Free to run. Licensed to rely on.
Every tier is the same full product: no license server, no telemetry, no call-home, no throttling. Nothing is metered at runtime, because the engine has no network peer and cannot count your fleet. Personal, non-commercial and evaluation use is free. Pick a commercial tier by company size or instance count, whichever you cross first.

What a license key actually does
It silences one notice line at startup. That is the entire effect. Every tier is the same binary at full capacity: nothing gated, nothing capped, nothing phoning home. The key is a signed claim checked offline, so it works air-gapped and on a machine with no egress.
Keys are annual. An expired key nags and keeps running: a renewal stuck in procurement should not be an outage, and a missing key never stops a pipeline. The band you sit in is a statement you make at purchase and revisit at renewal.
Billed annually, in your own currency at checkout.
What the cluster costs you in cash
Confluent Cloud for Apache Flink publishes $0.21 per CFU-hour. A statement consumes at least one unit, and a stateful windowed job usually more. One unit running continuously for a year is $1 840, the documented floor. That is stream-processing compute alone, before the Kafka cluster and before data transfer.
Three modest continuous jobs at that floor is roughly $5 500 a year and climbs with every window you add. Self-managing Flink instead moves the cost from an invoice to a salary line.
Ubik Team is $1,200/yr for up to ten production instances, on machines you already have, with no metered compute and nothing to scale up under load. There is no per-job cost, because there is no control plane charging for one.
We are not claiming your bill. We are pointing at a published rate and showing the division, so you can run it against your own usage. If you are paying for stream-processing compute today, that number is on an invoice you already have.
Rate as published by the vendor, A statement consumes at least one CFU and a stateful windowed job usually consumes more, so this is the documented floor. Flink compute only: the Kafka cluster and data transfer are billed separately.
