Offen is open-source analytics where visitors opt in and can see their own data. It's free, but there's no hosted service: you install it with Docker or another route in the docs. Anyone who declines the banner isn't counted at all. - **Value for money: C.** Free software, but only if you host it yourself, which needs a server. There's no paid hosted plan to compare. - **Free plan and trial: B.** Nothing to pay and no page-view cap on record, though you carry the hosting cost yourself. - **Features: C.** Consent banner, operator metrics, multiple sites and teams, encryption and retention. Opt-in means declined visitors don't show up, so the numbers run low by design. - **Ease of use: D.** No rating on record and it needs self-hosting with Docker, Ubuntu or Heroku, which is a command line job. - **Platforms and integrations: C.** Web only, with no integrations listed. The interface comes in English, French, German, Portuguese, Spanish and Vietnamese. These are ToolGPA's own grades.

And it is not the kind of software a weekend replaces. That makes this kind of software worth paying for, not this one in particular: 41 of the 58 other website and product analytics tools grade higher. - You could not: A tracking script and a database that counts every visit. - You could not: End-to-end encryption done properly. - You could not: Sharing with other people, which means accounts and invitations.
