The short version
- Each has a real cost: Apache Kafka operationally heavy to self-host: brokers, storage, rebalancing and upgrades are a standing job, which is why managed Kafka is a large market; Cockroach Labs basic and Standard tiers limited to AWS and GCP (select regions only)
- They diverge on capability: Apache Kafka covers Durable commit log, Cockroach Labs covers Distributed SQL.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Apache Kafka
- Operationally heavy to self-host: brokers, storage, rebalancing and upgrades are a standing job, which is why managed Kafka is a large market
- Overkill for straightforward job queues, where a simpler broker is easier to run and reason about
- Ordering guarantees hold per partition, not per topic, and getting partitioning wrong is a common and expensive design mistake
- The ecosystem is fragmented across the Apache project and vendor distributions, so documentation and tooling advice often assume a particular distribution
Cockroach Labs
- Basic and Standard tiers limited to AWS and GCP (select regions only)
- Azure support restricted to Advanced tier only
- Basic tier limited to 50 million RUs and 10 GiB storage per month
- Advanced tier starts at $0.60/hour for 4 vCPUs minimum
- 3 TiB maximum storage on Basic and Standard tiers, 10 TiB per node on Advanced

- Can I use Apache Kafka for free?
- Both have a free tier, so you can try either at no cost before committing.
- What is Apache Kafka best used for?
- Apache Kafka is most often used for moving events between services without point-to-point coupling, feeding analytics and warehouses from operational systems in near real time, replaying history to rebuild state after a consumer bug, buffering bursty producers ahead of slower downstream systems. Of those, moving events between services without point-to-point coupling and feeding analytics and warehouses from operational systems in near real time are not what Cockroach Labs is typically brought in for.

Answered from the vendors’ own pages
Apache Kafka: Is Apache Kafka free?
Yes. Kafka is open source under the Apache License v2 with no licence fee. Costs come from the infrastructure you run it on, or from a managed service such as Confluent Cloud.
Cockroach Labs: What does the free Basic tier include?
The Basic tier is free and includes 50 million RUs and 10 GiB storage per month, with a maximum compute of 30K RU/sec. No credit card is required to start.
SourceApache Kafka: How is Kafka different from a message queue?
A queue usually removes a message once it is consumed. Kafka keeps an ordered, durable log, so consumers track their own position and history can be replayed — which is what makes rebuilding state after a bug possible.
Cockroach Labs: How much do the paid tiers cost?
Standard tier starts at $0.18 per hour for 2 vCPUs, and Advanced tier starts at $0.60 per hour for 4 vCPUs. Both tiers support additional resources with higher costs for increased compute and storage.
SourceApache Kafka: Who uses Kafka?
The project reports use by more than 80% of the Fortune 100, with over 5 million lifetime downloads.
Cockroach Labs: What are the storage limits for each tier?
Basic plan supports up to 3 TiB storage, Standard tier up to 3 TiB, and Advanced tier up to 10 TiB per node with unlimited total storage.
SourceApache Kafka: Do I need to run Kafka myself?
No. Self-hosting is the operationally expensive option; managed services such as Confluent Cloud run the brokers for you and bill on throughput and storage instead.
Cockroach Labs: Can I get trial credits before paying?
Yes, new users can try CockroachDB free with $400 in credits. The Basic and Standard plans do not require a credit card to start.
SourceCockroach Labs: Do legacy contracts have different pricing?
Customers with annual or multi-year contracts entered before December 1, 2024 can view legacy pricing terms on a separate page, which apply until their contract renewal date.
