Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Redis
- Licensing changed from BSD to AGPL in 2025, impacting open-source usage
- All data must fit in memory, limiting scalability to available RAM
- No built-in support for multi-tenancy
- Limited transaction support compared to traditional databases
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
Redis: Is Redis open source?
Redis was open source under the BSD license since its inception in 2009 and has remained open source. However, in 2024-2025, Redis Labs changed licensing to source-available and AGPL, prompting the creation of Valkey, a BSD-licensed open-source fork.
SourceYarn: 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.
SourceRedis: What is Redis used for?
Redis is an in-memory data structure store used primarily as a cache, database, and message broker. It provides high-speed data access for real-time applications, sessions, leaderboards, real-time analytics, and other use cases requiring fast data retrieval.
SourceYarn: Can I use Yarn in offline environments?
Yes, Yarn supports secure offline environments. The yarn.lock file enables reproducible installs without requiring new downloads.
