yes — installing the Quilt catalog stack requires a license key or an active Quilt Business subscription on AWS Marketplace, deployed from Quilt-provided CloudFormation templates

A single Apache-2.0 LICENSE covers the whole repository: the Python SDK, the web catalog frontend and the Lambda backend services. The full Quilt platform is a different matter. The catalog installation guide requires a license key or an active Quilt Business subscription on AWS Marketplace, and deploys from Quilt-provided CloudFormation templates. A license-keyed tier beside the open repository makes this open core.

Quilt's adoption reading comes from PyPI downloads of `quilt3`, the SDK and CLI that creates, versions and installs Quilt packages against S3 without needing a deployed catalog, so the count reflects Quilt users directly rather than clients of a separate server. It undercounts people who only browse a deployed catalog without installing the package, which is why confidence is medium, though GitHub stars independently point to the same range.

Quilt provisions its own search cluster and indexing Lambdas as part of its deployed stack, so it versions data it also indexes and serves itself rather than only versioning storage it does not index. It hosts no ranking or embedding model inside the query path, which is why it sits one step behind Vespa at the top of the category.

  Catalog Installation Guide: the catalog runs as a CloudFormation stack, the Terraform path "first provisions the foundational infrastructure (VPC, database, search cluster)", and running it needs working knowledge of CloudFormation, S3 and Elasticsearch Service.
