How the trade-offs apply to your team
Guidance below is inferred only from catalog differences. It is not a winner pick.
Consider mabl if…
- you need coverage for Android Applications, Angular Applications, Cloud Applications, GraphQL APIs
- your team writes tests in .NET, Any, TypeScript
- you want a free trial before committing
- you want a lower-complexity tool
Consider Selenium if…
- you need coverage for Internet Explorer, Opera
- your team writes tests in Kotlin
- you want a free or freemium starting point
- open source matters for your team
Questions to verify before choosing
- Confirm current pricing and packaging on the mabl and Selenium websites.
- Trial both tools against a real slice of your application, not a demo site.
- Verify the exact browser, device, or OS matrix you must support.
- Check what the free trial actually includes (users, minutes, devices).
