# Composal vs SmartBear ReadyAPI

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

ReadyAPI addresses service-level testing and can cover functional, security, and performance checks around APIs. Composal checks browser-facing application behavior through Scenarios and exploratory sessions.

## 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.

## Where each fits

Choose ReadyAPI when API validation spans multiple protocols or requires centralized functional, security, and performance workflows. Choose Composal when the important release evidence is user-facing browser behavior and exploratory QA of a web app.

## Try this evaluation

Take an API-backed workflow with a successful response, an authorization failure, and a slow dependency.

### 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?
