Quilt
Quilt DataQuilt is a scientific data management platform on AWS that packages data with metadata, documentation and version history for reuse. It ships a Python SDK and CLI for creating and installing versioned data packages on S3, and a self-deployed catalog stack (web UI, Lambda indexing services, and a search cluster) for browsing, searching and visualizing them.
quilt3 on PyPI is declared as the measurement identity, and the reasoning is recorded because the package is one of two components in this repository. Installing quilt3 gives you Quilt - the SDK and CLI in `api/python` create, version and install data packages against S3 on their own, with the catalog and Lambda stack in `catalog` and `lambdas` as an optional browsing layer over the same packages, all from the same Apache-2.0 source. Every programmatic use of Quilt goes through quilt3, so its downloads count Quilt users rather than clients of a separately shipped server, which is what separates it from weaviate-client or the openmldb SDK. The count is a lower bound (catalog-only users never install it) and the note says so.
Openness
4 high confidence- license
- Apache-2.0(OSI)

- core features withheld
- 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.

Adoption
2 medium confidenceQuilt'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.

Capability
4 medium confidenceQuilt 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.
