Sauce Labs Inc., a continuous testing solutions provider, today announced the general availability of its Real Device Access API, changing how the company delivers mobile testing infrastructure and making it easier for developers to test software directly on real devices.

The new Real Device Access application programming interface removes the need to work through traditional automation frameworks and exposes low-level device access as “programmable infrastructure.” Sauce Labs says it’s designed to eliminate costly testing constraints, allowing engineers to allocate devices in seconds.

“We are releasing industry’s first modern, programmable, mobile quality cloud to really enable developers with deep device level controls especially as they think about AI driven mobile workflows,” Chief Product Officer Shubha Govil told SiliconANGLE in an interview.

Govil said modern developers often lack deep observability when it comes to device-level data. To understand where a slowdown is coming from, teams need to know whether a device is heating up, what’s driving it or whether there’s a memory issue unfolding under the hood.

Instead of being constrained by automation frameworks, developers can pull device logs and vitals directly, manage apps and files and issue low-level device commands. The idea is to diagnose what’s happening at the device layer, not just the user interface.

Think of it like a house: The user interface is flipping light switches and turning faucets. Device-level access is opening the walls and getting instruments on the wires and plumbing to see what’s actually happening behind the switch plate and under the floorboards.

Engineers can stream high-fidelity video streams, use Model Context Protocol-ready architecture, view logs and maintain sessions up to 24 hours, all accessible through HTTP requests.

“That’s the last leg, the last mile of testing — how the app is performing on a real device… [with] that level of explicit control over the device,” Govil explained.

This isn’t just functional testing. The pitch is faster visibility into performance and stability problems that show up only on real hardware. That can matter most for teams pushing devices to the edge or needing long-running stability windows, including gaming studios and endurance-style testing.

Build for real-world use cases

Gaming studios try to squeeze the last erg of performance out of screens and graphics. Knowing why a display is hitching or why frame rates dip can mean the difference between a smooth session and a churn event — sometimes with real revenue impact.

On the stability side, teams may need to run an app for hours at a time to confirm it won’t accumulate errors and crash. That becomes difficult if you don’t have enough devices available concurrently or can’t keep sessions alive long enough to reproduce problems.

Artificial intelligence-heavy and highly dynamic applications can consume more memory, involve more device interaction and require deeper diagnostic collection. Govil argued that without that diagnostic depth, many developers fall back on a device-on-desk workflow and limited visibility. With a cloud-access approach, teams can scale across as many devices as they need at once, capture logs and crash analysis and refine their understanding of how an app behaves in the wild.

Beyond app teams, Govil said, Sauce Labs is also seeing demand from partners building enterprise-grade synthetic monitoring and observability products that run on top of real-device infrastructure. For these customers, Real Device Access has become a dependable layer on which other companies can build services.

Real Device Access will not be charged per API call. Instead, Sauce Labs will sell it as an add-on priced per device, on top of the Real Device Cloud access customers already purchase as part of their packages.
