The short version

  • Only Sakai has a free tier, so it costs nothing to try first.
  • Each has a real cost: Labster customization is limited and labs cannot be easily adapted to specific course learning outcomes; 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: Labster covers Virtual simulations, Sakai covers Course sites.
  • Prices and features above were last checked on 31 August 2026.

  • Remote educationnot Sakai

Sakai

  • A university whose data protection policy or national regulation requires student coursework to stay on institution-controlled infrastructure inside a specific jurisdiction.not Labster
  • 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 Labster
  • A university with an existing Java and Tomcat operations team, where the marginal cost of running one more Java application is genuinely low.not Labster
  • A consortium of institutions sharing one deployment and one set of local integrations rather than each paying separate per-student licences.not Labster

Where each one falls short

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

Labster

  • Customization is limited and labs cannot be easily adapted to specific course learning outcomes
  • Simulations can lag or freeze depending on operating system and connection speed
  • Cannot fully replace hands-on physical lab experience and data collection
  • Students report preference for tactile physical lab experience over virtual simulations

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

Labster: What STEM subjects does Labster cover?

Labster provides interactive 3D simulations across biology, chemistry, physics, and other STEM subjects, designed for university, college, and high school students.

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.

Labster: How many students has Labster served?

Labster has served over 6 million students and thousands of institutions globally with its virtual lab simulations.

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.

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.
