# Composal vs Semgrep Code

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

Semgrep analyzes source code for security issues. Composal checks a running web application against user requirements and records browser evidence; functional QA does not replace SAST.

## 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.

## Semgrep Code

SAST and customizable code security analysis

Semgrep Code scans repositories and CI changes for security vulnerabilities using inspectable rules and data-flow analysis. Its current platform also includes AI-supported detection, triage, and remediation workflows.

## Where each fits

Choose Semgrep for configurable source scanning and security workflows. Choose Composal for hosted browser Scenarios, Discovery, and exploratory testing. Use separate gates for security and runtime behavior.

## Try this evaluation

Scan a change to authorization code with Semgrep and run its preview through Composal. Compare security findings with observed allowed and denied journeys, keeping remediation and QA evidence distinct.

### 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?
