• Removes the maintenance burden entirely — no flaky-test triage on your side.
• You own the Playwright code, so leaving is possible.
• Coverage arrives in weeks rather than quarters.

• 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.

• It is headcount, not software — the cost profile is completely different from a licence.
• External team needs deep product context to test meaningfully.
• Fast-moving products can outpace the feedback loop with an external author.

• 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.

Funded startups that need coverage now and have no QA hire in the plan.

Teams already on BrowserStack who want an integrated JavaScript framework.
