# Composal vs Appium

Appium supplies a platform-extensible automation layer, especially useful for native and hybrid app checks. Composal targets hosted web QA and its Scenarios, Discovery and browser-based Findings.

## Composal

Composal sends AI browser agents to use your running web app and check the outcomes you care about. Define journeys as plain-English Scenarios, map existing flows with Discovery, or explore for bugs with Deep Scan. Runs keep recordings and reproduction steps so your team or coding agent can investigate a Finding.

## Appium

Cross-platform UI automation ecosystem

Appium is an open-source ecosystem for UI automation across mobile, browser, desktop, TV and other platforms. It uses drivers and client libraries so tests can be written with different languages and frameworks.

## What each tool does

| Workflow | Composal | Appium |
| --- | --- | --- |
| [Run browser journeys](https://composal.com/product/scenarios) | ✓ Yes: Run saved browser Scenarios and return recordings and reproducible Findings. | ✓ Yes: Runs authored UI journeys across supported mobile and web environments. |
| [Map application workflows](https://composal.com/product/discovery) | ✓ Yes: Discovery maps key application areas and user journeys. | – Not confirmed: Check whether this product includes this workflow in your intended plan and setup. |
| [Explore for unexpected issues](https://composal.com/product/deep-scan) | ✓ Yes: Deep Scan explores the running application and reports reproducible issues. | – Not confirmed: Check whether this product includes this workflow in your intended plan and setup. |
| [Describe checks in plain English](https://composal.com/product/scenarios) | ✓ Yes: Author Scenarios around the intended user outcome, then review the steps and expected results. | – With setup: Write executable tests, scripts, or structured keywords to define the steps and expected results. |
| [Run or inspect from a terminal](https://composal.com/product/cli) | ✓ Yes: Use the CLI to start and inspect verification runs and their Findings. | – With setup: Run configured tests through the product’s supported developer tools or CI integration. |

With setup means you supply code or configuration. Not confirmed means support for this workflow needs checking with the vendor.

## Where each fits

Choose Appium when installed apps, native device behavior or a broad platform ecosystem are required. Choose Composal when you need browser verification for a web application and reproducible evidence for an engineering agent.

## Try this evaluation

Evaluate one responsive web workflow and one native app flow if relevant. Compare how much of the requirement each tool covers, device setup needs, debugging artifacts and how results reach the code owner.

### Coverage

Which user outcomes must this release prove, and which specialist checks must stay in your existing stack?

### Setup

Who prepares accounts, test data, permissions and access to the deployment being tested?

### Evidence

Can the engineer reproduce a reported failure from the recording and steps, without asking the tester to investigate again?

### Ownership

Who updates the checks when the product changes, and can the team review what a passing result actually proves?
