The short version

  • Yarn is a package manager.
  • Both are free.
  • Where Memcached falls short: no persistence at all: restart a node and its cache is gone, which every design must assume.
  • Where Yarn falls short: Yarn 2+ (Berry) has limited ESM support which can be a constraint for some projects.
  • Prices and features on this page 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

Yarn

  • Yarn 2+ (Berry) has limited ESM support which can be a constraint for some projects
  • Smaller ecosystem and community compared to npm, though still substantial

Answered from the vendors’ own pages

Memcached: Is Memcached free?

Yes, open source with no licence fee.

Yarn: What is Yarn's main advantage over npm?

Yarn downloads packages in parallel, significantly reducing installation time. It uses a yarn.lock file for deterministic installs, ensuring identical package versions across machines and preventing version conflicts common with npm.

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.

Yarn: Can I use Yarn in offline environments?

Yes, Yarn supports secure offline environments. The yarn.lock file enables reproducible installs without requiring new downloads.

Source
Memcached: Does Memcached persist data?

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