Domain DMARC Checker
Another DNS record checker in a sea of Mail-Tester and MXToolbox clones.

Clean IP checker with VPN detection, but ipinfo.io already does this better.
Remote workers verifying VPN connections, developers needing IP lookup APIs

I originally built this tiny project a few years ago but ended up abandoning it. I recently revived and finished it to solve a very specific, recurring annoyance I had with my usual workflow.
Whenever I turn on my VPN, I always want a quick visual confirmation that it’s actually routing correctly before I start browsing, usually by just checking what city/country I appear to be in.
The frustration was that whenever I googled "what is my ip" and clicked a random result, half the sites were bloated with ads, required scrolling past walls of SEO text, or bizarrely buried the actual location data (or didn't show it at all).
So I revived https://whereismyip.info/
It does two things on load:
Shows your IP and exact location front and center. Checks the ASN and automatically flags if you are connecting through a known datacenter or commercial VPN. (Also, since I live in the terminal, I added a JSON route: `curl https://whereismyip.info`).
It’s obviously free, and the source is just a lightweight Flask backend with a vanilla HTML/CSS/JS frontend (using Leaflet for the map), all routed through Caddy.
I'd love to know what you think or if your VPN ASN bypasses the detection (I know there are but the list is infinite :D)
Another DNS record checker in a sea of Mail-Tester and MXToolbox clones.
Updates status via email instead of an app, but lacks automatic presence detection.
Hardened *arr stack with actual VPN namespace isolation, not just firewall rules.
Clean, focused product: email alerts, response-time tracking, and instant public status pages with a forever-free 2-monitor tier make it easy to get started. It isn't reinventing monitoring, but the stripped-down pricing and one-click status publishing feel deliberately built for solo founders — missing advanced alerting (SMS/pager/on-call tooling) and broader integrations keeps it squarely aimed at small shops.
FeatureFlag and Canny clone that works, but offers no new angle on the problem.
Yet another URL checker with MCP integration in a crowded category.
