The short version

  • Only Bun has a free tier, so it costs nothing to try first.
  • Each has a real cost: BrowserStack automate entry plans (Chrome $59/month, Desktop $99/month) include only 1 parallel test session per plan, requiring a higher paid tier to run tests concurrently, per browserstack.com, August 2026; Bun linux requires kernel 5.6 or higher (5.1 minimum but with compatibility issues); older systems not supported
