The mobile toolkit your coding agent was missing.

With MobAI, Claude Code, Codex, Cursor or any coding agent runs your iOS and Android app while it writes the code. It checks every change on simulators and real phones, turns those checks into tests and runs them in CI. On your machine or in the cloud.

Works with the agent you already use

Claude Code, Codex, Cursor, OpenCode, Cline or the agent built into MobAI.

local

On your machine

Install the desktop app for macOS, Windows or Linux. MCP is built in, and MobAI connects Claude Code, Codex, Cursor and others for you.

cloud

In the cloud

Your agent runs in Claude Code on the web, Codex cloud or Cursor background agents? It can still preview the app, build for iOS and ship to TestFlight. From Claude Code or Cursor it can also use your iPhone. No Mac on your desk.

01devices

Your agent uses the app

It taps, types and reads the screen on simulators and real phones, then checks its own changes before you do.

It reads the UI tree, takes screenshots and streams device logs, so it sees the same screen you do. It works with Claude Code, Codex, Cursor or the agent built into MobAI.

Test on a real iPhone from macOS, Windows or Linux. No Mac required.

02testing

A full testing framework

Plain-text Workflows and precise .mob scripts. Agents write the tests, run them and fix them when the UI changes. The dashboard keeps your runs.

Already on Maestro? Most YAML flows run without changes, even on a real iPhone.

03ci

Your tests in any CI

Run the same tests in GitHub Actions or any other CI. Each run keeps the screen at every step, plus a video and logs when you turn them on.

One command, mobai-ci test ./tests, runs your Workflows, .mob scripts and Maestro flows.
