Code quality and security

Composal vs Semgrep Code

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.

Two workflows, side by side

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.

What each tool does

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

Composal and Semgrep Code workflow capabilities
Workflow	Composal	Semgrep Code
Run browser journeys	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	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	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	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	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 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?
