Best VPS for Uptime Kuma in 2026

Your website goes down at 3 AM. Nobody notices until customers start complaining. Sound familiar?

Uptime Kuma is a free, self-hosted monitoring tool that watches your sites, APIs, and services around the clock — and alerts you the second something breaks. Think UptimeRobot or Pingdom, but you own it. No monthly fees, no monitor limits, no vendor lock-in.

With 50,000+ GitHub stars, it’s one of the most popular self-hosted projects ever. And the best part? It runs on a $3/month VPS.

Here’s which VPS to pick and how to get it running in under 5 minutes.

What is Uptime Kuma?

Uptime Kuma is an open-source, self-hosted monitoring tool built with Node.js and Vue.js. It gives you everything the paid monitoring services offer — for free.

Monitoring types:

• HTTP(s) — check if your websites and APIs respond
• TCP / Ping / DNS — monitor any network service
• Docker containers — watch container health directly
• Steam Game Server — monitor game servers
• MQTT / gRPC — IoT and microservice monitoring
• SQL queries — database health checks

Status pages:

• Beautiful, shareable status pages you can show clients and teams
• Custom domain support
• Group monitors by category
• Incident management built in

Notifications — 90+ integrations:

• Telegram, Discord, Slack, Microsoft Teams
• Email, Webhooks, Pushover, Gotify
• PagerDuty, Opsgenie, and dozens more

Other features:

• Certificate expiry monitoring — get warned before SSL certs expire
• Multi-language UI — 30+ languages
• Responsive design — works great on mobile
• Proxy support — monitor through SOCKS5/HTTP proxies
• Two-factor authentication — secure your dashboard
• Maintenance windows — suppress alerts during planned downtime
• API access — automate monitor creation
• Lightweight — single Docker container, SQLite database

Why Self-Host on a Separate VPS?

Here’s the most important rule of monitoring: your monitoring server must be independent from what it monitors.

If your monitoring runs on the same server as your app, and that server goes down — your monitoring goes down too. You’ll never get the alert.

A VPS in a different data center (or different provider entirely) gives you:

• Independent monitoring — if your production server dies, your monitoring VPS still sends the alert
• Full control — no monitor limits, no data retention caps, no upsells
• Privacy — your monitoring data stays on your server
• Cost savings — $3-5/month replaces $20-50/month SaaS plans

The cheapest VPS from a different provider than your production hosting is the ideal setup. Different network, different infrastructure, truly independent.

VPS Requirements for Uptime Kuma

Uptime Kuma is extremely lightweight. It’s just Node.js + SQLite in a single container.

Spec	Minimum	Recommended
CPU	1 vCPU	1 vCPU
RAM	512MB	1GB
Storage	5GB SSD	10GB SSD
OS	Any Linux	Ubuntu 22.04/24.04
Network	Unmetered preferred	Unmetered preferred

With 1GB RAM, you can comfortably run 100+ monitors at 60-second intervals. Uptime Kuma idles at roughly 100-150MB RAM — even the cheapest VPS is overkill.

This makes it a perfect “first self-hosted app” — tiny resource needs, immediately useful, and dead simple to set up.

Quick Setup Guide

Uptime Kuma runs in a single Docker container. Here’s the full setup in under 5 minutes.

Step 1: Connect to Your VPS

ssh root@your-server-ip

Step 2: Install Docker

curl -fsSL https://get.docker.com | sh

Step 3: Run Uptime Kuma

docker run -d \
  --name uptime-kuma \
  --restart=always \
  -p 3001:3001 \
  -v uptime-kuma:/app/data \
  louislam/uptime-kuma:1

That’s it. Open http://your-server-ip:3001 in your browser and create your admin account.

Step 4: Set Up Firewall

ufw allow ssh
ufw allow 80
ufw allow 443
ufw enable

Step 5: Add Reverse Proxy with SSL

For a proper domain with HTTPS, set up Nginx and Certbot:

apt install -y nginx certbot python3-certbot-nginx

Create the Nginx config:

cat > /etc/nginx/sites-available/uptime-kuma << 'EOF'
server {
    server_name status.yourdomain.com;

    location / {
        proxy_pass http://127.0.0.1:3001;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }
}
EOF

ln -s /etc/nginx/sites-available/uptime-kuma /etc/nginx/sites-enabled/
nginx -t && systemctl reload nginx
certbot --nginx -d status.yourdomain.com

Now your Uptime Kuma instance runs at https://status.yourdomain.com with a free SSL certificate.

