The free tier Fraud Blocker doesn't have
Fraud Blocker is trial-only: a 7-day look, then billing from around $79/mo on the Standard plan. Didva's Watchtower plan is free forever — 3,000 clicks a month of detection across every ad channel, manual IP blocking and a weekly digest, with no credit card.
For a smaller advertiser, or for anyone who just wants a permanent second pair of eyes on their traffic, that is the whole decision: one tool costs nothing to keep running, the other starts a subscription the moment the trial ends.
Comparable detection, a lower price of entry
The two tools overlap a lot on the mechanics — real-time monitoring, device fingerprinting, VPN and proxy signals, customizable rules and CSV export of the offending IPs. That overlap is exactly why entry price matters: Didva's paid protection starts at $39/mo on Starter versus Fraud Blocker's $79/mo monthly on Standard, and both bill month-to-month with no contract.
If you were choosing on detection alone, it would be close. Once you factor in the free tier and the entry price, Didva is the cheaper way to get to the same class of protection.
Where each tool leans — pick by what you run
An honest comparison names the trade-offs. Fraud Blocker covers Facebook and Instagram today and ships API access on every plan, which is worth a lot if Meta is your main channel or you want to wire fraud data into your own stack now.
Didva covers Google and Bing today with Meta protection in rollout, reserves API access for the Agency plan, and leans into click-level evidence — per-IP reasons and appeal packs you can attach to a Google Ads invalid-click claim. If Google is your primary spend and refund evidence matters, Didva fits; if you live in Meta and need an API today, weigh that in Fraud Blocker's favour.
