Fathom Analytics is a privacy-first website analytics platform that provides GDPR-compliant, cookie-free analytics as an alternative to Google Analytics. The platform serves thousands of companies, including Fortune 100 enterprises and government agencies, offering simple and accurate traffic metrics without tracking personally identifiable information. Fathom exposes a REST API with base URL https://api.usefathom.com/v1, enabling developers to manage sites, events, and milestones, generate aggregated custom reports, and retrieve real-time visitor counts. Authentication is via Bearer token API keys, which are generated in the account settings area and support configurable permissions scoped to admin, all sites, or individual sites.
