Real-time compute

Serve fresh, complex features in under 5ms—without complicated streams.

Fresh data from any source

Fetch features directly from APIs, databases, and live systems at inference time – Chalk is data source agnostic.

Fast iteration in Python

Define features once in Python and let Chalk handle orchestration.

Unified online + offline serving

Train, test, and serve models using consistent features with point-in-time correctness, all from one platform.

Observability and lineage

Trace every feature computation from any run with time travel, drift detection, and telemetry.

Deploy in your cloud

Run in your VPC. Integrate with your existing data stores and infrastructure.

Chalk is a real-time compute engine with a  built-in feature store, designed for serving ML and GenAI features.
