WebsitesHas

WebsitesHas is a hypothetical, open-source registry and API intended to catalog publicly accessible metadata about websites. It aims to provide a structured, extensible dataset describing domains, hosting regions, technologies, performance, and accessibility characteristics.

The project is designed to help developers, researchers, marketers, and auditors analyze web ecosystems, compare site configurations, and monitor trends in technology adoption across industries and regions.

Data are collected from multiple sources, including web crawlers, certificate transparency logs, public registries, performance monitors, and crowdsourced validation. Entries are versioned and timestamped, with automated quality checks and community reviews to improve reliability.

Governance is informal and international, coordinated by a volunteer community. The project emphasizes openness and accessibility; code and datasets are released under a permissive license to encourage reuse and independent verification.

Limitations include potential inaccuracies in automated data collection and the risk of misinterpretation of metrics. Privacy considerations are addressed by limiting data to publicly observable information and providing opt-out mechanisms and clear documentation.
