Block AI telemetry at the kernel level.
Firewall Sentinel is a lightweight, offline-first network utility designed for Ubuntu-based creative and development environments. It helps users maintain awareness of outbound connections initiated by local applications—particularly useful when running open-weight AI models or self-hosted tools that may attempt to reach external services. This tool operates entirely on-device with no telemetry, cloud dependencies, or remote analytics. It uses standard Linux firewall interfaces (iptables/nftables) to provide real-time visibility into network activity, allowing users to optionally block non-essential domains such as update checkers, crash reporters, or third-party APIs. Designed for artists, developers, and privacy-conscious creators, Firewall Sentinel integrates silently into your workflow—no daemons, no background phoning home, no automatic updates. Just pure, transparent control over what your machine talks to. Includes pre-configured blocklists for known AI/ML telemetry endpoints (e.g., OpenAI, Anthropic, Google Cloud APIs), which can be reviewed, modified, or disabled at any time via plain-text configuration files. Key Features: 100% offline operation Zero data collection Human-readable allow/block rules One-command enable/disable (firewall-sentinel --enable) Compatible with LM Studio, Ollama, and local LLM runners Ships as a standard .deb package for Ubuntu 22.04+ For those who believe your AI stack should serve you—not report on you.
