Two open-source philosophies
Plausible and Matomo share the conviction that analytics data does not belong in someone else's cloud. After that, the paths split. Plausible reduces deliberately: one page of metrics, no user tracking, banner-free in return. Matomo builds out: segments, funnels, e-commerce, plugins.
Our own website runs on Plausible CE because the questions we ask of datascale.de are simple. In client projects with shop reporting we regularly recommend Matomo instead, or a warehouse setup outright. The per-tool breakdowns live on the tool pages.
The wider field, with GA4, Piwik PRO and etracker: GDPR-compliant analytics.
