.net
Born alongside .com in 1985, .net was meant for network operators, and it never lost that flavor. It reads as technical and established, which is exactly right for infrastructure, tooling, and developer-facing projects.
It is also the strongest fallback when your .com is taken: universally recognized, no explaining needed, and far better availability for short, clean names.
