# Composal vs Tricentis Tosca

Tosca is designed for coordinated, reusable enterprise test portfolios across supported systems. Composal offers a focused hosted path from web Scenarios through exploratory Findings and reproduction evidence.

## 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.

## Try this evaluation

Select one business workflow that crosses a web screen and a permission boundary. Compare modeling effort, execution ownership, how a new edge case is added and whether the final report isolates the user-visible defect.

### 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?
