System Requirements

Minimum:

Free WebFlow

1 GB RAM (normal workflow activity when using it for WebProof proofing production: 20 MB RAM and 0-5% CPU usage; high workflow activity: 50-100 MB RAM and 0-20% CPU). WebFlow consumes 0% CPU when idle.
CPU: 2 cores
WebFlow requires a maximum of 100 MB and 50-100 GB of additional space for production files.
Windows XP, 7, 8 or 10 and Windows Server 2003 R2, 2008 R2, 2012, 2016 or 2019.

Low-to-medium volume:

Platinum version with small peak production, few users, and few InDesign Correction users

Minimum 4 GB RAM (normal workflow activity when using it for WebProof proofing production: 20 MB RAM and 0-5% CPU usage; high workflow activity: 50-100 MB RAM and 0-20% CPU). WebFlow consumes 0% CPU when idle.
CPU: Focus on a few high-speed cores at normal production
WebFlow requires a maximum of 100 MB and 50-100 GB of additional space for other application and production files.
Minimum of 512 Kbit bandwidth (this is important for end users' InDesign Correction response times)
Windows 2008 R2 (64 bit), 2012, 2016 or 2019 (note that system requirements to newer InDesign Server versions can be higher than WebFlow minimum requirements).
InDesign Server up to version 2020.

Medium-to-high volume:

Platinum version with high peak production, many users, and many InDesign Correction users

Minimum 8 GB RAM (normal workflow activity when using it for WebProof proofing production: 20MB RAM and 0-5% CPU usage; high workflow activity: 50-100 MB RAM and 0-20% CPU). WebFlow consumes 0% CPU when idle.
CPU: Focus on many high-speed cores
WebFlow requires a maximum of 100 MB and 100-200 GB additional space for other application and production files.
Minimum 512 Kbit bandwidth (this is important for end users' InDesign Correction response times)
Windows 2008 R2 (64 bit), 2012, 2016 or 2019 (note that system requirements to newer InDesign Server versions can be higher than WebFlow minimum requirements).
InDesign Server up to version 2020.
