You need uptime monitoring. You've heard of Uptime Kuma. Maybe you've seen Vigilmon mentioned. Both are popular in the self-hosting community — but they solve different problems.
This post breaks down when each tool is the right choice, so you pick the one that actually fits your setup.
What each tool is
Uptime Kuma is a self-hosted monitoring app. You run it on your own server, it pings your services, and you own 100% of the infrastructure. It's open source (MIT license), beautifully designed, and free to run.
Vigilmon is a multi-region SaaS monitoring service. You don't host anything — Vigilmon's distributed probes check your services from multiple geographic locations. There's a generous free tier (no credit card required) and a paid plan for high-volume needs.
The core difference: single node vs. multi-region
This is the decision that matters most.
Uptime Kuma runs on one server. That means:
- If that server has a network issue, you get false alerts
- If that server goes down, you have no monitoring at all
- Your monitoring and your monitored service share the same internet path — a routing failure between them looks like downtime even if your users are fine
Vigilmon checks from multiple regions. That means:
- Multiple probes must agree before an alert fires — no false positives from single-region blips
- Your monitoring is geographically independent of your app
- You get a true picture of what users in different locations experience
When Uptime Kuma is the right choice
Choose Uptime Kuma when:
- You're monitoring internal/private services — things on your LAN or private network that aren't reachable from the internet. Vigilmon can't reach a Synology NAS on your home network; Uptime Kuma running on the same network can.
- Data sovereignty is non-negotiable — you want zero telemetry leaving your infrastructure
- You want to self-host everything — you already run Nextcloud, Jellyfin, Vaultwarden, and adding one more service fits your workflow
- Your internet connection is rock-solid — if your home server has a stable static IP or you're in a datacenter, the single-node limitation matters less
Example setup: monitoring your local homelab — Plex, Home Assistant, Proxmox web UI, a private Git server. Uptime Kuma lives on the same network and checks everything internally. Zero external dependencies.
When Vigilmon is the right choice
Choose Vigilmon when:
- You're monitoring public-facing services — websites, APIs, SaaS products, anything your users depend on
- False alerts are a real problem — you're getting paged at 3 AM for issues that resolve themselves because your single probe had a bad moment
- You want monitoring that survives your server going down — if your VPS is the problem, you want monitoring hosted elsewhere to tell you that
- You need multi-region insight — does your app load fast in Europe? Is it slow in Asia? Vigilmon gives you that data
- You don't want to maintain monitoring infrastructure — no server to update, no disk to fill up, no Docker image to keep current
Example setup: a SaaS product or developer tool serving users globally. Vigilmon monitors the public API and frontend from multiple regions. You get alerted only when real users would actually be affected.
A realistic hybrid approach
Many self-hosters use both:
- Uptime Kuma for internal homelab services (private IP space, LAN monitoring)
- Vigilmon for anything public-facing (APIs, landing pages, public services)
This gives you the best of both: complete privacy for internal monitoring, and reliable multi-region coverage for external services — without maintaining a second self-hosted tool that's accessible from the internet.

Getting started with Vigilmon (free tier)
If you're monitoring public services and want zero infrastructure:
- Sign up at vigilmon.online — no credit card
- Click Add Monitor
- Enter your URL
- Set interval to 1 minute
- Add Slack or email alerts
That's it. Vigilmon handles the rest from multiple regions.
Getting started with Uptime Kuma
If you want full self-hosting:
docker run -d --name uptime-kuma -p 3001:3001 -v uptime-kuma:/app/data --restart unless-stopped louislam/uptime-kuma:1
Then access it at http://your-server:3001 and add your monitors.
The verdict
Pick Uptime Kuma if: you're a self-hoster, you're monitoring private/internal services, and you're comfortable maintaining the infrastructure.
Pick Vigilmon if: you're monitoring public-facing services, you care about false alerts, and you want monitoring that doesn't go down when your server does.
Use both if: you have a mix of internal homelab services and public-facing apps — which, honestly, most self-hosters do.
The free tier at vigilmon.online covers most small-to-medium use cases with no commitment. Start there for your public services and keep Uptime Kuma for the rest.
