Home Network Device Testing
Got a Raspberry Pi, a NAS, or a home server? Build a quick dashboard to check if they're all reachable.
How It Works
The Custom List page lets you add any URLs you want to check. Your list gets encoded into the page URL itself. No account needed, nothing stored on a server. Bookmark it and you've got a one-click connectivity check for all your devices.
Add your device URLs
Go to /custom and add the HTTPS addresses of your devices. Examples:
https://pi.local(Raspberry Pi with mDNS)https://192.168.1.50:8443(NAS web interface)https://homeassistant.local:8123(Home Assistant)https://mynas.local:5001(Synology DSM)
Bookmark the URL
Your list is compressed and stored in the page URL (the # part). Bookmark it, add it to your home screen, or share it. The list travels with the link.
Check anytime
Open the bookmark on any device on your network. Each URL gets an instant connectivity check, showing whether it responded and how fast.
What the Results Tell You
Your browser sends a real HTTPS request to each URL and measures the round trip. For local network devices, here's what to expect:
| Result | What It Means |
|---|---|
| ✓ Responded < 20ms | Device is up and on your local network. All good. |
| ✓ Responded 20–200ms | Device is reachable but slower than expected. Could be Wi-Fi congestion or the device is under load. |
| ✗ No Response | Device is off, crashed, or not reachable from this network. Check power, cables, Wi-Fi. |
| ⏱ Timed Out | Request was sent but no reply within 30 seconds. Device might be overloaded or firewall is blocking. |
Things to Know
HTTPS only
Browsers only let web pages make HTTPS requests. If your device only serves plain HTTP, you'll need to set up a self-signed certificate or use a reverse proxy like Caddy or nginx. Most modern home server software (Home Assistant, Synology, etc.) supports HTTPS out of the box.
CORS won't matter much
Most home devices don't send CORS headers, so you'll see "Responded" instead of an HTTP status code. That's fine. All you need to know is whether the device answered.
Server probes won't work for local devices
The "Check from servers" button sends a request from our servers on the internet, so they can't reach 192.168.x.x or .local addresses. That feature is only useful for public URLs. For local devices, the browser check is all you need.
Works on your phone too
Can I Connect? is a PWA. Install it from your browser (no app store required) and it's ~200KB total. Walk around your house checking Wi-Fi dead spots by bookmarking a list of your devices.
