# CSDN vs DNS测速

The clearest difference is ads: DNS测速 at none against CSDN's shown. CSDN's advantage is update cadence (weekly vs every 5 months) and chart position (#140 vs unranked). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

Both are free to download. CSDN sells 15 in-app purchases, starting at $12.99 per month and DNS测速 sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

CSDN ships an update weekly, DNS测速 every 5 months. The most recent releases landed on September 28, 2026 and September 14, 2026 respectively.
