• Everything included: runner, assertions, page objects, reporting, parallelism.
• Very readable chained syntax that non-specialists pick up quickly.
• Tight BrowserStack integration if you already use that cloud.

• Natural-language tests remain readable by stakeholders while executing deterministically.
• Bundles visual, accessibility and API checks that would otherwise be three purchases.
• Strong story for migrating away from an unmaintainable Selenium suite.

• Community is a fraction of Playwright's or Cypress's; fewer answers exist for edge cases.
• WebDriver-based, so it carries the usual latency and waiting caveats.
• Corporate stewardship by a device-cloud vendor is worth weighing if you plan to use a competitor.

• Enterprise-only pricing and sales motion.
• Tests live in the vendor cloud, not your repository.
• Smaller ecosystem and community than the incumbents.

Teams already on BrowserStack who want an integrated JavaScript framework.
