Slusaj.rs is a locally developed audiobook platform created to make literature in the Serbian language more accessible to modern listeners.
Slusaj.rs was built from the ground up with a focus on stability, performance, and user experience across devices.
From the outset, Slusaj.rs had to overcome several technical and functional challenges to meet the expectations of an evolving audience:
Designing a scalable audio streaming system with minimal latency
Ensuring multi-platform compatibility across desktop, mobile, and tablets
Developing a user-friendly interface optimized for long listening sessions
Implementing a secure and flexible subscription model
Managing and organizing a growing library of audio content
The development team at Nine Pixels engineered a complete digital ecosystem tailored for audio content:
Admin panel for uploading, categorizing, and managing audiobook metadata
API-driven architecture for integration with future mobile apps and third-party tools
Secure playback and access control, ensuring only authorized users can stream content
Analytics module for tracking listening patterns, engagement, and content popularity
Since launch, the platform has shown strong technical performance and supported rapid user adoption:
99.98% uptime across all systems
Rapid onboarding of new titles with minimal manual intervention
Optimized audio encoding and delivery, keeping bandwidth usage efficient
Smooth scalability as the user base and content library grew
We wanted a solution that gives users a frictionless way to enjoy audiobooks — and that meant building something from the ground up, without relying on generic templates or prebuilt platforms. Every feature was tailored for the experience we envisioned.
