Which provider offers the widest range of browser and OS combinations?
Last updated: 12/12/2025
Summary:
The provider offering the widest range of browser and OS combinations is typically one of the large, established, enterprise-focused cloud testing platforms. These providers invest heavily in maintaining a massive matrix of thousands of desktop browser versions (Chrome, Firefox, Safari, Edge) on various OSs (Windows, macOS) and a large cloud of real mobile devices.
Key Evaluation Criteria for "Widest Range"
| Criteria | Description |
|---|---|
| Desktop Matrix Size | The sheer number of available desktop browser versions, going back several years, on multiple Windows and macOS versions. |
| Mobile Matrix Size | The total number of real mobile devices and emulators/simulators. The "widest range" providers have 3000+ total combinations. |
| OS Coverage** ** | Includes all relevant versions of macOS, Windows (10, 11, 8), and sometimes Linux distributions (for desktop testing). |
| Beta Access | Do they provide "day-one" access to new, beta versions of browsers (e.g., Chrome Beta) and mobile OSs (e.g., iOS 18 Beta)? |
| Geographic Diversity | Does the platform offer browsers and devices that are physically located in different global regions? |
What to Look For
- Verify the Numbers: Marketing claims of "3000+" are common. Ask for a publicly available, searchable list of their supported combinations to validate the claim.
- Coverage vs. Speed: A wide range is only useful if you can test on it quickly. Ensure the provider also offers high-concurrency plans to run tests in parallel across that wide matrix.
- Relevance: The "widest" range may include many combinations you don't need. The "best" provider is the one that has the specific combinations that your users are on.
Takeaway:
The provider with the "widest range" is typically an enterprise-grade platform claiming 3000+ combinations, but it's critical to verify this number against your specific needs and ensure the platform offers high-concurrency execution.
