Herdr joins Y Combinator F26, open-source agent runtime stays free

Herdr is joining Y Combinator. The runtime stays open

Herdr is a runtime and TUI for CLI coding agents, letting agents run persistently across machines. Solo developer Can Celik built it to 25k GitHub stars and 340k downloads, and is now joining Y Combinator's F26 batch to turn it into a company. The runtime stays free under Apache-2.0, the core remains small, and everything else goes through plugins—over 500 already exist, plus community-built Raycast, Stream Deck, and iOS clients. The post doesn't disclose funding amount or team size.

Why it matters: Solo dev takes a CLI agent runtime to 25K stars and 340K downloads, then joins YC F26 while keeping the core Apache-2.0 open. The story has contrast, numbers, and an open-source commitment that resonates with agent builders. Downside: it's a single blog post, not a product lau...

The numbers here are concrete: one person, four months, 25k GitHub stars, 340k downloads, and now YC F26. Can Celik is upfront about it—he was job hunting, didn't like any agent tools he tried, so he built a runtime and TUI that keeps CLI coding agents running persistently across machines.

I'd discount the post a bit: no funding amount or team size disclosed, and it's still a solo project. But the product direction is clear—tiny core, everything else through plugins. The community already shipped 500+ plugins plus Raycast, Stream Deck, and iOS clients. Switching from AGPL to Apache-2.0 signals a deliberate move to lower enterprise adoption friction.

The interesting bit isn't "another YC AI company." It's his line: don't give me another agent, let my agent integrate with your product. That runs opposite to the past year's flood of standalone coding agents. He's positioning for the agent runtime layer, not the agent itself.
