Just the Beginning: 8 Billion Tests and Counting

Many companies toss around the word “scale” to try to differentiate themselves in crowded markets. But real enterprises running 8 billion tests on our infrastructure to validate and qualify their applications shouldn’t feel like hyperbole to anyone. That’s scale for real, and it’s something for all of us to celebrate.

Earlier this year, when Sauce Labs surpassed 8 billion customer tests executed on our cloud, it wasn’t a surprise. Nor that this figure stands head and shoulders above other offerings – we are the only test automation platform that enables continuous quality across both the web and mobile applications landscape, for pre-production (supporting left-shifting developers and fully integrated into CI pipelines) and production, with real-time error reporting and insights.

I am beyond proud of this milestone, so I want to take this opportunity to reflect on how we got here, highlight some of our amazing customers' success, and toast to a very bright, testing future. 

At the core of Sauce Labs is the market's most robust and enterprise-ready infrastructure. With over 9,000 (and counting) real devices across public and private clouds and almost every possible combination of virtual devices, Sauce Labs infrastructure offers the coverage, flexibility, and compliance standards required by the largest and most complex organizations around the world. According to our 2024 Continuous Benchmark Report, Sauce Labs customers assess their products across 70 different devices on average!

We also support over 800 browser and OS combinations, alongside 1,700+ emulators and simulators on our Virtual Device Cloud - the most scalable in the industry. This enables our customers to run high-volume, fast, and efficient test automation on the broadest range of environments. 

We are also delighted to announce that iOS 17.5, iOS 18, and Mac OS 14+ simulators were released on our virtual device cloud in April. Sauce is the only provider delivering this capability at massive scale - with reliability and coverage that enterprise teams need. With the majority of iPhone users already on iOS 18 or higher, this update ensures our customers can confidently test on the latest and greatest OS versions, delivering the highest-quality app experience possible.

“With Sauce Labs [infrastructure], we can test all of the platform combinations we know are being used by agents and homeowners in the market so that every person can connect and find their dream home effortlessly.” - Keller Williams 

On top of our infrastructure sits industry-leading performance and speed. Sauce Labs now offers the most performant emulators and simulators in the industry - dramatically improving both session start and test execution times. And the performance speaks for itself — on the latest iOS 18 versions, customers are seeing up to 40% faster test execution and 65% faster session start time based on their own benchmarks. 

"We've already observed a significant improvement in our test execution speed, with performance improving to sub 20 seconds for a simulator to load, which is a fantastic experience," reports a Global Retail Brand. 

This speed advantage holds true across the platform. In a study conducted last year, most organizations (77%) execute tests in less than 2 minutes on Sauce Labs infrastructure with average test run times of just 92 seconds. According to Forrester’s Total Economic Impact of Sauce Labs, customers experience 90% faster test execution with Sauce Labs compared to alternative solutions.

At the core of our testing platform lies AI technology that delivers intelligent insights throughout your software development lifecycle. Our AI-driven insights, available today, transform raw test data into actionable trends, empowering your team to make informed decisions with confidence. These answer questions before they are asked – what should I be testing? Where is my coverage the weakest? What are the latest test runs hinting at, what has regressed, on what platform and when? The sort of queries app owners worry about every morning and spend hours or days poring over data to extract.

As the only comprehensive solution for continuous quality, we unify AI-powered insights at every stage of development—from functional and visual testing across real and virtual devices, to mobile app distribution and beta testing, through post-production error reporting. All in one unified, intelligent solution. 

And this is just the beginning. We’re continuously innovating with more exciting solutions set to launch later this year that will further enhance your team's ability to release exceptional digital experiences with complete confidence. Stay tuned! 

Modern testing started with Sauce Labs, and our roots run deep as leaders in the industry. We're proud to be the company started by the founders of Selenium, Appium, and WebDriverIO—the foundational technologies that power modern testing. We recently sponsored the Selenium conference in Valencia (March 2025), and our team includes two of the top five Selenium contributors of all time and chairs of the Selenium leadership committee.

Today, that legacy powers our enterprise-grade platform, partnering with global brands on test strategy. We offer the most secure and compliant solution in the market, with certifications including ISO 27701, ISO 27001, SOC 2 Type II, and KY3P. With deep test expertise, professional services, and customer support, we help industry leaders like Walmart, Bank of America, and Microsoft deliver large-scale digital experiences.

As we celebrate this remarkable milestone showcasing customer confidence and trust, our focus remains clear: to deliver the most innovative, performant, and reliable testing platform in the world. With unmatched infrastructure, deep testing expertise and commitment to customer success, Sauce Labs is uniquely positioned  lead the future of continuous quality.
