Self-hosted web analytics puts the tracking script, the database and the reports on hosting you control, which is precisely why UK and EU organisations keep choosing it over Google Analytics. Matomo is the serious option, at version 5.13.0 in August 2026, and it brings the plugin ecosystem, the documentation and the import tools with it. Open Web Analytics is the quieter alternative, still shipping (1.12.0 in August 2026) and now asking for PHP 8.2 or newer, but with a much thinner ecosystem behind it.
The comparison set is Google Analytics 4, which costs nothing and sends your visitor data to Google; Plausible, from US$9 a month for 10,000 monthly pageviews; and Fathom, at US$45 a month for 500,000. Matomo will happily sell you a hosted version too, from around 29 euros a month with the data held in Frankfurt. Self-hosting the community edition swaps all of that for hosting plus your own maintenance, with no traffic ceiling written into a plan.
The regulatory history is the part people get wrong in both directions. Between January and June 2022 the Austrian, French and Italian data protection authorities each found that sending visitor data to Google in the United States broke the GDPR transfer rules after the Schrems II judgment. The EU-US Data Privacy Framework adequacy decision of July 2023 changed that transfer position, and Google is certified under it, so Google Analytics is not simply outlawed. What never changed is the separate question of cookie consent, and that is where self-hosting still earns its keep.
