Looking for a Uptime Kuma alternative?

Uptime Kuma is free software, but real cost is a VPS ($5–$20/mo), your time to install, upgrade, and back it up, plus a second monitor to watch the monitor.

FourSight Free ($0/mo): 10 monitors, multi-region consensus, email alerts, a hosted status page — no server, no maintenance.

FourSight Starter ($16/mo) and Growth ($40/mo): more monitors, faster intervals, all 7 check types, Slack/webhook/SMS alerts, and incident management — cheaper than building reliable self-hosted monitoring for most teams.

Pick FourSight when self-hosting is a liability, not a hobby.

• You don't want to be paged because the box hosting your monitor went down.
• You need monitoring that's independent of your own cloud account or region.
• Multi-region quorum consensus is required and a single-instance Kuma can't provide it.
• Your time is better spent on the product than on Kuma upgrades and backups.

Uptime Kuma is still a great choice in specific contexts.

• You're running a homelab or learning project where ops work is the point.
• You need to monitor internal-only endpoints that aren't reachable from the public internet.
• Compliance or data-residency rules require monitoring to stay inside your own infrastructure.
• Software cost matters more than the hidden ops cost of running it.

Why move from Uptime Kuma to a hosted service?

Self-hosted monitors share fate with your infrastructure — if your VPS or cloud region goes down, the monitor can go down with it. A hosted service like FourSight runs independently and checks from multiple regions.

Can I keep Uptime Kuma and use FourSight too?

Yes — many teams run Kuma internally and use FourSight as the external, multi-region watchdog. FourSight's free tier is designed for exactly this.

How do I migrate from Uptime Kuma?

Export your monitor list from Kuma (URL, type, interval) and recreate them in FourSight. The Free plan covers 10 monitors with multi-region consensus out of the box.

Can FourSight monitor my internal network?

FourSight probes from public regions, so it can only reach internet-routable endpoints. For internal-only checks, keep Uptime Kuma (or another internal agent) running inside your network and have FourSight monitor Kuma's status page as the bridge.

What's the real cost of self-hosting Kuma?

A small VPS is $5–$20/mo, plus your time for upgrades, TLS, backups, and a second monitor to watch the box. For commercial use that's often more expensive than FourSight Starter once you cost in time honestly.

Will my Kuma data import into FourSight?

Monitor definitions can be recreated quickly from the Kuma backup JSON. Historical uptime data does not import — most teams keep Kuma running read-only for a transition period if they need history for SLA reporting.

Is FourSight as feature-rich as Kuma?

Different shape. Kuma supports a long list of niche check types; FourSight focuses on the seven most-used types and adds hosted multi-region quorum, status pages, and incident management around them.
