# Composal vs Review Board

Review Board organizes human review of proposed source changes. Composal runs browser checks against deployed behavior and stores recordings and reproduction steps, rather than managing diff discussions.

## 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.

## Review Board

Self-hosted collaborative code review

Review Board is an open-source platform for submitting changes, discussing diffs, and tracking review status. It documents review requests, repositories, and workflow integrations.

## What each tool does

| Workflow | Composal | Review Board |
| --- | --- | --- |
| [Run browser journeys](https://composal.com/product/scenarios) | ✓ Yes: Run saved browser Scenarios and return recordings and reproducible Findings. | × No: The documented product reviews or analyzes source changes; it does not execute browser journeys. |
| [Map application workflows](https://composal.com/product/discovery) | ✓ Yes: Discovery maps key application areas and user journeys. | – Not confirmed: Check whether this product includes this workflow in your intended plan and setup. |
| [Explore for unexpected issues](https://composal.com/product/deep-scan) | ✓ Yes: Deep Scan explores the running application and reports reproducible issues. | – Not confirmed: Check whether this product includes this workflow in your intended plan and setup. |
| [Describe checks in plain English](https://composal.com/product/scenarios) | ✓ Yes: Author Scenarios around the intended user outcome, then review the steps and expected results. | – Not confirmed: Check whether this product includes this workflow in your intended plan and setup. |
| [Run or inspect from a terminal](https://composal.com/product/cli) | ✓ Yes: Use the CLI to start and inspect verification runs and their Findings. | – With setup: Connect its specialist checks to your development workflow using supported integrations. |
| Source code review and analysis | × No: Use a dedicated tool for this specialist workflow alongside Composal’s browser verification. | ✓ Yes: Review Board is an open-source platform for submitting changes, discussing diffs, and tracking review status. It documents review requests, repositories, and workflow integrations. |

With setup means you supply code or configuration. Not confirmed means support for this workflow needs checking with the vendor.

## Where each fits

Choose Review Board when self-hosted review workflows and control over review infrastructure matter. Choose Composal for browser QA evidence and exploratory findings. Teams can connect both stages in a release process.

## Try this evaluation

Submit a small application change through Review Board and deploy its preview. Compare reviewer discussion with Composal checks for the affected journey; note whether either tool exposes missing acceptance criteria.

### 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?
