Gatling models traffic and analyzes performance at scale.

## 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.

## Gatling

Performance tests as code with scalable execution

Gatling supports performance testing with code-based simulations in Java, JavaScript, and other supported languages, plus browser recording and a no-code builder in its platform. Its documentation covers CI execution and scaling tests through Gatling Enterprise. Teams can model request flows and user injection profiles, then analyze performance results.

## Where each fits

Choose Gatling when performance testing is a release requirement and your team wants test-as-code, browser recording, or managed distributed execution.

## Try this evaluation

Select a journey with a known request sequence and a realistic peak-traffic profile.

### 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?
