Spotify Says AI Tool Now Writes and Deploys Its App Code

Executives describe Honk moving engineers into oversight roles, with AI handling routine coding.

Overview

  • Co‑CEO Gustav Söderström said the company’s best developers have not written a line of code since December 2025, confirming the shift on Spotify’s Q4 earnings call.
  • An internal system called Honk uses Anthropic’s Claude Code and Slack-based ChatOps to generate, test and deliver builds that engineers can review and merge to production.
  • Spotify credits the workflow with faster velocity, citing more than 50 app features and changes shipped in 2025 and recent launches including Prompted Playlists, Page Match and About This Song.
  • Leaders stress that engineers are not being replaced, noting their responsibilities now center on reviewing AI output and making architecture and product decisions.
  • The company highlights a proprietary music dataset as a key advantage for model training and says AI-created tracks can be labeled in metadata as it continues policing AI-generated spam.
