Open-source PHP SIS · Self-hosted · Free community edition
OpenSIS is free.
Your time is the hidden cost.
OpenSIS is open-source software – free to download, installable on your own servers. “Free” in software almost always means “unpaid labor somewhere else.” OpenSIS needs servers, security patches, updates, hosting, and a technical person to keep it running. Development activity is limited in recent years.
Alma is priced so your team can focus on students – not on keeping the SIS online. Fully managed SaaS, AI analytics, modern UX, active development.
Where OpenSIS costs you in time
“Its weakness is limited development activity in recent years and no built-in modules for finance, LMS, or advanced features.”
– OpenEduCat open-source SIS comparison · February 2026
OpenSIS requires your team to run, secure, patch, and host the platform – the “free” price tag doesn’t include those costs.
– OpenEduCat · OpenSIS deployment requirements
“The software itself does not impose student count limitations – the constraint is server capacity.” Your infrastructure, your bottleneck.

Why schools choose Alma over OpenSIS.
Alma handles hosting, security patches, updates, and scaling – everything OpenSIS asks your team to manage themselves.
No servers, no patches, no maintenance
OpenSIS requires you to run, secure, and update your own servers. Alma is fully managed SaaS – we handle hosting, security, and updates so your team doesn’t.
Vendor support with a team to call
OpenSIS is backed by a community forum and paid services. Alma’s support team is a phone call or ticket away – with named humans who know your school.
AI-powered analytics, LMS, and modern UX
OpenSIS is focused and functional. Alma adds BeaconAI, an integrated LMS, modern UX, and active development – beyond what open-source maintenance can keep pace with.
Predictable pricing that includes the total cost
OpenSIS is free. Then come hosting fees, security, staff time, patching, and dev work when something breaks. Alma’s pricing includes all of it – so your budget is the budget.
“OpenSIS was free until we added up the server costs and the time our tech person spent keeping it running. Moving to Alma was cheaper once we counted the hours.”
– Technology Director, Private K-12
The bottom line

Alma is free of maintenance.
Designed for educators, not administrators
Alma’s interface is built around how teachers and counselors actually work, not around database architecture. Every click is intentional.
AI that surfaces answers, not more reports
BeaconAI turns raw SIS data into early warnings and actionable insights without requiring a data team to make sense of it.
A partner that picks up the phone
Alma customers consistently call out support as a standout differentiator. Real people, fast responses, no ticket black holes.
Implementation that respects the school year
No multi-year rollouts. No mid-year chaos. Alma’s onboarding is structured to get schools and districts live and confident before students arrive.
