Compare Scripted UI frameworks
AskUI vs Appium
Open-source mobile automation through the UI tree, compared with AskUI's agent that works from the screen.
Appium · open source
What it is.
Appium is an open-source framework for mobile and desktop app automation. It drives apps through platform automation frameworks and their UI element tree. Engineers write tests in code.
Where Appium is strong
- Free and open source, with drivers for many platforms.
- Precise element access where the UI tree is complete.
- Works with common test runners and device farms.
Side by side
How they work.
Architecture, not adjectives.
| Question | Appiumopen source | AskUIComputer-use agent |
|---|---|---|
| How a test finds the UI | Elements from the platform's UI tree, by ID, accessibility label or XPath. | An agent reads the screen like a tester does. No selectors, no object repository, no recordings. |
| How tests are written | Code, in the language of your test runner. | Plain language. Your manual test cases, often written from requirements. |
| Surfaces | iOS, Android and, through drivers, some desktop platforms. | Desktop and remote computers, web browsers, Android emulators and phones, iOS simulators, several computers in one test, and embedded screens with no DOM. |
| Access needed to the app | The app's UI element tree through platform automation frameworks. | None. No source code, instrumentation or accessibility tree. AgentOS gives the agent screen, keyboard and mouse. |
| When the screen is not as expected | Runs code exactly as written. Predictable, and stops at an unexpected screen. | The agent decides each next action from the screen. It closes unexpected pop-ups and corrects its own misclicks. Two attempts per step; In-Flight Guidance stops runs that loop; Dreaming proposes fixes for review. |
| Integrations beyond the UI | Anything a library of your test language can reach, written in code. | Tool Store: SQL over ODBC, HTTP, shell and file checks, off until enabled. Custom C# tools and MCP servers, for example Vector CANoe or dSPACE, called from plain-language steps. |
| Where it runs | Anywhere, including your own CI and network. | Your machines and your CI. On-premise and air-gapped, with your own model. |
| Test format | Code in your repository. | Markdown, CSV or JSON files in your own Git repository. |

Which one fits
Both are good at something.
Choose Appium when
Your mobile app exposes a complete UI tree and developers maintain the tests in code.
Choose AskUI when
The screen is rendered by a game engine, a canvas or an embedded system without a usable UI tree, or testers write the tests.
Questions
- Does AskUI work on Android phones?
- Yes. AskUI drives Android emulators and phones, and iOS simulators, from the screen.
