One person builds 25k Stars in 4 months—Agent edition tmux into YC
According to Beating monitoring, Herdr joined Y Combinator F26. It can be understood as a tmux made specifically for Coding Agents: run Claude Code, Codex, Cursor, etc. inside it, unify them in the background, switch between them, and check their status. Even if you close the terminal or disconnect SSH, the Agent can keep running. Regular tmux only manages the terminal; Herdr also knows which Agent is working, which one is waiting for your reply, and which one has already finished. Agents can also message each other and wait for each other to complete. As developers start running more and more Coding Agents at the same time, tools like this are made to solve the problem of “how to manage a bunch of Agents.” Herdr previously was developed by only Can Celik. After going live for 4 months, it has already garnered about 25k GitHub Stars, 340k downloads, and the plugin marketplace saw 500+ new plugins in a single month. Now the project has joined YC; the core runtime continues to be free and open-source, and the license has been relaxed from AGPL to Apache 2.0.
