Herdr: Agent multiplexer that lives in your terminal

What happened

Developer Oğulcan Çelik released Herdr on June 28, a terminal-based multiplexer for AI agents that quickly trended on Hacker News.

Context and impact

The tool responds to the surge in "agentic" workflows where engineers run multiple instances of Claude Code, Codex, or Cursor in parallel. An open-source alternative competes with proprietary orchestrators and reflects developer demand for simple local tools.
