I would not pick Cloudflare or CloudFront from a feature matrix. Both can make a site faster. The wrong one makes billing, purges, and security rules harder than they need to be.
Quick Answer
Choose Cloudflare if you want a CDN plus WAF and DNS in one place with less AWS ceremony. Choose Amazon CloudFront if your stack is already deep in AWS and you care more about IAM, S3 origins, and CloudWatch than a polished admin UI. Validate with one production-like property before you move traffic.
What I compare first
I start with four boring checks:
- Where the origin lives today
- Who will touch cache rules after launch
- How purge and rollback work under pressure
- Whether security rules need a separate product
If your site already sits on S3 or behind an ALB, CloudFront often wins on wiring. If you are tired of AWS console hopping and want DNS, CDN, and bot controls together, Cloudflare usually feels cleaner.
Cache and purge reality
CDN demos love TTFB screenshots. Operators care about bad deploys.
I ask: how fast can we purge a poisoned asset? How do we version hashed JS? Can a junior engineer undo a bad cache rule without paging the whole team? Cloudflare's dashboard is usually faster for that. CloudFront is fine if your team already automates invalidations in CI.
Pricing surprises
Both look cheap until you misconfigure origin fetch, image transforms, or high-churn APIs. I estimate:
- Bandwidth at expected peak
- Request volume for APIs and HTML
- WAF / bot / image costs as separate lines
Then I add 20% for "we will misconfigure something in month one."
When I refuse to switch
If the only reason is "everyone says Cloudflare is better," I wait. A CDN migration that breaks cookies, auth headers, or stale HTML is not a win. Run a shadow property, compare cache hit ratio for a week, then cut over.
