 Browserstack offers two APIs for browser testing:
  - [Browserstack JS Testing](https://www.browserstack.com/javascript-testing-api)
  - [Browserstack Automate](https://www.browserstack.com/automate)
- 
- JS testing supports more types of devices (compare: [JS Testing devices](https://www.browserstack.com/list-of-browsers-and-platforms?product=js_testing) 
- vs [Automate devices](https://www.browserstack.com/list-of-browsers-and-platforms?product=automate)), 
- while Automate allows for much longer tests ([2 hours](https://www.browserstack.com/automate/timeouts) vs [30 minutes](https://github.com/browserstack/api#timeout300))
