エージェントの帰る場所。

A Mac app where your coding agent lives: a real browser it drives, an iPhone in the window, chats that survive restarts, your phone in the loop. Open source, on the subscription you already have.

One chat per task. Each one keeps its own context and picks up mid‑thought. A spinner means it is still going. A dot means it finished without you.

`docs/index.html`

— the sub is one line now.`Landing: shorter hero sub`

.`/login`

but read on `/`

, so the guard bounced you every time.`path=/`

and added a regression test.`tests/auth.spec.ts`

asserts the cookie is cleared on sign‑out.`pnpm-lock.yaml`

replaces `package-lock.json`

; CI is green on the branch.`eslint-config-next`

. Pinned them in `.npmrc`

and the install is clean.Click a session. The whole conversation is already there.

Start a chat on its own git worktree and it commits somewhere else entirely. Your checkout does not move. Not one file.

`superagent/fix-auth`

. Commits land there; `main`

stays where you left it.Commits land on the branch. Main stays put.

A real iOS Simulator, streamed from its own framebuffer. It taps. It types. It swipes. Nothing to install.

You ask once. It boots the device and reports back.

The same page as a desktop card and as a phone. One session, both live. Change something and it lands in both.

Two screens. One truth.

Say what you want done. It opens the site you are already signed in to and works it the way you would — reading, writing, clicking, sending.

You ask once. It does the rest, in your own browser.

Your window stays exactly where it is. When the agent finishes, or needs a yes, it says so from the corner.

`git push --force-with-lease`

It waits in the corner until you are ready.

Pair the iPhone app once and it follows your Mac from anywhere: the conversation as it happens, a prompt from the sofa, a yes or no when the agent asks. End-to-end encrypted, through a relay that can't read a word of it.

iPhone and iPad · iOS 26 · free, and open source like the rest

`git push`

?Live while it's open. A push when it isn't. Nothing in between can read it.

A desktop, not a slot. Windows you can move, a dock, and more than one agent working at the same time.

Everything it is doing, on one surface, at the same time.

コードは、二番目。

Every tool in this category is built for the same person: someone who reads diffs for a
living. Superagent is built the other way round — for **the person who
doesn’t write code first, and the person who does second.** Not by hiding the
code, but by putting the page, the app and the phone on screen next to the chat, so you
can judge the work the way you judge anything else: by looking at it.

Checked against each product’s own docs, August 2026. [Tell us if any of it is wrong.](https://github.com/pungme/superagent-desktop/issues)

**You describe a thing, and watch it get built** — on your own machine, on your
own accounts, on the subscription you already have. No terminal to learn. No sandbox to
escape.

An agent with a browser is an agent with your logins. Don't take our word for what it does with them — every line of code is public, so you can read it, build it yourself, and check.

Not a wrapper with a peek at the source. The desktop app, the iPhone app and the relay are all on GitHub under MIT — every line.

There is no Superagent server. There is nowhere for your work to go but your own disk — and you don't have to believe that either: it's in the code.

Don't trust, verify — the [desktop app](https://github.com/pungme/superagent-desktop), the [iPhone app](https://github.com/pungme/superagent-ios) and the [relay](https://github.com/pungme/superagent-relay). [All three in one place](https://github.com/pungme?tab=repositories&q=superagent).

**Install.** Point it at something. **Talk.** Then watch it work in the pane next door.
