The 3 Best UptimeRobot Alternatives in 2026

Uptime Kuma is the self-hosted answer here, and one of the most-starred projects on GitHub. One Docker container gives you HTTP(S), keyword, JSON-query, TCP, ping, DNS, WebSocket, Docker and push monitors at intervals down to 20 seconds, with multiple status pages mapped to your own domains and alerts to Telegram, Discord, Slack, SMTP and 90-odd other services. Version 2 is current. The catch is one every self-hosted monitor has: if it runs on the same box, region or provider as the thing it watches, it goes down with it. Host it somewhere your outage cannot reach.

• Free and unlimited, with no per-monitor pricing
• Runs on the smallest VPS you can buy
• Polished UI for a self-hosted tool

Instatus positions itself directly against Atlassian Statuspage: a status page that loads quickly, looks good by default and includes uptime checks, so one product covers both halves of the job. The free Starter plan allows 15 monitors, 200 subscribers and five team members, but no custom domain. Pro is $20/month ($15 annually) and adds a custom domain, 30-second checks, 5,000 subscribers and 50 team members. There is nothing between Pro and Business at $300/month ($225 annually), which is where private pages and SAML SSO live. Instatus renders its pricing client-side; the paid figures were confirmed against two independent 2026 write-ups.

• Status page and uptime monitoring in one bill
• A branded page on your domain for $20
• Fast, clean pages out of the box

Statuspage is the incumbent: the page behind a large share of the status.* subdomains you have seen during an outage. It is a communication tool rather than a monitor. You connect Datadog, Pingdom, Opsgenie and the like, or post updates by hand, and it notifies subscribers by email, SMS, Slack and webhook. Public pages are free up to 100 subscribers and 25 components, then $29 (Hobby), $99 (Startup), $399 (Business) and $1,499 (Enterprise) a month, scaling on subscribers and team members. Private pages for internal tools start at $79/month, and audience-specific pages at $300.

• The status page customers and enterprise buyers recognise
• Deep integrations with Jira, Opsgenie and major monitoring tools
• Mature subscriber notifications across email, SMS and Slack
