Enterprise Build Solutions

The ActiveState Platform automates the tools we’ve been using for 20+ years to build our open source language distributions. But languages, operating systems, packages and dependencies continually change, resulting in a combinatorially complex problem. ActiveState experts can:

  • Ensure your builds can be built, and with your specific options.
  • Provide security and compliance reports for your builds.
  • Help you understand your build’s OEM and indemnification options.
