Superagent
A home for your agent.
エージェントの帰る場所。
Your coding agent, with a browser of its own, an iPhone on the desk, and you in your pocket.
- Works with
- Claude Code
- Codex
- Antigravity
Free. Open source. On the plan you already have.
Your agent can already write the code. Superagent gives it what a developer has: a browser, a phone to test on, a desk. And it gives you a seat to watch from.
- Runs on your Mac
- No account
- Open source
Every agentすべてのエージェント
Claude, Codex, Gemini. Never stuck.
Pick Claude Code, Codex or Antigravity (Gemini) for each chat. When an account runs out, Superagent moves the chat to your next one and keeps going.
Add more than one account per agent, and turn on Automatic under Settings → Agents → When an account hits its limit; otherwise the chat asks first, with a button to switch. If only one Claude model runs out (Fable’s weekly limit, say), the chat steps down to the next model and goes back once it can. A chat never changes agent on its own; you pick that.
Browserブラウザ
You ask. It builds. You watch.
Your site opens next to the chat, in a real browser the agent clicks through itself. No more “does it work?”
Filmed in the app: the agent signs up on the page, checks it at phone size and reports back.
The sidebarサイドバー
Every task gets its own chat.
Spinning while it works. A dot when it’s done. Nothing to babysit.
Chats survive restarts and remember their own work. Projects wear their real icons: the site’s favicon, or your app’s icon from Xcode.
Worktree chats各チャット、各ブランチ
Try anything. Break nothing.
A chat can work on its own branch, in its own copy of your project. Like what it made? Keep it. If not, throw it away.
Under the hood it’s a git worktree named after the chat. Your folder doesn’t change until you press Keep, and then it lands as one change.
The simulatorシミュレーター
An iPhone, right in the window.
The agent boots the Simulator, taps through your app and tells you what broke.
It uses the Simulator that comes with Xcode. Nothing else to install.
Desktop & phone at once二重表示
Desktop and phone. At once.
One page at two sizes, side by side, both live. Fix it once, see it twice.
One session behind both, so a sign-in counts for both. The agent switches between phone, desktop or both on its own.
Split view分割表示Beta
Eight agents. One window.
Chats from any project, side by side, all working at once.
⌘-click a chat, or drag one in from the sidebar or ⌘K. Resize, rearrange, or give one the whole screen. Splits are saved in the sidebar, and ⌘1–8 jumps between windows. Up to eight on the Mac, four on iPad. In the 2.1 beta.
Browser automation自動操作
It does the clicking.
On the sites you’re signed in to, it reads, fills in, clicks and sends. Like you would, minus the tedium.
It works in its own tab, so yours stays yours. Stop it whenever you like.
Snip切り取り
Show it. Don’t describe it.
Drag a box over the page or the phone screen, and the crop lands in your message.
Works on the browser and on the simulator, with ⌘⇧S or the scissors button. It never steals your focus.
Notifications通知
It knocks. It never barges in.
Finished, or needs your yes? You get a notification. Whatever you’re doing stays in front.
A normal macOS notification with the gist of the reply. Click it to jump straight to that chat.
Lid closed蓋を閉じても
Close the lid. It carries on.
Turn it on once, and a long job finishes while your MacBook is in your bag.
Off by default. macOS asks for your password once, and while Superagent is open your Mac will not sleep, so it stays awake, and warm, in a bag. On battery you pick the level under which it is let sleep (20% unless you change it). Settings, General, Power.
iPhone and iPad電話
Your agent, in your pocket.
Follow every chat, approve what it asks, hand it the next job. From the sofa, the train, anywhere.
Pair once with a QR code. Messages are encrypted end to end and pass through a relay that can’t read them; you can run your own. The same sidebar and pins as on your Mac, and you can switch between Macs. Live while the app is open, a notification when it isn’t. iPhone and iPad · iOS 26 · Free and open source.
Routinesルーティン
Set it and forget it.
Say “do this every morning”, or add a job in View › Routines. Then it just happens.
Routines run while Superagent is open.
The boardボード
A board the agent keeps.
Todo, Doing, Testing, Done, for each project. Watch the cards move while it works.
Add a card yourself or ask the agent to. Click a card to hand it over, and the agent starts on it. Your phone shows the same board.
Skillsスキル
Teach it once.
Skills and commands from your project and your own setup, in one list. Save what worked as a new one.
Open it from View, Skills, or from ⌘K. It shows the skills and commands the chat’s agent can run, marked project or global. Saving asks the agent to write the skill file for you: Claude Code skills, Codex prompts or Antigravity skills.
The dot点Beta
Ask from any app.
Press ⌥ Space. It sees what you see, then answers or does it.
Nothing is recorded in the background. The answer appears by the dot, and the chat is saved for later. Turn it on in Settings › General.
