OP3
OP3 is a free, open-source podcast prefix analytics service for podcasters and podcast hosting companies. To measure downloads, a host or podcaster places https://op3.dev/e/ before episode URLs in a podcast feed. Each measured show receives a public statistics page with download metrics, detailed breakdowns, and spreadsheet exports covering its history. OP3 also provides an API for collected podcast data; requests require a bearer token linked to a valid API key. The service says it stores basic request attributes, hashes and encrypts listener IP addresses before storage, and does not combine those addresses with third-party data or services. Its privacy policy says no cookies are used and identifies Cloudflare as the sole hosting provider and data store. OP3 says its redirect service uses a global CDN with edge nodes in more than 335 cities across more than 125 countries. API hit-query filtering by URL or hashed IP is limited to the last 90 days.
