What is Webbkoll?
Webbkoll is an open-source tool from the Swedish privacy association Dataskydd.net. It automatically analyses the privacy practices of any website: which external resources are loaded, which trackers are embedded, which data flows to third parties. The results appear as a detailed report, with no registration required. Enter the URL, start the analysis, read the report.
Core features
- Tracker detection: Webbkoll identifies embedded analytics services and tracking scripts, showing which of them become active when a page is loaded.
- Analysis of external requests: The tool lists all third-party connections a page establishes when loading, including the respective domains.
- Quick privacy check: Before launching a web project, you can quickly check whether unintended data flows exist.
- No authentication required: Access is fully open, without an account or API key.
- Open-source codebase: The source code is publicly available and can be self-hosted.
Who is Webbkoll for?
Data protection officers use Webbkoll to quickly check external or internal websites for obvious privacy issues. Developers use it before go-live to check whether embedded libraries generate unwanted external requests. The tool is also useful in training: the report makes abstract concepts such as third-party tracking concretely visible for beginners.
The limitations are clear. Webbkoll analyses a single page load and captures only what happens during the initial loading process. Trackers that become active only after user interaction or login remain invisible. For in-depth technical audits, such as complete GDPR documentation, it is not sufficient.
Context & alternatives
Webbkoll belongs to the category of passive web inspection tools. It runs entirely in the browser and does not interact with the website being analysed. Browser extensions such as uBlock Origin (with its statistics view) and the EFF tool Privacy Badger follow comparable approaches, though they work locally in the user's own browser and do not offer URL-based remote analysis. For those who need structured reports on external domains without installing a browser plugin, Webbkoll offers a more direct route. The key advantage over commercial scanning services: the codebase is public, and anyone can run their own instance.
