# Composal vs HeadSpin

HeadSpin focuses on mobile environments and the quality signals observed during those sessions. Composal focuses on web Scenarios and exploratory browser QA, returning user-journey Findings that teams can route through their development workflow.

## 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.
