• 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.

• Genuinely usable by non-technical staff — the flowchart model is easier than any script-behind-a-recorder approach.
• Covers Citrix, virtual desktop and mainframe environments that most tools cannot touch.
• Doubles as an RPA platform, which can consolidate two budgets.

• 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.

• Flowcharts do not diff or merge, so version control is essentially unusable.
• Complex logic becomes an unreadable sprawl of blocks.
• Enterprise pricing with no small-team entry point.

Teams already on BrowserStack who want an integrated JavaScript framework.

Enterprises where business users must own automation and Citrix or mainframe is in scope.
