Licensing, air-gapped environments, migrating from Kafka, and what you need to get started. Did not find your answer — write to us.
Yes, that is a core scenario: the image ships as an offline archive, the license is verified without internet access, and there is no built-in telemetry — nothing leaves your perimeter.
The version you bought keeps working forever. Renewal (≈25% per year) is only needed to receive new versions — the JetBrains model.
No. Roxa speaks the Kafka protocol: existing clients (kcat, Go, Python, C# and others built on librdkafka) connect as they are — only the broker address changes.
A Linux server with 2+ vCPUs and 4+ GB RAM, Docker and Docker Compose. No JVM, no ZooKeeper, no external database. Storage is your S3/MinIO or a local disk.
Only with you: in your object storage (S3/MinIO) or on the server’s file system. The product is self-hosted and sends nothing outside.
Today Roxa is a single node; reliability comes from S3 storage rather than replication: a node dies — a new one starts and reads the same data. An HA cluster is in development (the Enterprise edition).
An invoice paid by bank transfer in rubles; the license key arrives by email and works offline. Start with the free Community edition or write to us via the support form.
