MobAI gives AI agents eyes and hands for mobile apps.
They can control iOS and Android apps on simulators, emulators, and physical devices, then verify the result instead of guessing from code.
Build the app. Let the agent test it. Fix what it finds.

It's way more fun to build for decision models than LLMs.
LLMs can work around rough edges in your tooling. Jev makes you fix them. And that's actually the part I enjoy most.
Been having a lot of fun with mobile E2E testing in MobAI lately.
Btw, you can try it locally or in CI: mobai.run/ci
Just released @mobai-app/e2e, a new mobile engine for the @TesterArmy e2e.
Run iOS and Android E2E tests with:
- Real devices on macOS, Linux & Windows
- Simulators, emulators & device farms
- Hold devices on failure in CI for inspection
- MobAI testing dashboard integration

Codex Cloud supports Tailscale now.
Sandbox joins the tailnet. Dashboard says "Connected."
TCP proxy refuses connections. HTTP proxy returns 200 OK for nonexistent addresses.
Connected to everything. Reaches nothing 👍
For iOS devs, this is possible too.
With MobAI, coding agents run on Linux while still being able to build iOS apps, preview UI changes, run remote simulators, and test on real iPhones. All of this from the cloud.

Now that AI agents can develop iOS apps from their default cloud sandboxes, the next problem to solve is the feedback loop.
How does cloud agent actually see and test what it's building?
I've been working on this in mobai-dev, with three levels of feedback 🧵
I don’t need a spare Mac mini to build iOS apps from my phone anymore.
Cursor and Claude cloud agents can build, test, and ship entire iOS apps from Linux sandboxes already included in my subscriptions.

3️⃣ Your own iPhone
With Tailscale, the cloud agent can install apps, see the screen, and control your phone remotely.
Wi-Fi is needed to start the session, but after that, it works over cellular too.
mobai.run/docs/cloud-agents/…
From UI previews to CI simulators to real devices, all from a Linux sandbox.
No need for a spare Mac anymore.

E2E mobile testing in 2026:
Open Numbra
Go through onboarding
Check we’re on the paywall
Skip it
Check the main screen shows a welcome message
This is the actual test, not a prompt. Jev, Clef, and now OpenAI’s Luna run it locally and in CI.

simslim 0.12 is out!
It now slims Apple Watch, Apple TV, and Apple Vision Pro simulators, not just iPhones.
brew upgrade simslim

Spent some time rebuilding the MobAI landing page.
I think it finally explains the idea properly. Give your coding agent the whole mobile dev loop, from running the app and checking changes to e2e tests and CI. Even from Linux cloud agents.
mobai.run
Very cool.
There’s also a less adventurous way to do iOS development from Linux/Windows 😄
ios-builder uses real Xcode on ephemeral CI, while you stay entirely on your PC. Build, sign, install on your iPhone, and ship to TestFlight/App Store.

Apple says you need a Mac to build iPhone apps.
Today I built one on Omarchy Linux, submitted it to the App Store, installed it on my iPhone over USB, and stopped it at a breakpoint in the debugger.
No Mac anywhere.
It's all open source:
github.com/joshuaswarren/oma…
Get your app ready with your agent and MobAI.

Apple Announces iPhone Duo Apps Can Now Be Submitted to App Store macrumors.com/2026/10/05/app…
ios-builder just hit 1,000 GitHub stars 🎉
It gives you one CLI to build, sign and ship iOS apps from pretty much anywhere, whether you use Swift, React Native, Flutter or Expo.
github.com/MobAI-App/ios-bui…
There’s also an open source alternative that’s been doing this for months, and it’s not limited to React Native:
Swift, Flutter, React Native and Expo.

Seeing SimSlim being used by @openclaw in their CI feels kinda surreal.
Didn’t think it would go this far when I first had the idea.
github.com/openclaw/openclaw…
It’s quite good for controlling mobile apps and running e2e tests.
It’s already in the latest MobAI version, so give it a try locally or in CI:
mobai.run

We are introducing Clef and Clef-flash, open-source decision models hosted on Workers AI for high-speed classification and agentic workflows. cfl.re/3Vlqb9P #BirthdayWeek
