Pros & Cons
Drawpile
Pros
Completely free and open source under the GPLv3 license
Genuine real-time multi-user drawing with no per-seat cost or account requirement
Available on Windows, macOS, Linux, Android, and via a browser-based version
Governed by a non-profit structure explicitly designed to keep the software public and free permanently
Cons
Development is driven by a small team, so feature velocity can be slower than well-funded commercial tools
Lacks some advanced digital-painting features found in dedicated commercial apps like Photoshop or Clip Studio Paint
Real-time collaboration performance depends on the server used, whether self-hosted or a community server
Animation tools are described as rudimentary rather than a full animation production suite
SOGo
Pros
Free and open source with no per-user licensing cost for the core server
Broad native client support through CalDAV, CardDAV, and ActiveSync
Integrates with existing LDAP, Active Directory, and IMAP infrastructure
Proven at scale in production environments with thousands of mailboxes
Active commercial steward (Alinto) available for organizations that want paid support
Cons
Requires in-house IT expertise or a paid support contract to install, secure, and maintain
Web interface looks dated compared to modern SaaS email clients
No official cloud-hosted SaaS version directly from the core project, only third-party hosting
Documentation can be technical and geared toward system administrators rather than end users
