RealUptime Monitor vs OneUptime
OneUptime bundles uptime monitoring, status pages, incident management, on-call, logs, metrics, traces, and error tracking into a single Apache-2.0-licensed platform you can self-host free or use hosted with metered add-ons. RealUptime deliberately does less: monitoring, status pages, error tracking, and public outage data, each flat-priced. This page compares the two honestly, sourced to OneUptime's own pricing page and repository.

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.
OneUptime: 1 status page and 100 subscribers free, with active monitors billed at $1/monitor/mo even on the free plan.
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.
OneUptime: Apache 2.0 licensed; self-hosting from GitHub is free.
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 an OneUptime 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.
