Get help & get involved
Guardian is a community open-source project — there's no call center, and that's by design. Help comes straight from the people who build and use it. Looking for setup how-tos? See Getting Started.

The quick answers most people are after.
Is it really free? +
The core app is free and open-source under GPL-3.0 — no license fee to run it, and you can always self-host. Some advanced features may be offered as optional paid add-ons in the future to help sustain development, but the core monitoring and protection will stay free. Your only required cost is the off-the-shelf hardware you choose.
What hardware do I need to get started? +
At minimum, a LinkTap valve + gateway for water control, or a Shelly Flood Gen4 for leak detection. You can start with one system and add the others over time. The Supported Devices page lists kits and individual parts with prices.
Does it work without internet? +
Yes — Guardian is local-first. When your device is on the same Wi-Fi as your sensors and gateway, it talks to them directly with zero latency and no internet. Cloud mode kicks in automatically when you leave, so you keep remote alerts and control.
Is my data private? +
Your real-time readings stay on your local network unless you explicitly enable cloud sync. Cloud sync only exists to deliver remote alerts and control when you are away — and since the project is open-source, you can verify exactly what it does.
Which platforms are supported? +
Web (any browser), native macOS and Windows desktop apps (Tauri), and Android (Capacitor APK). An iOS build is on the roadmap; in the meantime the web app works on iPhone and iPad.
Can I contribute or request a feature? +
Absolutely — that is the whole point. Open an issue for bugs or ideas, start a discussion to ask questions, or send a pull request. Hardware suggestions from fellow boaters and RVers are especially welcome.
