Monitoring & observability: star history compared

netdata/netdata

Observability is where open source beat the commercial incumbents in plain sight. Grafana and Prometheus grew into the default dashboard-and-metrics pair for a generation of infrastructure, Netdata took the single-node niche with zero-config appeal, and SigNoz and VictoriaMetrics are the newer curves betting on all-in-one tracing and raw efficiency respectively. The OpenTelemetry collector's rise tracks the whole industry converging on one wire format.

Frequently asked

Which of these monitoring & observability has the most GitHub stars?

netdata/netdata is the most-starred of the monitoring & observability gitdebt compares, with 80,535 GitHub stars as of Sep 2026. It earned its first star in 2013.

Which of these monitoring & observability is growing the fastest?

grafana/grafana added the most stars over the last 90 days of its cached history — about 108 new stars, compared with about 54 for the category leader netdata/netdata. 90-day figures are approximate for older repos, whose history is downsampled.

How is this comparison computed?

The table ranks public repository metadata by current total stars. Each curve is that repository's stored star series — read either from GitHub's stargazer list or rebuilt from historical star data — drawn on shared axes, with trailing 90-day growth estimated from it. The legend under the chart names each series' own source and coverage date. Repo-health charts come independently from each repository's commit history.
