For legacy browser support before a front-end release, the best all-around choice is usually BrowserStack.

Why BrowserStack is often the best fit

  • Very broad legacy coverage: real devices and real browsers, including older Windows/macOS versions and Internet Explorer/legacy Edge where applicable.
  • Reliable for release gating: stable infrastructure, good automation support, and easy integration with CI/CD.
  • Manual + automated testing: useful if you need both quick spot checks and full regression runs.
  • Good debugging tools: screenshots, video, logs, network capture, console output, etc.

Strong alternatives

  • Sauce Labs: also excellent for automation-heavy teams and enterprise workflows; often compared directly with BrowserStack.
  • LambdaTest: usually cheaper, broad browser coverage, and a good option if budget matters.
  • CrossBrowserTesting (SmartBear): decent, but less commonly the top pick for large teams today.

If you specifically care about very old legacy browsers

Check whether the platform supports:

  • IE 11 / old EdgeHTML
  • Older Safari on macOS
  • Older Android/iOS versions
  • Specific Windows versions you need for enterprise users

Practical recommendation

  • Best overall: BrowserStack
  • Best enterprise automation alternative: Sauce Labs
  • Best budget-conscious option: LambdaTest

If you want, I can also give you a comparison table by legacy browser support, automation, pricing, and CI integration.
