Visual Network Firewall Rule Builder and Manager

C5/10March 30, 2026
WhatA desktop/web app that provides a visual drag-and-drop interface for building, testing, and deploying nftables/iptables firewall rules with plain-English explanations of what each rule does.
SignalMultiple commenters note that nftables syntax is hard to read and that while the underlying networking concepts are simple, the configuration tooling remains hostile — people explicitly say they're glad to use a web UI instead of wrestling with terminal-based firewall config.
Why NowThe migration from iptables to nftables is actively happening across Linux distros, creating a wave of users who need to relearn firewall configuration — and LLMs can now power real-time plain-English translation of complex rule sets.
MarketDevOps engineers, sysadmins, and homelab enthusiasts managing Linux firewalls; ~2M+ active Linux server admins; competes with ufw/firewalld (CLI-only) and OPNsense's web UI (tied to their OS).
MoatBuilding a library of validated, community-shared rule templates creates a network effect — the more users contribute tested configurations for common scenarios, the more valuable the platform becomes.
