Hi Senol,
IBM BAMOE 9.3 Open Edition is free to download and use without a commercial license. You can download it from GitHub or IBM Fix Central
The GitHub repository provides source code and community resources, while Fix Central hosts pre-built, tested binaries for enterprise use.
Deployment is container-first, and that is the recommended approach.
The larger package size on Fix Central is due to bundled dependencies and components for a complete, production-ready installation.
