OP3

- Open source and self-auditable

Watch-outs
- Not yet IAB-certified for ad buying
- No marketing demographics or attribution

Which one should you pick?
Pick CoHost if
You’re building around b2b podcasters. CoHost nails the niche nobody else owns — B2B analytics that tell you which companies your listeners actually work at. If you're running a thought-leadership podcast for sales pipeline, it's the closest thing to LinkedIn-style attribution for audio.
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.
