Composal vs Selenium

Selenium is a flexible automation foundation that teams compose with their preferred language, runner and infrastructure. Composal is a hosted QA workspace that adds saved Scenarios and exploratory browser Findings.

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.

Selenium

Standards-based browser automation

Selenium WebDriver is a language-neutral browser-control interface that drives browsers locally or remotely. Its project documentation describes browser-specific drivers and WebDriver BiDi for bidirectional browser events.

Where each fits

Choose Selenium when your organization needs a standards-based foundation, language choice or existing Grid investment. Choose Composal when you want teams and agents to direct web verification without assembling the browser harness.

Try this evaluation

Take one role-based workflow already covered by Selenium. Compare the work to add a new expected outcome, inspect browser evidence and reproduce an intentionally introduced authorization regression.

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?
