ActiveState Library
79M+ Components
A single, trusted source for every open source component your organization touches, spanning 12 ecosystems.
Verified from source code to binary
Every component is built from original source code in SLSA Level 3 infrastructure, blocking malicious packages before they enter the catalog.
12 language ecosystems in one catalog
Your stack likely spans multiple languages, but most providers only cover one ecosystem, leaving the rest of your open source unmanaged. ActiveState covers Python, Java, JavaScript, Go, R, C, Rust, .NET, and more from a single source, including all transitive and OS-level dependencies.

FAQs
What is the ActiveState Library?
Over 79 million open source components spanning 12 language ecosystems, including all transitive and OS-level dependencies. The ActiveState Library contains packages, container images, and language runtimes and is the foundation behind every ActiveState product.
How is the ActiveState Library different from PyPI, npm, or DockerHub?
Public registries distribute pre-compiled binaries with no guarantee of integrity. ActiveState builds every component from source, blocks known malicious packages, and provides full provenance.
Which ActiveState product is right for my team?
Our Curated Catalog is for teams that want individual packages through existing tools. Secure Containers are for containerized deployments. Managed Distributions are for teams that need complete, managed language environments.
What compliance standards does ActiveState support?
Every component ships with full provenance, signed SBOMs, and license metadata, supporting FedRAMP, SOC 2, and other software supply chain transparency frameworks.
