Composal vs reg-suit
reg-suit provides visual comparison and lets teams compose storage and reporting around their own build system.
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.

Visual regression testing with pluggable storage
reg-suit is an open-source visual regression testing tool that compares screenshots from builds and supports pluggable storage and reporting integrations.
Read reg-suit's product documentation ↗Where each fits
Choose reg-suit when an open-source, configurable visual-diff step fits your CI design and you already have screenshot generation covered.
Try this evaluation
Choose a frontend repository that already generates screenshots and connect reg-suit to a small CI job with a deliberate reference update. In Composal, exercise the corresponding page as part of a user journey.
- 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?
