Puppeteer vs Katalon Studio

Free and open source

From $175 per licence/month (indicative, annual)

Free and open source. You pay in engineering time and CI minutes.

Pricing is tiered by licence type (Studio, Runtime Engine, TestOps) and adds up quickly once you need parallel CI execution.

Everything, self-hosted

Katalon Studio Free covers local test creation and execution with limited features.

• Small, fast, and very well documented for Chrome-specific work.
• First-class access to the Chrome DevTools protocol for performance tracing and coverage.
• Excellent at non-test jobs: PDF rendering, screenshots, scraping.

• One tool spanning web, API, mobile and desktop, which avoids stitching four frameworks together.
• Manual testers become productive in days rather than months.
• Built-in reporting and test management reduce the number of separate purchases.

• No test runner, assertions, retries or reporting — you assemble all of it.
• Chrome and Firefox only; no WebKit.
• For E2E testing specifically, Playwright is a strict superset. Choose Puppeteer only when you want a minimal automation library.

• Record-and-playback suites become brittle at scale unless someone refactors them into keywords and objects.
• Proprietary project format makes migrating away expensive — real lock-in.
• Heavy desktop IDE; version control and code review are awkward compared to plain-text tests.

Automation jobs that are not tests, or Chrome-only tooling where you want minimal dependencies.

QA teams without dedicated automation engineers that need coverage across several platforms.
