Why choose ActiveState for your open source language runtimes


No more "works on my machine" issues. Each time you install an ActiveState runtime, it will be exactly the same. Every package and version is recorded in a complete history.


Keeping a consistent environment between team members has never been easier. Create an organization and if one member changes a runtime, everyone can pull the change down to stay in sync.

Easy to Distribute

We give you many ways to distribute your runtime. You can share a single command, set up an artifact repository, or generate an installer. It's perfect for large teams and open source projects working collaboratively.


We're on top of all vulnerabilities in your runtime. You'll see any vulnerabilities in your project in real-time and get alerts when new vulnerabilities are discovered.


Concerned about compliance? We make it easy to see all the licenses for your dependencies, so you're never at risk. Soon, we'll let you set policies to create organization-wide enforcement for compliance issues.


Our powerful graphQL API lets you integrate with your existing pipelines. Use the API to access licenses, vulnerabilities, and artifacts or to generate a complete SBOM (Software Bill of Materials). Beyond the API, you can also integrate with existing tools like JFrog Artifactory seamlessly.
