A developer has shipped Zeroserve, a web server that replaces configuration files with eBPF scripting.
The premise is straightforward: instead of writing nginx.conf or a Caddyfile, you write eBPF programs — sandboxed bytecode that runs inside the Linux kernel — to control how the server behaves. The project bills itself as zero-config, meaning there is nothing to configure in the traditional sense; the eBPF code is the configuration. It was introduced this month via a blog post by its author.
eBPF has spent the last few years becoming the plumbing layer of choice for serious Linux networking work. Cilium uses it for Kubernetes networking. Falco uses it for runtime security. Applying it to web serving is a different direction — less infrastructure plumbing, more application-layer programmability. The appeal is control without abstraction layers, though "less config" and "write kernel bytecode instead" are not obviously the same thing.
Fifteen upvotes on Hacker News puts Zeroserve somewhere between "interesting experiment" and "solution looking for a problem" — which is about where any eBPF side project should expect to land.