Computer useコンピューター操作Beta
It can use your Mac. If you say so.
It asks first, then again for every app. ⌥ Esc stops it instantly.
Off until you say yes. Password managers, Keychain and the lock screen are always off limits.
The Computer机
A desk for your agents.
A desktop inside Superagent, with windows, a dock and room for several agents at once.
Chat, browser, dashboard, skills, routines and calendar, each in its own window. Everything your agents are up to, on one screen.
Who it’s for誰のために
See the work. Not the code.
The page, the app and the phone sit right next to the chat, so anyone can tell whether it’s right.

Open & localオープン・ローカル
Don’t trust us. Read us.
An agent with your logins should have nothing to hide. Every line of Superagent is public.
Open source.
The Mac app, the iPhone app and the relay, MIT licensed.
No server of ours.
Chats, code and pages stay on your Mac.
No account.
No sign-up, no tracking, no second bill.
Signed and notarized by Apple: the app you download is the build that was published. Bugs and plans are discussed in public. Claude Code talks to Anthropic, Codex to OpenAI, Antigravity to Google, directly, on your own subscription. Browser sessions are stored on your Mac, like any browser’s. Only when you pair a phone does the Mac use a relay, and it sees nothing but encrypted data; you can run your own with one command.
Read the code for the Mac app, the iPhone app and the relay, or see all three in one place.

Pricing料金
Free forever.
Really.
No plan, no trial, no card. Your agent runs on the Claude, ChatGPT or Google plan you already have.
What’s the catch? You already pay for the AI. Superagent just gives it a home.
Questionsよくある質問
Good questions.
Is Superagent a GUI for Claude Code?
Yes. It runs the real Claude Code CLI on your Mac and gives it a window: chats per project, a built-in browser, an iOS Simulator and an iPhone app. It does the same for OpenAI Codex and Google Antigravity, and you can switch agent per chat.
Do I need an API key?
No. It uses the agent you are already signed in to, on your Claude Pro or Max, ChatGPT Plus or Pro, or Google AI plan.
Is Superagent free?
Yes, free forever. No plan, no trial, no card, no account. It is open source under the MIT license.
What’s the catch?
There isn’t one. You already pay for the AI: Superagent runs on your own Claude, ChatGPT or Google plan, so there are no tokens of ours to bill you for. It has no servers of ours either; everything runs on your Mac, and the small encrypted relay for the phone costs next to nothing and you can host your own. It is open source under the MIT license, with no account, no tracking and no ads. All it needs is a Mac with Apple Silicon and a plan for at least one of the agents.
What happens when I hit my Claude limit?
Superagent moves the chat to your next Claude account that still has allowance, and the conversation carries on where it was. With Automatic on (Settings, Agents, When an account hits its limit) it switches by itself and says so; otherwise a card asks first, with a button to switch. If only one model's limit runs out, such as Fable's weekly limit, the chat steps down to the next model and goes back once it can. It never moves a chat from Claude to Codex or Antigravity on its own; you choose the agent per chat.
Can I run several Claude Code or Codex sessions at once?
Yes. Each chat can work in its own git worktree on its own branch, so parallel agents don't step on each other, and split view shows up to eight chats in one window.
Can the agent test my website in a browser?
Yes. It drives a real browser next to the chat: it opens pages, clicks, types, takes screenshots and checks the page at phone size, on the sites you are already signed in to.
Can I use it from my iPhone or iPad?
Yes. The iPhone and iPad app follows your chats, end-to-end encrypted, so you can answer the agent and approve what it asks from anywhere.
Does my code leave my Mac?
No. Everything runs locally. The only traffic is your agent's own connection to its provider, update checks, and an encrypted relay if you pair a phone.
Does Superagent support Claude Code skills?
Yes. Open Skills from the View menu or ⌘K to see the skills and commands the chat’s agent can run, marked project or global. “Save last session as a skill” asks the agent to write the file for you: a Claude Code skill, a Codex prompt or an Antigravity skill. With none yet, it offers starter skills.
Can I send part of the screen to the agent?
Yes. Press ⌘⇧S, or the scissors on the browser or the simulator, and drag a box over the page or the phone screen. The crop lands in your message at full resolution.
Can the agent read and send my email?
Yes, once you connect Apple Mail in Settings, Connections. The agent can then search and read your mail and write drafts. It sends nothing by itself: each email is shown to you first, with its recipients, subject and attachments, and goes only when you approve it. macOS asks for permission the first time.
Can the agent keep working with my MacBook lid closed?
Yes. Turn on “Keep working with the lid closed” in Settings, General, Power. It is off by default, macOS asks for your password once, and your Mac stays awake while Superagent is open. On battery you choose the level under which it is let sleep, 20% unless you change it.
Does it work on Windows or Linux?
Not yet. Superagent is a Mac app for Apple Silicon.
