We are currently living through the great flattening of the interface. For most, the interaction with artificial intelligence has been relegated to a lonely text box—a clean, white void where a single prompt yields a single answer. But Ogulcan Celik sees the future of labor differently. He sees it as a sequence of concurrent processes, a noisy and productive workshop where multiple minds work on the same problem from different angles. To realize this, he didn't build a new web app; he went back to the terminal.

His project, Herdr, is less of a tool and more of a philosophy on workflow. It acts as an agent multiplexer, a term that sounds technical but feels visceral in practice. If you have ever watched a seasoned developer dance between windows in a terminal multiplexer like tmux, you understand the rhythm of high-intensity building. Celik is bringing that same energy to the world of large language models. Instead of treating an agent like a distant oracle, Herdr treats it like a subprocess. By allowing locally hosted or cloud-based intelligences to live directly in the shell, he has collapsed the distance between the code being written and the intelligence helping to write it.

What makes Celik’s approach notable is his rejection of the 'black box' mentality. Most agentic frameworks try to hide the complexity of the machine’s thought process behind a loading bar. Herdr leans into the chaos of the command line. It assumes the user is an operator, not just a consumer. When you spin up multiple agents to tackle a task, you aren't just sending a request into the ether; you are managing a team. You see the stream of consciousness, the recursive loops, and the failures in real-time. It is a return to the ethos of the early web, where tools were built to be manipulated rather than merely used.

Celik’s work reminds us that the best software often comes from a personal itch for efficiency. By building a tool that thrives in the terminal, he is speaking to the builders who never left it. He understands that for a professional, the context switch is the enemy. Moving from a code editor to a browser tab to ask a question is a tax on creativity. By multiplexing these identities within the existing developer environment, Celik is quietly arguing that the next era of computing isn't about escaping our tools, but about making them more populated with the agents that can help us finish the job. It is a gritty, functional, and deeply human way to organize the machines.
