Vemetric is a hosted web and product analytics service from seriouscode GmbH in Austria. Next to the usual traffic reports, it records custom events, links earlier anonymous activity to signed-in users once you identify them, and shows each user’s journey. One project can cover several sites, such as a landing page and the web app behind it.
The event limit is shared by all projects in an organization. The free plan has two projects, two seats and one month of data, while Professional removes the project and seat limits and keeps data for five years. The vendor labels the current prices as early pricing.
The code is open source under AGPL-3.0, but there is no official self-hosted version yet.
Create a project, then paste the Vemetric snippet into the head of your pages with your project token in the data-token attribute; the token is in the project settings. Page views and outbound link clicks are recorded automatically, localhost traffic is ignored unless you allow it, and custom events can be sent with data-vmtrc attributes on HTML elements.
There are also a JavaScript SDK, a Google Tag Manager guide, SDKs for Astro and React, and backend SDKs for Node.js, PHP, Python and Go. On WordPress, install the Vemetric plugin from Plugins > Add Plugin and enter the token under Settings > Vemetric. There is no self-hosted installation yet.
As documented on the vendor’s own pages. “Partly” means the feature has limits or is only on some plans.
What the vendor documents. A platform that is not listed has no guide, plugin or package from the vendor.
No, not by default. The vendor says anonymous visitors are recognized with a hash that uses a daily rotating salt, and that cookies can be switched on as an opt-in once you have your users’ consent. Whether you need a banner depends on your setup and on the rules that apply to your site.
Tracking continues. The limit covers all projects in your organization, and the vendor says you lose access to the dashboard if you exceed it multiple times, so upgrade in time. If the overage comes from a DDoS attack, the vendor asks you to get in touch and says it will not charge for those events.
Yes. The Free plan includes 2,500 events a month, two projects, two seats and one month of data retention. Professional is sized by monthly events, has unlimited projects and seats and five years of retention, and can be billed monthly or yearly.
Not yet. The code is open source under AGPL-3.0, but the vendor offers only the hosted service, with servers in the EU. Its FAQ says a self-hostable Community Edition is in the works, and the repository notes that it will cover web analytics and user journeys.
