Adoption registry

Third parties that have built on Harpd data, verified by a human before listing. This is the one adoption count Harpd cannot inflate: every entry links to a real site usingreal Harpd data.

Quick answer

Who has adopted Harpd data?

No adoptions are verified yet — the registry starts empty by design, so it can never show a fabricated entry. Register yours at /developers/adopt/ and it appears here once confirmed. Harpd publishes 1,122 products as open CC BY 4.0 datasets; the registry tracks who genuinely reuses them.

Verified adopters

No adoptions verified yet.

The registry is populated only after a maintainer verifies a self-reported adoption, so it begins empty rather than with invented entries. Built something on Harpd? Register it and we'll list it once confirmed.

How an entry gets here

  1. A developer posts a self-report at /developers/adopt/ (or via /api/adoption-event). That logs an event only — it never appears here.
  2. A maintainer visits the submitted site, confirms it genuinely renders or serves Harpd data, and attributes Harpd.
  3. If legitimate, the entry is added to src/data/adoptions.json and appears on this page on the next deploy.

This verify-then-list rule is why the registry is trustworthy: it can only ever contain real, checked adoptions.
