# Proxygen vs Stream HTTP Sniffer

The clearest difference is review sentiment: Proxygen at 83% against Stream HTTP Sniffer's 11%. Proxygen also leads on rating (4.3 vs 3.0) and chart position (#109 vs unranked). Stream HTTP Sniffer's advantage is update cadence (every 5 days vs every 2 weeks) and iOS requirement (13.0 vs 16.4). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Proxygen sells 4 in-app purchases, starting at $2.99 per month and Stream HTTP Sniffer sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

That said, the two scores are not equally well evidenced: Proxygen has 18 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 83% of Proxygen's written reviews are positive against 11% of Stream HTTP Sniffer's.
