Why Go for Network Tooling
Python has been the default language for network automation for years. But for production tooling — collectors, agents, API servers — Go is a better fit.
Single Binary, Zero Dependencies
A Go binary runs anywhere with zero runtime dependencies. No virtualenvs, no pip installs, no version conflicts. Ship a container with FROM scratch and a single binary. Your deployment surface is as small as it gets.
Concurrency for Polling
Network tools poll hundreds or thousands of devices simultaneously. Go's goroutines handle this naturally. A SNMP poller that manages 10,000 concurrent device connections fits in 50MB of memory. Try that with Python threads.
Strong Typing Catches Bugs
Network protocols are full of structured data — IP addresses, ASNs, BGP communities, VLAN IDs. Go's type system catches misuse at compile time. A netip.Addr can't accidentally become a string and break a template.
