Which one should you pick?
Pick Buffer if
You’re building around . Buffer is the cheap, clean social scheduler that podcasters reach for when they need to push clip exports from Opus Clip or Headliner across Instagram, X, LinkedIn, and TikTok without paying agency-tier prices. No direct host integration, analytics are lighter than Sprout, but the composer is the cleanest in the category.
Pick Castbox if
