Summary
Spotify has shipped Xirp (pronounced “chirp”), a free open-beta Mac application that lets developers run up to 50 AI coding agents simultaneously — including Claude Code, OpenAI Codex, and Gemini CLI — within a single interface on a shared codebase. The tool was used internally by 1,300 Spotify engineers before its public release. Creator Magic’s host provides a detailed hands-on walkthrough covering setup, core features, and one notable gap he patches live.
Key capabilities include session persistence via tmux (agents keep running even after closing the app), a built-in browser for previewing output, per-session token usage visibility, and hot-swapping between AI coding agents mid-session without losing context — switching from Claude Fable 5 to Codex mid-build, for instance, while Xirp maintains the session state. A grid view lets users monitor multiple parallel sessions simultaneously, with keyboard shortcuts for session management and switching.
The one missing feature the host identifies is mobile notifications: with 14+ agents running in parallel, there’s no native way to get alerted when an agent completes or gets stuck. He solves this in about ten minutes by wiring Xirp’s session hooks to a Zapier webhook connected to a Telegram bot, demonstrating that the hook system is extensible even where native integrations are absent. For developers already working with Claude Code CLI or Codex, Xirp offers a practical way to parallelize workloads across multiple concurrent AI sessions.
