Streambased

Streambased unifies Apache Kafka and Apache Iceberg into a single queryable view, making real-time streaming data and historical table data accessible together without copying data, building new pipelines, or changing existing tools. Its zero-copy architecture turns live Kafka topics into Iceberg tables queryable with SQL in milliseconds, while metadata, schema rules, and access controls carry over from Kafka to Iceberg for unified governance. The platform ships as Streambased Cloud (managed) and the Streambased Platform components I.S.K. (Iceberg Service for Kafka), K.S.I. (Kafka Service for Iceberg), Hyperstream, and Slipstream, and is consumed through the Apache Iceberg REST catalog interface and native Apache Kafka protocol using per-cluster API keys. Backed by Seedcamp.

Streambased is profiled on the APIs.io network. Tagged areas include Company, Data, Streaming, Apache Kafka, and Apache Iceberg.

Streambased’s developer surface includes documentation, getting-started guide, engineering blog, pricing, signup flow, support, YouTube channel, and 12 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/streambased: open an issue to ask a question, or submit a pull request to add artifacts.
