# Composal vs Apache JMeter

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

JMeter generates protocol-level workload and performance evidence. Composal uses a browser to check web journeys and exploratory behavior at the user interface.

## 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.

## Apache JMeter

Protocol-based load and performance testing

Apache JMeter is an open-source Java application for load testing functional behavior and measuring performance across web applications and many other protocols. Its supported areas include HTTP, REST and SOAP services, databases, messaging, FTP, and TCP.

### 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?
