The short version

  • Only Memcached has a free tier, so it costs nothing to try first.
  • Each has a real cost: Memcached no persistence at all: restart a node and its cache is gone, which every design must assume; WarpBuild per-minute pricing requires tracking usage to estimate monthly costs
  • They diverge on capability: Memcached covers In-memory key-value cache, WarpBuild covers Optimized runner infrastructure.
  • 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

WarpBuild

  • Per-minute pricing requires tracking usage to estimate monthly costs
  • Large configuration runners (32 vCPU) expensive at $0.064/min
  • macOS M4 Pro 12-core at $0.16/min is highest-cost option
  • BYOC option requires cloud setup by customer

Answered from the vendors’ own pages

Memcached: Is Memcached free?

Yes, open source with no licence fee.

WarpBuild: How much cheaper is WarpBuild compared to GitHub Actions?

WarpBuild offers approximately 50% cost savings compared to GitHub-hosted runners. For example, Linux x86-64 2vCPU/8GB costs $0.004/min with WarpBuild vs $0.008/min with GitHub Actions.

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.

WarpBuild: What is BYOC and how does it differ from managed runners?

BYOC (Bring Your Own Cloud) allows customers to run WarpBuild on their own cloud infrastructure at $0.002/min. Managed runners use WarpBuild's cloud infrastructure. BYOC provides lower costs but requires customer setup.

Source
Memcached: Does Memcached persist data?

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

WarpBuild: Does WarpBuild support ARM64 runners?

Yes, WarpBuild offers ARM64 runners at lower costs than x86-64. Linux ARM64 starts at $0.003/min for 2vCPU/8GB configuration.
