Composal vs Gatling

Gatling models traffic and analyzes performance at scale.

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.

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?
