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.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/counter-dev: open an issue to ask a question, or submit a pull request to add artifacts.
