Verdicts by reader
- Platform engineer
- If you already proxy through Cloudflare, its zone settings cover AI crawlers with no code. DataDome needs a server module plus a client tag.
- Security engineer
- DataDome scores each agent on identity strength and fraud history and blocks bad intent even when the agent is authenticated; Cloudflare focuses on identity and category.
- Publisher operations
- Cloudflare is the cheaper start for training opt-outs; DataDome is a paid bot and fraud stack with monetization partners.
What each does not do
Cloudflare
- BotBase does not block traffic itself; mitigation needs Security rules or AI traffic options (BotBase docs, updated 2026-10-08).
- Disallow AI Training cannot pass a no-training preference to Bing until Microsoft ships robots.txt support, targeted early 2027 (Cloudflare blog, 2026-09-15).
- Web Bot Auth verification does no nonce validation today; Cloudflare relies on short expires values (Web Bot Auth docs).
- Pay per crawl is not self-serve: the docs (updated 2026-07-28) tell site owners to reach out to Cloudflare to join the beta.
DataDome
- Agent Trust does not run on its own; Bot Protect must be fully installed with server and client components (Agentic Trust docs).
- Monetization is not in the Essentials plan; it starts at Advanced (pricing page).
- No published control that separates search crawling from training crawling as distinct purposes (docs and pricing read 2026-11-04).
