Frequently Asked Questions
Which is the cheapest to start, Libsyn, Simplecast, or Transistor?
Libsyn has the lowest advertised entry price at 5 dollars a month for its Basic Audio plan, though that tier includes only about 3 hours of new uploads a month. Simplecast starts at 15 dollars a month and Transistor starts at 19 dollars a month, both with unlimited storage from the first tier.
Which platform keeps a show's older episodes hosted the longest?
Libsyn guarantees back-catalog episodes stay hosted forever on every plan regardless of upload tier, a structural policy dating back to its 2004 founding. Simplecast and Transistor both offer unlimited storage on their standard plans as well, so all three avoid forcing shows to delete old episodes.
Which tool offers the most built-in advertising revenue options?
Libsyn's AdvertiseCast subsidiary and Simplecast's AdsWizz-powered Podcast Marketplace both connect eligible shows with sponsors and support dynamic ad insertion. Transistor documents fewer native monetization tools by comparison.
Is any of these three a good fit for a podcast network with multiple shows?
Transistor and Libsyn are both built for multi-show management, Transistor through unlimited podcasts on every plan and Libsyn through network-level RSS feeds and enterprise tooling. Simplecast's plans are structured more around team seats on a smaller number of shows.
Do all three provide IAB-certified analytics?
Libsyn and Transistor both explicitly document IAB-certified download measurement, which matters for shows reporting audience numbers to advertisers. Simplecast advertises detailed listener analytics but does not document IAB certification specifically.
