Truly different capabilities under the hood. Yes, they are both CDN providers, but fastly offers a remarkable amount of customization that cloudflare does not. For 99% of customers, one can argue that cloudflare is more than sufficient. For 1% of customers, fastly is arguably the correct choice just based on feature set alone. So, in summary, you can certainly compare the two, but for certain customers cloudflare lacks the feature set they may choose to use on fastly.
