RealUptime Monitor vs Healthchecks.io
Healthchecks.io is a focused dead-man's-switch monitor: your cron jobs, backups, and workers ping it, and silence triggers the alert. It is open source (BSD 3-Clause), self-hostable, run by a small business, and honest about its scope. This page compares it with RealUptime Monitor on that scope honestly: for pure cron monitoring the two overlap almost completely, and the real question is whether you also need your websites and services probed from the outside.
Cron and heartbeat monitoring
Have
heartbeat monitors on every plan including Free, sharing the same monitor slots and alert fan-out as every other check type
Have
its entire product, and a mature one: per-check schedules, grace periods, and log entries per check
Active uptime checks (HTTP, TCP, DNS) from outside
Have
probes your sites and services from multiple named regions, each reporting separately, by default
Don’t have
by design: it listens for pings from your jobs and alerts when they stop; it does not probe your site from outside
Free tier
Have
10 monitors (heartbeats included) plus 5 server-agent slots, $0/mo
Have
20 checks and 100 log entries per check, $0/mo, no card required
Open-source, self-hostable code
Don’t have
hosted only today
Have
BSD 3-Clause; the hosted service and the self-hosted code are the same product
Phone-call and SMS notifications
Don’t have
pages by email, Slack, webhook, and the integration registry (Discord, Teams, Opsgenie, PagerDuty, Zapier); no telephony of its own
Have
SMS, WhatsApp, and phone-call credits included on Business ($20/mo) and Business Plus ($80/mo)
Status pages from the same account
Have
RealUptime Status shares the account; public pages update from the same probes
Not published
no status-page product advertised on its pricing page
Is there a free tier?
RealUptime is free to start and never asks for a card. One signup turns on the free rung of every product: 10 monitors with a public status page, 5 server-agent slots, and 10,000 error events a month kept for 14 days. RealUptime Outages is free to read with no account at all.
Healthchecks.io: 20 checks and 100 log entries per check at $0/mo, with no card required.
Is it open source or self-hosted?
RealUptime's core is a hosted service and its source is not published, so there is no self-hosted edition of the platform itself. The parts that run on your side are open source at github.com/RealUptimeHQ: the CLI and the RealUptime Errors SDKs for JavaScript, Python, Go, PHP and Ruby are MIT-licensed, and the Grafana data source is Apache 2.0.
Healthchecks.io: BSD 3-Clause; the hosted service and the self-hosted code are the same product.
If self-hosting is a hard requirement, these are the open-source options in this category: Uptime Kuma (MIT), OpenStatus (AGPL-3.0), Healthchecks.io (BSD 3-Clause) and OneUptime (Apache 2.0).
Looking for a Healthchecks.io alternative?
For the reasoning behind checking from more than one region at all, see why a status page can show all green during a real outage. Comparing more than just this one alternative? The status page tool checklist covers what to test before committing to any of them.
