How pricing works
These two tools don't price the same way, so the headline numbers below aren't directly comparable until you plug in your own volume.
- Cloudflare (Tiered) — Cloudflare bills on a fixed plan from $25/mo, so the listed price is what you pay regardless of volume.
- Datadog (Per Usage) — Datadog bills on usage — host on top of a paid plan starting at $18/mo. The plan includes an allowance; anything beyond it is metered.
Per-minute, per-credit and per-token rates exclude any downstream model, speech or telephony costs unless the vendor states otherwise.
Global CDN, edge compute, and security platform, publicly traded (NET), ~$50B market cap. Positioned as the alternative to AWS CloudFront + Akamai for developers who want simpler pricing and a stronger free tier. Distinctive for Workers (edge compute) and R2 (object storage) undercutting AWS S3 with zero egress fees. Free tier is genuinely production-grade for many projects. Priced $20/mo (Pro) to $200/mo (Business) plus per-usage overages.
The dominant cloud observability platform (metrics, logs, traces, APM), publicly traded (DDOG), ~$45B market cap. Positioned as the alternative to New Relic + Splunk + PagerDuty stitched together. Distinctive for its notorious usage-based pricing that has surprised engineering teams with 6-figure monthly bills (Coinbase's leaked contract was ~$65M/year in 2022). Priced by seat + host + volume across 20+ meters. Popular with engineering teams; feared by finance teams.

What each is best for
Cloudflare is worth it if… anyone running a website that wants free-tier DDoS protection + CDN + DNS — with Workers (edge compute) and R2 (S3-alternative storage) as paid upgrades if you go serverless. Free covers most personal + small-business sites; Pro adds WAF and page rules; Business adds prioritized routing and SSL flexibility; Enterprise custom.
Datadog is worth it if… infrastructure teams (10+ engineers) that need APM + logs + metrics + synthetics + RUM in one platform — the observability default at mid-market and enterprise scale. Infrastructure covers hosts; APM, Logs, RUM, Synthetics, Database Monitoring each priced separately per module.
Bottom line: Choose based on how you want to pay — Cloudflare is tiered, Datadog is per usage.
