Spotify has announced that it has built a development environment called "Xirp" to manage parallel sessions for multiple agents and avoid vendor lock-in, as thousands of its engineers across hundreds of teams utilize AI coding agents on a daily basis.

Xirp is designed to simultaneously manage over 50 parallel sessions across multiple harnesses, such as Claude Code, Gemini CLI, and Codex. Each session operates within an independent worktree, enabling parallel work on the same codebase without interference. According to Spotify, context is not tied to a specific agent or harness, allowing the work state to be maintained even if tools are switched mid-project. Furthermore, the architecture allows for switching models during a task or routing to the most cost-effective option, including self-hosted open-weight models.
Spotify positions Backstage—which it has long built as the foundation of its internal developer platform—and its externally available version, Portal, as the basis for this approach. The company explains that Xirp functions as a mechanism to ensure organizational visibility and consistency while maintaining the flexibility for engineers to select the optimal tool for each occasion.
