We chose Apache 2.0 for the Spice OSS runtime.

TL;DR: Data-plane Apache 2.0, control-plane BSL.

Being such a core component, we want developers to be completely comfortable integrating and deploying the Spice runtime in their applications and services, as well as running Spice in their own infrastructure.

In addition, Spice OSS is built on other great open-source projects like DataFusion and Arrow, both Apache 2.0, and DuckDB (MIT), so being permissively licensed aligns with the fundamental technologies and communities it's built upon.

We expect to release specific enterprise control-plane services, such as our Kubernetes Operator under a license such as BSL.
