# Castream vs RTMP Broadcaster

The clearest difference is review sentiment: Castream at 100% against RTMP Broadcaster's 57%. Castream also leads on update cadence (every 4 days vs every 3 weeks) and rating (5.0 vs 4.7). RTMP Broadcaster's advantage is ratings volume (30 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Castream sells 4 in-app purchases, starting at $12.99 per month and RTMP Broadcaster sells 3 in-app purchases, starting at $12.99 per 7 days. Whichever you choose, the download price is not the number that matters.
