Geo-specific QA & localization

OTP & push notifications

Real hardware. German infrastructure. Anywhere access.
Emulators and VPNs approximate the real world. We give you the real world.
Real devices, not emulators
Every session runs on a genuine, physical smartphone — real chipsets, sensors, and rendering behavior emulators cannot fully replicate.
Hosted in Germany
Our device fleet is physically hosted and operated in Germany, giving you authentic local IP addresses and network conditions.
GDPR-compliant by design
Data residency, access controls, and processes are built around German and EU data protection requirements.
A German infrastructure company for real-device testing
Stealthlink was founded to close the gap between simulated testing environments and how apps, ads, and content actually behave on real phones, on real networks, in Germany.
We operate and maintain the device fleet, the network connectivity, and the remote-access software, so your team can focus on what you learn from the real world — not on managing hardware.
