A BEHIND-THE-SCENES LOOK AT HOW WE RELEASE THE SPOTIFY APP

Summary from the TLDR Web Dev newsletter

Spotify's Release team manages weekly app updates to over 675 million users through a structured two-week cycle. The process begins with trunk-based development and nightly builds to alpha users, followed by branching the release in week two for more intensive testing. Rollout happens in two phases: 1% of users, then 100%, as this allows quick issue identification while balancing speed and quality.
