Katalon Studio vs Playwright

From $84 per seat/month (Professional, billed annually; $184 month-to-month)

Free and open source

The seat price is only part of it: CI execution needs add-ons priced separately — Runtime Engine at $145/licence/month and cross-browser or mobile device sessions at $158/session/month — so a parallel CI setup costs several times the headline seat figure.

Free and open source. Microsoft also sells a hosted parallel-runner service; the library itself has no paid tier.

Free plan covers local authoring and execution for web, mobile and API.

• 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.

• Auto-waiting and web-first assertions remove most of the sleep() flake that plagues older tools.
• The trace viewer — DOM snapshots, network, console and screenshots per step — is the best failure triage in the category.
• True WebKit support, so Safari bugs are caught on Linux CI without a Mac.

• 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.

• No native mobile app support. Mobile means an emulated viewport, not a real device.
• The API surface is large; teams without a conventions document end up with four ways to write the same locator.
• Component testing is still experimental compared to the E2E runner.

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

Teams that write their own tests and want the lowest-flake open-source option available.
