# Composal vs Graphite Code Review

Graphite focuses on source review and organizing pull request stacks. Composal runs browser QA against the resulting application and preserves evidence for runtime regressions.

## 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.

## Graphite Code Review

AI review and stacked pull request flow

Graphite combines pull request management, stacked changes, and an AI reviewer that summarizes diffs and flags bugs. Its workflow centers on dependent changes.

## What each tool does

| Workflow | Composal | Graphite Code Review |
| --- | --- | --- |
| [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: Graphite combines pull request management, stacked changes, and an AI reviewer that summarizes diffs and flags bugs. Its workflow centers on dependent changes. |

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

## Where each fits

Choose Graphite when stacked pull requests and review collaboration are central to how your team ships. Choose Composal for repeatable browser verification and exploratory QA on previews. They can share a release workflow.

## Try this evaluation

Use a small stack that changes a visible feature. Review each diff in Graphite, then run the matching Composal Scenario against the integrated preview. Compare code comments with observed behavior and replay steps.

### 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?
