The short version

  • Each has a real cost: Krita not portable across Windows/macOS/Linux with consistent performance; Sakai the zero licence fee is misleading: running Sakai needs Java operations, database administration and upgrade testing capacity, and universities that costed only the hardware have ended up paying a hosting partner anyway.
  • They diverge on capability: Krita covers Digital painting, Sakai covers Course sites.
  • Prices and features above were last checked on 31 August 2026.

Sakai

  • A university whose data protection policy or national regulation requires student coursework to stay on institution-controlled infrastructure inside a specific jurisdiction.not Krita
  • An institution that has been repriced twice by a commercial LMS vendor after ownership changes and wants a platform with no owner to sell it.not Krita
  • A university with an existing Java and Tomcat operations team, where the marginal cost of running one more Java application is genuinely low.not Krita
  • A consortium of institutions sharing one deployment and one set of local integrations rather than each paying separate per-student licences.not Krita

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Krita

  • Not portable across Windows/macOS/Linux with consistent performance
  • Performance limits on large projects with many layers compared to professional software
  • Requires system administrator privileges for installation on managed systems
  • Limited professional support compared to commercial alternatives

Sakai

  • The zero licence fee is misleading: running Sakai needs Java operations, database administration and upgrade testing capacity, and universities that costed only the hardware have ended up paying a hosting partner anyway.
  • The third-party teaching tool ecosystem builds and tests for Canvas first, so Sakai adopters do their own LTI integration work and occasionally wait for a vendor to certify against a platform it does not prioritise.
  • Because governance is a foundation of member institutions rather than a company, a feature only gets built if some institution funds an engineer to build it, so roadmap commitments are weaker than a vendor contract provides.
  • The interface, while improved through the version 20 to 25 cycle, still reads as older than Canvas or Brightspace, and academic staff who have used a commercial LMS elsewhere notice it immediately.
  • Adoption is concentrated in specific regions and sectors, so the pool of people who have run Sakai in production is small, making it harder to hire an administrator than for Moodle or Canvas.

Answered from the vendors’ own pages

Krita: Is Krita free and open source?

Yes, Krita is completely free and open source software developed by the KDE community. It is distributed under the LGPL license with no licensing fees.

Source
Sakai: Is Sakai still actively developed?

Yes. Version 25.0 shipped in 2025, 25.1 followed in November 2025, and further maintenance releases in the 25 line are planned, with commits continuing through 2026.

Krita: What platforms does Krita support?

Krita is available for Windows, macOS, and Linux. It can be downloaded from krita.org or installed via package managers on Linux distributions.

Source
Sakai: Who owns Sakai?

No company does. Governance sits with the Apereo Foundation, a membership organisation of institutions, and the code is under the Educational Community Licence.

Krita: What animation capabilities does Krita have?

Krita supports frame-by-frame animation with onion skin view, timeline management, and export to video formats for creating animated sequences.

Source
Sakai: What does it actually cost to run?

The software is free. The cost is Java hosting and staff, or a commercial hosting agreement with an Apereo affiliate such as Longsight, typically quoted by student headcount.

Sakai: How does it compare to Moodle?

Moodle has a far larger plugin ecosystem and installed base; Sakai has a cleaner assessment and gradebook model and is more common in research-intensive universities. Moodle is easier to hire for.

Sakai: Can we migrate off it later?

Yes, but course content export fidelity through Common Cartridge is imperfect, so budget for manual rebuilding of assessments as you would leaving any LMS.
