In  of “How We Release the Spotify App”, we gave an overview of how the Spotify release process works. In Part 2, we will peek under the hood at the tooling that makes it possible.

The Spotify Engineering Blog provides  insights, technical deep dives, and behind-the-scenes stories from the engineering team at Spotify. Covering a wide range of topics, including backend systems, data processing pipelines, and frontend architecture, the blog offers a glimpse into the technology stack and engineering practices used to power one of the world's leading music streaming platforms. Developers can learn about scalable infrastructure solutions, innovative engineering techniques, and best practices for building high-performance software systems. By following the Spotify Engineering Blog, developers can gain inspiration, knowledge, and practical insights to apply to their own projects and endeavors.

Spotify built a custom Release Manager Dashboard in Backstage to centralize their mobile app release process. The dashboard aggregates data from 10+ systems into a single view, showing release states, blocking bugs, quality metrics, and sign-off status across Android, iOS, and Desktop platforms. They optimized backend performance through caching, reducing load times from minutes to 8 seconds. Analysis of time-series data revealed testing and App Store approval as major bottlenecks, leading them to build an automated 'Robot' that advances releases through states when conditions are met, cutting the average release cycle by 8 hours.
