Step 4 failed
The flow report stops at the tap. With Argent, the agent keeps going: it checks the screen, whether the button sent its request on iOS and what covers the button.
Argent vs. Maestro MCP
Your Maestro flows guard the release. Then a flow goes red, and the report says step 4 failed. Accurate, and not much help.
Maestro MCP lets the agent write those flows, run them and keep them for CI. Argent helps the agent find out why step 4 failed: it drives the app, checks each screen, reads network requests on iOS and profiles the slow parts.
Based on each tool's public documentation, checked October 20, 2026.
Debugging loop or release gate: Argent and Maestro MCP side by side
Both put a coding agent in front of a live iOS simulator or Android emulator. Maestro MCP is built around the test the agent leaves behind. Argent is built around what the agent can find out while the app is still running.
| Feature | Argent | Maestro MCP |
|---|---|---|
| Built for | An agent that builds, debugs and profiles the app in one session | An agent that writes and maintains end-to-end UI tests |
| Platforms | iOS, Android, Apple TV, Android TV, Fire TV, Electron and Chromium apps | iOS, Android and web (Chromium, in beta) |
| Physical iPhones | Over USB, with a subset of the simulator tools | Not supported yet. iOS simulators only |
| Physical Android devices | Over adb | Supported |
| When a step fails | Screenshots and the element tree on demand, plus the native view tree on iOS. In React Native apps, also console logs | No debugging tools. Screen hierarchy and screenshots only |
| Network requests | Request URLs and status codes on the iOS simulator, no proxy. On Android, JavaScript apps only. Not in Flutter apps yet | Not included |
| Performance profiling | Xcode Instruments on iOS, with a severity and a suggested fix for each finding. Perfetto on Android, with the UI freezes it found | Not included |
| Saved test flows | Recorded YAML flows, replayed by the agent or by argent e2e run in CI | Maestro YAML flows, Maestro Studio and the Maestro CLI |
| Device clouds | BrowserStack, AWS Device Farm, Limrun and TestMu AI, plus Argent Cloud with dedicated iOS simulators | Maestro Cloud with hosted Android, iOS and web devices. Maestro flows also run on BrowserStack (beta) |

Tested where e2e frameworks stop
“I've been using argent almost daily since last week. Really simplifies my workflow. I've noticed it's faster than maestro in reading screens and finding things on the screen.”

What the agent can do after a Maestro flow goes red
A green flow on a slow screen
Flows check that things happen, not how fast. Argent profiles the slow screen and shows the agent each freeze, and on iOS what caused it.
The bug only shows up on a real iPhone
Maestro doesn't support physical iPhones yet. Argent drives one over USB, signed with a free Apple Personal Team.
Your flows on Argent Cloud, too
Argent Cloud runs the stock Maestro CLI on hosted iOS simulators, even from Linux CI. When a flow fails, the agent can debug it there with Argent.
Questions from Maestro users
Fix it before the flow goes red
Keep running your Maestro flows while your agent debugs and profiles the app with Argent. When it suits you, record them again in Argent, one at a time.
