What Users Actually Say
Sauce Labs User Feedback
For more on Sauce Labs issues, see Sauce Labs Not Working? Common Fixes.
G2 Reviews (4.3/5 stars):
“Running extensive test suites on real devices can sometimes be slower than local environments, especially when dealing with large-scale parallel testing.”
— Verified G2 Review, 2024
“Its price is high for small business which can be improved.”
— G2 Review
“Latency, due to Sauce Labs being a cloud-based solution, has been a concern. We work in different continents and countries, but Sauce Labs was only offering two data centers, one in the EU and another in the US. If you’re not in either of those two places, you would have latency issues.”
— PeerSpot Review
“We have used Sauce Labs extensively for the last 5 years… during automated testing this can be very slow. This causes inconsistencies with the tests.”
— PeerSpot Review
“Once you pay for yearly subscription, they only interested you to buy additional services and do not fix your issues for ages.”
— Capterra Review, 1-star
LambdaTest User Feedback
G2 Reviews (4.6/5 stars):
“The license cost of LambdaTest is lower than other similar tools in the market.”
— G2 Review
“Performance issue in real device testing - it is very slow sometimes even the internet is stable.”
— TrustRadius Review
“LambdaTest offers testing of application on all types of devices thus ensuring the product quality. The speed of execution of UI Automation suites in LambdaTest is very efficient.”
— TrustRadius Review
“Requested iPhone 14 Pro for testing, got an emulator instead. No warning, no notification. Discovered only when device-specific features failed.”
— Capterra Review, 2024

“Running tests in the SauceCloud can take longer than running in a local environment.”
— PeerSpot Review
LambdaTest:
“Real devices are little bit laggy.”
— TrustRadius Review
Neither matches local device speed.

- Longer enterprise track record (since 2008)
- Already using it (migration has costs)
- US/EU data centers sufficient
When to Choose LambdaTest
- Lower cost priority (~20-35% cheaper)
- Teams in Asia-Pacific need lower latency
- React Native with Detox support
The Third Option: Your Own Devices
Both platforms share cloud limitations: latency, data exposure, concurrency costs. Learn how to set up your own private device cloud.
| Factor | Sauce Labs | LambdaTest | Your Own Devices |
|---|---|---|---|
| 10 devices (annual) | ~$24,000 | ~$15,000-19,000 | $10,692* |
| Data location | Their cloud | Their cloud | Your network |
| Latency | Cloud-based | Cloud-based | Local |
*DeviceLab pricing: First device free, then $99/device/month. 10 devices = 9 × $99 × 12 = $10,692/year.
