When to pick Arenadata / Corax
Large enterprise: multi-node clusters under heavy load, an immediate Russian software registry requirement, vendor support with SLA and turnkey rollout, and a budget to match.
Arenadata Streaming and Platform V Corax are serious enterprise Kafka distributions for large IT: clusters, rollout projects, an annual subscription. Roxa plays in a different league — where you need a reliable broker without a million-ruble budget and a support crew.
| Roxa | Arenadata Streaming | |
|---|---|---|
| What is inside | An original diskless broker (Rust), Kafka protocol | An Apache Kafka distribution (+NiFi etc.) |
| Payment model | Perpetual license + a year of updates included | Annual subscription (license + support) |
| Price range | Community — free; Pro — 150,000 ₽ per installation | On the order of a million ₽/year and up |
| Deployment | One container / docker compose, minutes | A cluster rollout, often a project |
| Operations | No dedicated team required | Requires Kafka cluster expertise |
| HA cluster | In development (reliability via S3 today) | Yes, standard Kafka replication |

| Target customer | Teams and mid-size business | Large enterprise |
The price reference is public: the entry edition of Arenadata Streaming (Lite, up to 32 cores) costs 990,000 ₽ per year — every year. A perpetual Roxa Pro license is 150,000 ₽ — less than two months of that subscription; after that you pay only for updates, and only if you need them.
Large enterprise: multi-node clusters under heavy load, an immediate Russian software registry requirement, vendor support with SLA and turnkey rollout, and a budget to match.
You need a reliable Kafka-compatible broker on-prem without a cluster or a subscription: data in your S3, deployment in minutes, a perpetual license. When you grow into HA — the Enterprise edition is in development.