Performance Tips

Tune Your Monitoring Intervals

• 60 seconds is the default — good for most monitors
• 30 seconds for critical services
• 300 seconds (5 min) for non-critical checks — reduces load and notifications

Don’t set everything to 30 seconds. Be intentional about what needs fast detection.

SQLite Optimization

Uptime Kuma stores all data in SQLite. For better performance:

• Keep data retention reasonable — 180 days is plenty for most setups
• The database auto-vacuums, but restarting Uptime Kuma monthly doesn’t hurt
• Monitor your disk usage — large histories can grow the DB

Backup Strategy

Backing up Uptime Kuma is dead simple — it’s just one Docker volume:

# Stop the container
docker stop uptime-kuma

# Copy the data volume
docker cp uptime-kuma:/app/data ./uptime-kuma-backup-$(date +%Y%m%d)

# Start it back up
docker start uptime-kuma

Or automate it with a cron job:

0 3 * * * docker cp uptime-kuma:/app/data /root/backups/uptime-kuma-$(date +\%Y\%m\%d) 2>/dev/null

Keep It Lightweight

• Don’t overload one instance — 100-200 monitors per instance is comfortable
• Separate your monitoring from production workloads
• Use Docker’s restart policy (--restart=always) so it survives reboots
• Update regularly — docker pull louislam/uptime-kuma:1 && docker restart uptime-kuma

Why Uptime Kuma wins: Unlimited monitors, no monthly fees, full data ownership, and a UI that looks professional enough to share with clients. The only cost is a $3/month VPS.

When to use a SaaS instead: If you need monitoring from multiple global locations simultaneously, or you don’t want to manage any infrastructure at all.

FAQ

How many monitors can Uptime Kuma handle?

On a 1GB RAM VPS, expect 100-200 monitors at 60-second intervals without issues. Users have reported running 500+ monitors on modest hardware. SQLite is the bottleneck at scale, not CPU or RAM.

Is there a mobile app?

No native app, but the web UI is fully responsive and works great in mobile browsers. You can add it to your home screen as a PWA. For notifications, use Telegram or Pushover — they deliver push alerts to your phone.

Does Uptime Kuma have an API?

Yes. Uptime Kuma exposes a Socket.IO-based API and a REST API for managing monitors, status pages, and notifications programmatically. There are also community-built CLI tools and Terraform providers.

Can multiple users access it?

Uptime Kuma supports a single admin account by default. For team access, share the dashboard URL with read-only status pages, or put it behind an authentication proxy like Authelia or Authentik for multi-user access.

Can I monitor from multiple locations?

Not natively — a single Uptime Kuma instance monitors from one location. For multi-location monitoring, you’d need to run multiple instances on different VPS providers and compare results. This is where SaaS tools like UptimeRobot have an advantage.

How do I update Uptime Kuma?

docker pull louislam/uptime-kuma:1
docker stop uptime-kuma
docker rm uptime-kuma
docker run -d \
  --name uptime-kuma \
  --restart=always \
  -p 3001:3001 \
  -v uptime-kuma:/app/data \
  louislam/uptime-kuma:1

Your data persists in the Docker volume — updates are seamless.

Is Uptime Kuma secure?

Yes. It supports 2FA, runs in an isolated Docker container, and stores data locally. For extra security, put it behind a reverse proxy with SSL and restrict access by IP or with an auth proxy.

Conclusion

Uptime Kuma is the best self-hosted monitoring tool available — beautiful UI, 90+ notification integrations, unlimited monitors, and it runs on the cheapest VPS you can find.

Our recommendations:

Use Case	Provider	Price
Best overall monitoring VPS	Hetzner CX22	€3.29/mo
Run multiple tools alongside	Contabo VPS S	€4.99/mo
First-time self-hosting	Hostinger KVM 1	$3.99/mo
Developer-focused setup	DigitalOcean	$6/mo
Specific region needed	Vultr	$6/mo

For most people, Hetzner at €3.29/month is the move. It’s cheap, reliable, and gives you 2GB RAM — more than Uptime Kuma will ever need. Spin it up, run the Docker one-liner, and you’ve got professional-grade monitoring for less than a coffee.

Remember: always run your monitoring on a separate server from what you’re monitoring. That’s the whole point. A $3 VPS watching over your $50/month production server is the cheapest insurance you’ll ever buy.
