# Composal vs reviewdog

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

reviewdog transports source-analysis diagnostics into review workflows; the underlying analyzers determine what it can detect. Composal checks user-visible browser behavior and creates reproducible QA Findings.

## 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.

## Where each fits

Choose reviewdog when your team wants to surface existing linter output on pull requests. Choose Composal for runtime web QA. Pairing them preserves both static diagnostics and execution evidence.

## Try this evaluation

Wire one existing linter through reviewdog and select a changed browser flow for Composal. Compare how each result is triaged, whether it points to the responsible code or user outcome, and time to reproduce.

### 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?
