The short version

  • Each has a real cost: Memcached no persistence at all: restart a node and its cache is gone, which every design must assume; Traefik no transparent pricing displayed for Traefik Hub API Gateway or API Management products
  • They diverge on capability: Memcached covers In-memory key-value cache, Traefik covers API Gateway.
  • 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.

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

Traefik

  • No transparent pricing displayed for Traefik Hub API Gateway or API Management products
  • No subscription period specified for paid tiers
  • Traefik Hub products require contacting sales for pricing

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.

Traefik: What pricing model does Traefik use for its paid products?

Traefik Hub products (API Gateway and API Management) use quote-based pricing. Specific rates are not published on the pricing page; you must contact sales to request pricing.

Source
Memcached: Does Memcached persist data?

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