Which one should you pick?
Pick Castbox if
You’re building around global listening reach. Castbox is trying to be both a listening app and a creator monetization stack, which means it's a decent place to be discovered and a mediocre place to actually earn. Premium content gating works, but the buyer base is small.
Pick Podsync if
You’re building around . Podsync is the open-source tool for turning YouTube channels into RSS feeds, either self-hosted via Docker or through the free hosted instance. Useful for archiving video shows as audio-only feeds, but YouTube changes can break it without notice and the hosted instance hits rate limits.
