Which one should you pick?

Pick OP3 if

You’re building around privacy-minded podcasters. OP3 is the rare analytics tool you can actually inspect — open source, single-cloud, no shadowy data deals — and it's free forever for any podcaster who adds the prefix to their feed. The trade-off is no IAB certification yet, so big sponsors may still ask for Podtrac numbers alongside it.

Pick Voxalyze if

You’re building around growth-focused publishers. Voxalyze invented Podcast Visibility Optimization — essentially SEO for Apple Podcasts and Spotify search — and the visibility module is genuinely the strongest in that niche. It's pricey, opaque about pricing, and not what you want if you mostly need download or attribution data.
