Evaluate its specific platform coverage and suite-management model. Composal focuses its QA workflow on browser Scenarios, application Discovery and exploratory Deep Scan sessions.

## Composal

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.

## Where each fits

Consider Testsigma for a unified automation platform across your test estate. Consider Composal when your priority is checking web outcomes around previews, releases and coding-agent changes.

## Try this evaluation

Ask each tool to cover one core journey and a related negative case. Compare authoring, execution evidence and the maintenance caused by a frontend redesign.

### 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?
