Mac and iPhone. When one needs you, it asks in one place, and they keep going when you quit.
Split work
One thread split the work.
Two agents took a half each and finished side by side. You watched, and stepped in once.
Shimmer the status island
Codex
Give the status island a shimmer and a live elapsed timer.

+29 - Ran the build

The six agents
Six agents in one sidebar.
Lumen tools let an agent split a task with another agent, ask a second thread and wait for its answer, or move its own thread into a project.
| Agent | Made by | Asks you | Lumen tools |
|---|---|---|---|
| Claude Code | Anthropic | In a picker | All |
| Codex | OpenAI | In a picker | All |
| Cursor | Anysphere | In its reply | None yet |
| Antigravity | In its reply | None yet | |
| OpenCode | SST | In a picker | On the Mac |
| Muse | Meta | In a picker | On the Mac |
Each thread
Set up each thread.
Pick the agent, its effort and its access in the composer. Type the task and press Return. It starts at once on your Mac or your server.
Pick the agent
Each runs its own official command-line tool, signed in as you. Lumen starts it, reads it and shows it the same way.
Choose how hard it thinks
Effort goes with the thread, from low to max. A quick rename needs less thinking than a migration.
Decide what it may touch
Plan only reads. Auto-edit edits files and asks before commands. Auto asks before anything risky. Full access asks nothing.
Give it a worktree
Its own branch and folder, so two agents can work on one repo at once. Merge when you're happy.
What they can do
Tools from Lumen.
Lumen gives its agents nearly fifty tools of its own. Claude Code and Codex get them on your Mac and on your servers; OpenCode and Muse for projects on your Mac. Cursor and Antigravity don't get them yet.
Other agents
Start one on part of the task, wait for it, message it and merge its work.
Your threads
Read and search them, fork one, or ask one a question and get its answer.
Projects and machines
Find a folder on your Mac or a server, make it a project, move a thread there.
Schedules and webhooks
Run a prompt at a set time, or when something calls a webhook.
Pull requests
Link a thread's pull requests, watch them and list them.
The preview browser
Open your dev server beside the thread, click, type and take snapshots.
The Simulator
Boot an iOS simulator, open a link, launch an app and take a screenshot.
Questions and secrets
Ask you with a picker, or ask for an API key without it passing through the chat.
After you quit
Quit, and they continue.
Lumen stays in the menu bar until every agent finishes. The work waits in your Inbox.
Lumi
Lumi is always on.
An agent that lives on your Mac and your server. Mention @lumenbynnx on GitHub, message it on Discord, Telegram or Slack, or ask it in Lumen. Each request is a job on its own branch, and it asks you before it merges.
Composer crashes when the iPad rotates #41 · Open
you commented: @lumenbynnx can you fix this?
lumenbynnx[bot] replied 4 minutes later: The toolbar's width went negative halfway through the rotation. I fixed it on lumi/ipad-rotation and opened #42. I'll ask you in Lumen before it's merged.
Mac first
It answers on your Mac while it's awake. Your server takes over when it sleeps.
Jobs you can follow
Tap a job to see each command it ran, file it changed and tool it used, and how long each took.
Schedules and webhooks
Jobs that start at a time of day, or when a signed webhook is called.
Memory you can edit
Say "remember…" and it does. Change an entry, or swipe to forget it.
Spending limits
A daily budget, a limit per job, and a word from Lumi before a costly one.
Pull requests it watches
It answers review comments and fixes failing checks, then asks before merging.
Guests stay guests
Collaborators get answers, never your memory or your logins.
Your Lumen Account
Sign in with GitHub once. It reaches your Mac and servers from anywhere, and tells Lumi it's you.
Servers
Your own server.
Run agents on a Linux box, a Windows PC or a spare Mac that stays on. They keep going when your Mac sleeps, and your iPhone and iPad follow them too. The server connects out to the relay, so it needs no open ports, and every way in is end-to-end encrypted. Lumen Server is signed, and you can update it from Lumen.
Linux and macOS
Starts at boot, then shows a QR code and a pairing code
curl -fsSL https://lumen.nnx.fyi/server | shWindows
In PowerShell · starts when you sign in
irm https://lumen.nnx.fyi/server.ps1 | iexInstall
Run the line on the machine. It needs Python 3.9 or later and never asks for admin rights.
Pair
In Lumen, Settings → Servers → Add Server…, then scan the QR code or type the code.
Sign in there
Install your agents on the server and sign in to them there.
Add a project
Add from a Server… picks a folder on it. Git works there as it does on your Mac.
iPhone and iPad
On iPhone and iPad.
Pair once with your Mac, then follow and answer every agent from anywhere. Everything between them is end-to-end encrypted.
Three columns on iPad
Your threads, the thread, and its inspector, side chat or sub-agents beside it.
Live Activities
Running agents on the Lock Screen and in the Dynamic Island, with Approve and Deny right there.
Answer from a notification
Approve, deny, reply, or stop a long run without opening Lumen.
Mark up with Apple Pencil
Draw on a picture an agent showed you, add a note, and send it back.
Dictate a whole task
Tap the microphone and talk. The words appear in the composer as you go.
Replies read aloud
Hear the answer when a turn you're watching finishes.
Live links
Share it live.
Choose Share Live Link in a thread's menu on the Mac. Anyone with the link watches the thread in a browser as the agent works, read-only. The key lives only in the link, so the relay passes on scrambled bytes. Allow suggestions and they can propose a message; it reaches the agent only if you approve it.
