# Composal vs Checksum

By Composal. Sources reviewed: 2026-10-15.

Evaluate how a suite is derived and how new behavior gets covered. Composal offers explicit Scenarios and separate Discovery and Deep Scan workflows for mapping journeys and exploring failures.

## 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.

## Checksum

AI-generated regression coverage

Checksum creates AI-generated Playwright and API tests and helps maintain regression coverage as an application changes. Its published workflow addresses test creation and ongoing suite maintenance.

## Where each fits

Consider Checksum for its approach to generating regression coverage. Consider Composal when teams want to specify expected outcomes directly and investigate behavior beyond the saved journeys.

## Try this evaluation

Provide a new feature with no historical traffic and an existing high-traffic flow. Compare the coverage created for each, editable expectations and failure evidence.

### 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?
