iOS Simulators, as an API.

For AI app builders, agent companies and QA platforms.

Medians from the US east coast. A project's first build takes longer.
The whole integration
import { NoMacSimulator } from "@nomac/simulator";
const nomac = new NoMacSimulator();
// A Simulator for your user, booted in seconds
const phone = await nomac.phones.start({ label: user.id, reuse: true });
await phone.waitUntilReady();
// Their app, built with Xcode beside it (the token is never stored)
const { root } = await phone.fetchGit({ url: user.repo, token: user.gitToken });
await phone.tool("app_run", { path: root });
// The live screen for your page: <NomacPhone url={url} />
const { url } = await phone.viewLink({ control: true });Start a Simulator, build the app, show the screen.
Made for platforms
One Simulator per user
Your user's id is the label: their project, build cache and saved states come back with them, private to them.
In your page
One React component, or a link with no sign-in to watch or control. Your user and your agent share one screen.
The screen as text
Your agent reads the screen as text and taps by label. A sign-in screen is about 70 tokens, not a screenshot.
Native builds in seconds
Xcode 27.1 builds Swift and Xcode projects on the same Mac, so a change is on screen in about 7 seconds.
Secrets never stored
A git token travels with the call that uses it. One call deletes everything a user left behind.
Usage per user
Each session ends with a signed webhook: your user's id, the minutes and the cost, to bill your way.

Talk to usQuestions
Who is it for?+
Products whose users need iOS of their own: AI app builders that show the app as it is built, agent companies whose agents test iOS apps, and QA platforms.
How many Simulators at once?+
Every account runs 2 at once, enough to build and try it. NoMac Enterprise raises your account's limit, with reserved capacity if you need Simulators nobody else can take.
What does NoMac keep about my users?+
Per user: their workspace (project and build cache) until it is 90 days unused, saved states until you delete them, and each session's replay for 7 days. Never their secrets. One call deletes it all; the sessions' times and cost stay for billing.
Which languages?+
TypeScript and Python SDKs, and a REST API for anything else. The live screen is one React component, or one function for any page.
