# Composal vs WebdriverIO

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

WebdriverIO provides one programmable setup across several application surfaces and testing styles. Composal concentrates on hosted web QA: Scenarios, Discovery, Deep Scan and evidence for agent handoff.

## 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 WebdriverIO when a JavaScript team needs to share test conventions across browser, mobile or desktop coverage. Choose Composal when the immediate need is to verify a running web app and return actionable findings.

## Try this evaluation

Test a web journey plus one mobile or desktop interaction if both are in scope. Compare the value of WebdriverIO’s shared runner against Composal’s exploratory findings and the time spent adapting the same test.

### 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?
