Upwatch vs Uptime Kuma: Cloud-Hosted vs Self-Hosted Monitoring

The Honest Comparison

Uptime Kuma is a great open-source project. I used it for years before building Upwatch. This isn't a hit piece — it's a breakdown of the tradeoffs so you can pick the right tool for your situation.

The Core Difference

Uptime Kuma is self-hosted. You run it on your own server, manage the updates, and own the data.

Upwatch is cloud-hosted. You sign up, add URLs, and monitoring starts in 30 seconds. We run the infrastructure.

Everything else follows from that one decision.

Feature Comparison

When Uptime Kuma Is the Better Choice

You want maximum control. You own the server, the data, and every config file. Nobody can change your pricing or deprecate a feature.

You need 90+ notification services. Uptime Kuma supports everything from Telegram to Gotify to ntfy to Pushover. Upwatch supports email, Slack, Discord, and webhooks.

You need specialized check types. DNS monitoring, Docker container health, Steam game servers, MQTT brokers — Uptime Kuma has check types we don't.

You have the infrastructure already. If you're running a homelab or already have a VPS with Docker, adding Uptime Kuma is free and takes 5 minutes.

You want unlimited everything for free. Uptime Kuma has no caps. Unlimited monitors, unlimited retention, unlimited check frequency. If you have the hardware, there's no ceiling.

When Upwatch Is the Better Choice

You don't want to maintain another server. The number one failure mode of self-hosted monitoring: the monitoring server goes down and nobody notices because the thing that would have noticed is the thing that went down.

You're a solo dev or small team. You want to add a URL and get an email when it breaks. You don't want to SSH into a box, docker compose up, configure Nginx, get a Let's Encrypt cert, set up backups, and then hope you remember to update it quarterly.

You want monitoring to be someone else's problem. Upwatch's infrastructure is monitored by Upwatch. Our workers, database, and API are checked continuously. If something breaks on our end, we know before you do.

You want a public status page with a custom domain. Both tools have status pages, but Upwatch handles SSL provisioning for custom domains automatically (status.yourcompany.com with zero config beyond a CNAME).

You need an API for automation. Upwatch has a full REST API on all plans — create monitors, query uptime, manage status pages programmatically. Good for CI/CD pipelines that spin up monitors for staging environments.

You value your time at more than $5/month. The math: Uptime Kuma takes ~30 minutes to set up, ~15 minutes/month for updates and maintenance, and costs $5-12/mo for a VPS. Upwatch takes 30 seconds to set up, zero maintenance, and costs $0-5/mo. Over a year, that's 3+ hours of your time saved.

The Self-Hosted Monitoring Paradox

This is the thing nobody talks about:

If you self-host your monitoring on the same cloud provider as your production infrastructure, and that provider has an outage, your monitoring goes down at the same time as your production services. You find out from Twitter, not from your alerting.

Upwatch runs on separate infrastructure. If your AWS region goes down, your Upwatch monitors still check from outside and alert you.

If you self-host Uptime Kuma on a different provider specifically to avoid this, you're now maintaining two cloud environments and paying for both. At that point, $5/mo for Upwatch is cheaper and simpler.

What We Don't Do (Yet)

Being honest about the gaps:

• No SMS alerts — pending carrier verification, coming soon
• No DNS monitoring — on the roadmap
• No Docker container checks — we check HTTP/TCP/ICMP, not container health
• No Telegram/Pushover/ntfy — we support Slack, Discord, and webhooks. If your service has a webhook URL, it works.
• No unlimited retention — 7 days free, 30 days Pro. Uptime Kuma stores data forever if you have the disk space.
• Not open source — Uptime Kuma is MIT licensed. Upwatch is a commercial SaaS.

The Bottom Line

Use Uptime Kuma if you enjoy running infrastructure, want maximum flexibility, need 90+ notification services, or philosophically prefer self-hosted software. It's an excellent project.

Use Upwatch if you want monitoring that works in 30 seconds with zero maintenance, you don't want to babysit another server, and you'd rather spend $5/month than 3+ hours per year on upkeep.

They solve the same problem differently. Pick the one that matches how you want to spend your time.

Full disclosure: I used Uptime Kuma for over a year before building Upwatch. It's a fantastic tool. I built Upwatch because I wanted the features without the maintenance. If self-hosting is your thing, Uptime Kuma is the best option out there.
