# Composal vs SoapUI

By Composal. Sources reviewed: 2026-10-15.

SoapUI is focused on API and service behavior, including protocols that browser-centric QA does not exercise directly. Composal tests a running web experience and reports outcomes from Scenarios or exploratory Deep Scan.

## 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.

## SoapUI

Open-source SOAP and REST service testing

SoapUI Open Source is a graphical tool for building functional tests of SOAP and REST services.

[Official product or project documentation](https://www.soapui.org/docs/open-source/)

## Where each fits

Choose SoapUI when a team needs accessible SOAP or REST functional tests and can own the test project and its execution.

## Try this evaluation

Choose one SOAP or REST operation that supports a browser task. Create a SoapUI test for its request, response, and an error case.

### 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?
