Teams choosing Uptime Monitoring Tools in June 2026 have to balance basic monitoring needs, status page fit, project health, shipping activity, licensing, and community signal. This section uses the supplied ToolVitals ranking data: health score, shipping score, ToolVitals score, GitHub stars, openness_label, license_label, and status for each listed tool.
The ranking is limited to open/source-visible tools and orders them by ToolVitals score first, with GitHub stars used only as a secondary popularity tie-breaker. The list should not be read as a pure popularity chart: smaller projects can rank highly when health and shipping signals are strong, while high-star projects can fall when current scores are weak.

Top 3 Highlights
Uptime Kuma ranks first with a 92 ToolVitals score, 94 health score, and 83 shipping score. Its status is 🟢 Excellent, making it the clear top-ranked option in this dataset.
Uptimekit ranks second with a 91 ToolVitals score, just one point behind Uptime Kuma. Its standout number is the 95 shipping score, the highest shipping score in the ranking, while its GitHub star count is much smaller at 72. It is listed as OSI-approved OSS under the MIT license and has 🟢 Excellent status, so its placement is driven by ToolVitals health and shipping signals rather than popularity.
Checkmate ranks third with an 88 ToolVitals score, 84 health score, and 87 shipping score. It is listed as OSI-approved OSS under the AGPL-3.0 license and has 10,039 GitHub stars, giving it both a strong ToolVitals score and a large community signal.
