Counter

Counter (counter.dev) is an open-source, privacy-friendly web analytics service. A lightweight tracking snippet POSTs a single aggregated hit per visit to a public collect endpoint (t.counter.dev), and a token-authenticated dashboard data feed returns aggregated stats. Counter uses no cookies, no logging, and no IP fingerprinting. It is AGPL-3.0 licensed and can be self-hosted; the hosted service is pay-what-you-want.

Counter publishes 3 APIs on the APIs.io network: Account API, Stats API, and Tracking API. Tagged areas include Web Analytics, Privacy, Open-Source, Tracking, and Self-Hosted.

The Counter catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Counter’s developer surface includes authentication, documentation, engineering blog, sandbox, CLI, getting-started guide, support, and 22 more developer resources.
