Is Valkey or Vitess better?

Neither clearly leads. Valkey starts at Free and Vitess at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.

Which is cheaper, Valkey or Vitess?

Valkey starts at Free and Vitess at Free.

Does Valkey or Vitess run on more platforms?

Valkey runs on Linux, macOS, Docker, Self-hosted. Vitess runs on Linux, macOS, Docker, Kubernetes.

Can I use Valkey for free?

Both have a free tier, so you can try either at no cost before committing.

What is Valkey best used for?

Valkey is most often used for continuing on a permissively licensed in-memory store after the redis licence change, caching and session storage where a foundation-governed project is a procurement requirement, migrating from redis without rewriting application code. Of those, continuing on a permissively licensed in-memory store after the redis licence change and caching and session storage where a foundation-governed project is a procurement requirement are not what Vitess is typically brought in for.

What can Valkey do that Vitess cannot?

Valkey covers Redis-compatible, BSD licensed, Rich data structures, Replication and persistence. Vitess covers Horizontal Sharding, Connection Pooling, Query Routing, Online Schema Changes.

The short version

Each has a real cost: Valkey younger project, so its track record is short even though the codebase is not; Vitess vTGate scatter queries without sharding key incur significant performance penalties
They diverge on capability: Valkey covers Redis-compatible, Vitess covers Horizontal Sharding.

Where each one falls short

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

Valkey

Younger project, so its track record is short even though the codebase is not
Divergence from Redis grows over time, so compatibility is strongest near the fork point and weakens as both evolve
Ecosystem tooling and documentation still frequently assume Redis, leaving translation work

Vitess

VTGate scatter queries without sharding key incur significant performance penalties
Foreign key constraints not enforced across shards, requiring application-level integrity handling
Single primary per keyspace limits multi-region write capabilities
Distributed transactions without proper sharding key routing suffer performance degradation

Answered from the vendors’ own pages

Valkey: Is Valkey free?

Yes, BSD-licensed open source under the Linux Foundation.

Vitess: Is Vitess free to use?

Yes. Vitess is completely free and open source under the Apache 2.0 license. It is a graduated CNCF project with no licensing costs or pricing tiers.

Source

Valkey: Why does Valkey exist?

Redis changed its licence away from BSD in 2024. Valkey is the community fork continuing under permissive terms, backed by AWS, Google Cloud and Oracle among others.

Vitess: What databases does Vitess support?

Vitess supports MySQL and MariaDB as backend databases. It acts as a middleware layer that adds sharding and orchestration capabilities on top of these databases.

Source

Valkey: Can I switch from Redis to Valkey?

At the fork point it is drop-in compatible with existing clients and data. The further both projects move from that point, the more you should verify the specific features you use.

Vitess: Does Vitess require Kubernetes to run?

No. Vitess can run on Kubernetes using the Vitess Operator, but it can also be deployed on traditional infrastructure. Kubernetes integration is optional and provides additional automation benefits.

Source

Vitess: How does Vitess handle cross-shard transactions?

Vitess supports distributed transactions across shards, but they require queries to be routed through the sharding key. Transactions without a proper sharding key can result in slower performance.

Source

Vitess: Does Vitess enforce foreign key constraints?

Vitess does not enforce foreign key constraints across shards by default. Referential integrity must be managed at the application layer, though per-database support can be enabled with limitations.
