Karate is a programmable framework for service-level checks and automation.

## 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.

## Karate

Code-based API test automation and service tooling

Karate is a framework for API testing with a readable feature-file syntax, request construction, response assertions, data-driven scenarios, and parallel execution.

[Official product or project documentation](https://docs.karatelabs.io/)

## Where each fits

Choose Karate when API tests need code-level control, readable scenarios, reusable features, or integration into an existing JVM/CI setup.

## Try this evaluation

Model one checkout or approval flow in Karate with response and authorization assertions, then define the matching web outcome in Composal. Introduce an API contract defect and a frontend state defect separately.

### 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?
