  • They diverge on capability: Cloudflare covers Global CDN, Memcached covers In-memory key-value cache.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Cloudflare

  • Free tier limited to basic features (no advanced analytics or premium features)
  • Pro tier ($20-25/month) caps at professional websites (higher tiers needed for enterprise scale)
  • Caches only anonymous API GET responses (authenticated requests and non-GET methods not cached)
  • Geographic coverage limited to announced 330+ cities (may not cover all regions globally)

Memcached

  • No persistence at all: restart a node and its cache is gone, which every design must assume
  • No replication or failover, so losing a node loses that share of the cache
  • Only simple key-value, with none of the lists, sorted sets or streams Redis offers
  • Values are capped at 1MB by default, which surprises teams caching large documents

Source
Memcached: Is Memcached free?

Yes, open source with no licence fee.

Cloudflare: How much does Cloudflare cost beyond the free tier?

Cloudflare uses pay-as-you-go pricing beyond free allocations, charging per million requests, per GB-month of storage, or per vCPU-second depending on the service.

Source
Memcached: Memcached or Redis?

Memcached is a pure cache: simpler, multithreaded and very predictable. Redis adds persistence, replication and rich data structures, which is why it is the default choice unless you specifically want a cache and nothing more.

Cloudflare: Does Cloudflare charge egress fees?

No, Cloudflare explicitly states no egress fees and no hidden costs; you only pay for the usage metrics specific to each service.

Source
Memcached: Does Memcached persist data?

No. Everything is in memory and lost on restart, by design.

Cloudflare: What's the Enterprise pricing model for Cloudflare?

Cloudflare Enterprise offers custom pricing and volume discounts available through direct sales for organizations with specialized needs and large-scale usage.
