Gibbon versus openSIS | Student Information & School Management Software
Compare	Gibbon	openSIS \| Student Information & School Management Software
Verdict	Depends	Depends
Best for	Schools with in-house IT	K-12 schools wanting a full SIS
Who it's not for	Schools without a sysadmin . the CVE history demands fast patching	Tutoring centers and after-school programs . heavy overkill
Privacy	Rough record: multiple RCE, SQL injection, and file-inclusion CVEs between 2023 and 2026; patching discipline is mandatory.^⁹	No known public vulnerabilities found in the sources reviewed.
Support quality	Guess: community forum support, no vendor SLA	No direct support reviews found
Public sentiment	No substantive user reviews of the school platform surfaced; most 'Gibbon' search results concern unrelated products like slacklines and speakers.^⁵	Independent user reviews are scarce; the only quoted testimonial appears on the vendor's own site.¹⁶
Biggest gotcha	Self-hosted: you provision hosting, run upgrades, and must patch fast when RCEs land^¹	No security page found on vendor site; request security documentation directly
