Uptime monitoring tools have to do two jobs well: detect problems quickly and give teams enough confidence that the project behind the tool is still healthy. For May 2026, this ToolVitals view compares 30 uptime monitoring, status page, and related reliability tools using the supplied health score, shipping score, GitHub stars, ToolVitals score, and status rating.
The ranking is ordered by ToolVitals score first, with GitHub stars used as a secondary popularity signal when scores are tied. That means a smaller project with strong health and shipping signals can rank above a larger project if its overall ToolVitals score is higher.

Top 3 Highlights
Uptime Kuma ranks first with a ToolVitals score of 93, the highest score in the set. It also has the largest GitHub footprint by a wide margin at 86,450 stars, alongside a 97 health score and 88 shipping score. Among the tools listed here, it is the clearest combination of broad adoption and strong current project signals.
Uptimekit ranks second with a ToolVitals score of 90 and the highest possible shipping score of 100. Its GitHub star count is modest at 42, so this ranking is driven more by the supplied health and shipping data than by popularity. The description points to admin dashboards and public status pages, which makes it a focused fit for teams looking at status-page-oriented uptime tooling.
Uni Status also scores 90 overall and has a 100 shipping score, placing it third after the GitHub-star tie-breaker. Its 4 GitHub stars make it a much smaller project than Uptimekit, but the supplied scores still put it in the Excellent group. Based on the description, it is positioned as an open-source uptime monitoring and status page platform.
