Which one should you pick?
Pick Magellan AI if
You’re building around advertisers and agencies. Magellan AI is the closest thing to a Bloomberg terminal for podcast advertising — competitive intelligence, pixel attribution, and pod-to-pod reach data that brands actually use to plan seven-figure buys. Indies and small shows aren't the customer.
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.
