• Unmatched coverage of enterprise packaged software, especially SAP end-to-end processes.
• Model-based design means one change updates every affected test case.
• Risk-based prioritisation is a real answer to eight-hour regression packs.

• 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.

• Expensive, and priced for organisations with a procurement department.
• Steep learning curve; most customers buy consulting alongside the licence.
• Heavy and slow compared to modern code-first tools for plain web applications.

• 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.

Large enterprises running SAP or similar packaged systems where no open-source tool reaches.

Teams already on BrowserStack who want an integrated JavaScript framework.
