# Composal vs SonarQube

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

SonarQube analyzes code and configured rules. Composal exercises the running web app against browser expectations. Browser QA complements SonarQube and should not be treated as a substitute for static analysis.

## 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.

## SonarQube

Static analysis and quality gates for code changes

SonarQube Server and Cloud analyze source for reliability, security, and maintainability. Pull request analysis reports new issues and quality gate status.

## Where each fits

Choose SonarQube when code quality profiles, CI analysis, and quality gates are required. Choose Composal for deployed user journeys, exploratory browser checks, and Findings with reproduction evidence.

## Try this evaluation

Run Sonar analysis and a Composal Scenario on the same preview change. Compare new-code findings and quality gate results with user-visible outcomes; keep separate ownership for code and runtime risks.

### 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?
