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.

Puppeteer

JavaScript browser automation

Puppeteer is a JavaScript library for controlling Chrome or Firefox through DevTools Protocol or WebDriver BiDi. The project documents browser automation, testing recipes, screenshots and PDF generation.

Where each fits

Choose Puppeteer for custom scripts, browser tooling or tests close to a Node application. Choose Composal when product teams need to express browser outcomes and share reproducible QA evidence with engineers.

Try this evaluation

Automate an account-settings journey with Puppeteer, then ask Composal to verify the same expected result and explore adjacent settings. Compare code ownership, time to broaden coverage and clarity of the failure report.

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?
