The short version
- Only Vitess has a free tier, so it costs nothing to try first.
- Each has a real cost: Chroma chroma Cloud meters four separate dimensions: $2.50 per GiB written, $0.33 per GiB stored monthly, $0.0075 per TiB queried, and $0.09 per GiB returned over the network, as of August 2026.; Vitess vTGate scatter queries without sharding key incur significant performance penalties

Answered from the vendors’ own pages
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.
SourceVitess: 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.
SourceVitess: 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.
SourceVitess: 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.
SourceVitess: 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.
