Podcast Analytics for OP3

OP3 (Open Podcast Prefix Project) is a free, open-source podcast analytics service committed to open data and listener privacy. This plugin integrates OP3 with any WordPress podcast site in minutes.

What it does

• Automatic feed prefix — Adds https://op3.dev/e/ before every audio enclosure URL in your RSS feed. Works with PowerPress (Blubrry), Seriously Simple Podcasting, Podlove, and any plugin that generates a standard RSS2 podcast feed.
• Dashboard widget — Shows your podcast’s downloads for the last 7 days directly on the WordPress dashboard.
• Statistics page — A dedicated admin page with download counts per episode, switchable between last 24 hours, 7 days, and 30 days.

How the OP3 prefix works

OP3 is a transparent redirect service. When a listener downloads an episode:

1. Their app requests https://op3.dev/e/yoursite.com/episode.mp3
2. OP3 logs the download anonymously and immediately redirects to https://yoursite.com/episode.mp3
3. The audio file is served normally from your server

Your audio files are not modified or hosted anywhere else. Only the URL in the RSS feed changes. Listener privacy is protected — OP3 never stores raw IP addresses.

Why OP3?

• 100% free and open source — no subscription, no lock-in
• No signup required to start measuring — just add the prefix
• Open data — your stats are publicly accessible to anyone, including app developers
• Privacy-first — no raw IPs stored, no tracking pixels
• Every show automatically gets a free public stats page at op3.dev/show/{uuid}

Requirements

• A WordPress site with a podcast RSS feed
• A bearer token from op3.dev/api/keys for statistics (the feed prefix works without one)

Privacy Policy

This plugin sends data to the external service op3.dev in two ways:

1. Feed prefix — When a listener downloads a podcast episode, their request passes through op3.dev before reaching your audio file. OP3 logs anonymised request data (no raw IP addresses). See OP3 Privacy Policy.
2. Statistics API — When you view the Statistics page or Dashboard widget, the plugin makes an authenticated request to the OP3 API (op3.dev/api/1/) to retrieve download counts for your show. No user data from your WordPress site is sent to OP3.

No data is collected from your site’s visitors beyond what OP3 records as part of the redirect.
