Two workflows, side by side

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.

Where each fits

Choose BrowserStack when you need hands-on debugging or automation across a large matrix of real browsers and devices, especially for mobile-specific behavior.

Try this evaluation

Use one staging build with a responsive checkout and an account requiring authentication. Run the same steps in Composal and on two BrowserStack browser/device combinations.

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?
