Confluent alternative — FAQ

Is Infinity Stream trying to replace Confluent at scale?
No. Confluent runs Kafka at enormous scale with a full enterprise ecosystem. Infinity Stream targets simpler, self-contained streaming and search use cases where a lighter runtime beats operating or paying for a full Kafka platform.
Is Infinity Stream free?
Yes — open source under Apache-2.0 and free to self-host. There is no throughput-based billing; your cost is your own infrastructure.
What is the status of Infinity Stream?
It is in active development. Evaluate throughput, durability and ecosystem needs against Confluent/Kafka before choosing it for critical pipelines.
