Composal vs OWASP ZAP

ZAP probes web application security properties. Composal checks product requirements and user-visible behavior in browser journeys. Composal is not a security scanner and does not replace ZAP.

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.

OWASP ZAP

OWASP ZAP is an open-source web application security scanner and proxy. It supports automated and manual security testing workflows, including crawling and active scanning of applications.

Where each fits

Choose ZAP when authorized dynamic security testing is required. Choose Composal for functional browser QA and reproducible product Findings. A release process can run both with distinct security and product criteria.

Try this evaluation

Use an isolated authorized test environment. Run a scoped ZAP scan and a Composal journey for the same feature; compare security alerts with functional outcomes, then keep their triage criteria separate.

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?
