Show HN: Twsnmp FK – Lightweight NMS Built with Go, Wails, and Svelte
twsnmp Sunday, February 15, 2026
Hi HN, developer here.
I’ve been developing and maintaining a network management tool called TWSNMP for about 25 years. This new version, "FK" (Fresh Konpaku), is a complete modern rewrite.
Why I built this: Most enterprise NMS are heavy, server-based, and complex to set up. I wanted something that runs natively on a desktop, is extremely fast to launch, and provides deep insights like packet analysis and NetFlow without a huge infrastructure.
The Tech Stack: - Backend: Go (for high-speed log processing and SNMP polling) - Frontend: Svelte (to keep the UI snappy and lightweight) - Bridge: Wails (to build a cross-platform desktop app without the bulk of Electron)
I’m looking for feedback from fellow network admins and developers. What features do you find most essential in a modern, lightweight NMS?
