Koha vs Alma: Open Source vs Cloud ILS Comparison
Comparing Koha open-source ILS with Ex Libris Alma — features, cost, data ownership, and which is right for your library.
Alma from Ex Libris (a ProQuest/Clarivate company) is a cloud-native library services platform widely used in academic libraries. Koha on AWS Cloud, deployed and managed via KohaSupport, is a compelling open-source alternative that brings enterprise-grade cloud hosting to the world’s most popular open-source ILS. This comparison reflects what KohaSupport’s Koha actually delivers — not vanilla self-hosted Koha.
Quick Comparison
| Factor | Koha on AWS Cloud | Alma |
|---|---|---|
| Cost model | Open-source deployment; cost depends on hosting, support, and implementation choices | Annual subscription (cloud SaaS) |
| Vendor | Open-source community | Ex Libris (Clarivate) |
| Deployment | AWS Cloud — your account, your chosen region, 5-minute setup | Cloud only (Ex Libris data centers) |
| Data ownership | Full — choose your AWS region, meet GDPR/local data laws | Vendor-hosted in Ex Libris data centers; export possible but complex |
| Electronic resource mgmt | Built-in ERM module (agreements, licenses, eHoldings, COUNTER/SUSHI) | Built-in (Alma’s core strength for large portfolios) |
| Discovery layer | Koha OPAC or third-party (VuFind, etc.) | Primo VE (additional cost) |
| API / integrations | Open REST API, no fees | API access available, some restrictions |
| Customization | Unlimited — open source | Limited to vendor-provided configuration |
| Target market | All library types | Academic and research libraries |
| Release cadence | Quarterly | Vendor-controlled, continuous |
| Contract flexibility | No lock-in | Multi-year contracts typical |
Where Alma Has an Edge
Electronic resource management at scale: Koha now ships a full ERM module — agreements, licenses, eHoldings (with direct EBSCO HoldingsIQ integration and local KBART holdings), COUNTER 5/SUSHI automated usage harvesting, and usage reports. For most academic libraries this covers the full e-resource lifecycle. Alma’s ERM still has an edge for libraries managing very large, complex e-resource portfolios (many thousands of packages, multi-vendor consortial activation) where Alma’s tighter integration with its own knowledge base and Primo discovery layer provides a more unified workflow.
Unified platform: Alma is designed as a single platform for print, electronic, and digital resources. Koha handles print circulation and cataloging excellently; complex e-resource and digital asset management typically requires additional tools.
Consortial reporting: Alma’s analytics and reporting across consortium members is sophisticated. Koha’s reporting is SQL-based and powerful but requires more configuration.
Where Koha Has an Edge
Cost: Alma subscriptions at academic institutions typically run well into five figures annually, plus Primo VE for discovery. Koha’s total cost of ownership is substantially lower — see Total Cost of Ownership for a Library ILS.
Data ownership: Koha on AWS Cloud gives you full control over your data and where it lives. You can choose the AWS region (for example, US East, EU Central) to store your data, keeping you compliant with data regulations like EU GDPR. Alma stores your data in Ex Libris data centers — data portability is possible but not seamless.
No vendor lock-in: Switching from Alma involves negotiating data exports and contract terms. With KohaSupport, your Koha instance runs in your own AWS account — terminate the subscription and keep running Koha independently. Your MARC data and patron CSV are always exportable with no permission required.
Customization: Koha can be modified at any level. Alma customization is limited to what Ex Libris exposes in configuration.
Cost scaling: Alma pricing often scales with FTE, number of items, or institution size. Koha costs don’t scale with your collection size.
ERM in core Koha functionality: Koha’s ERM module — agreements, licenses, eHoldings, EBSCO knowledge base integration, and COUNTER/SUSHI usage statistics — is part of core Koha. When comparing with Alma, evaluate the broader hosting, support, migration, and service scope rather than assuming module pricing maps directly.
The Academic Library Decision
Choose Alma when:
- Your library manages a large e-resource portfolio (thousands of e-journal packages, database licenses)
- Your institution is part of a consortium already on Alma
- Your library has minimal IT resources and wants a single vendor for software, infrastructure, and support (note: KohaSupport on AWS also handles all infrastructure management, removing this as a Koha barrier for most libraries)
- Budget is not the primary constraint
Choose Koha when:
- Budget is a significant constraint
- Your collection is print-heavy, or your e-resource portfolio is manageable (Koha’s built-in ERM handles agreements, licenses, EBSCO eHoldings, and COUNTER/SUSHI usage stats)
- You want full data ownership and no vendor lock-in
- You want to customize workflows and integrations without vendor involvement
- You are a small-to-medium academic library, community college, or school
Cost Comparison Framework
Rather than publishing specific figures (Alma pricing varies significantly by institution size and negotiation), consider these categories:
- Alma annual subscription: Typically covers software, hosting, and support as a bundle
- Primo VE (discovery): Usually an additional line item
- Koha: Budget around hosting, support, migration, and implementation scope — see ILS TCO guide
Most libraries switching from Alma to Koha report significant multi-year savings. The trade-off is taking on more responsibility for system management (or paying a hosting provider to do so).
Migrating from Alma to Koha
- MARC records export from Alma as MARC21 — clean import into Koha
- Alma stores some data outside MARC (e-resource records, portfolio data) — these require special handling
- Patron data exports as CSV
- Circulation history is exportable but mapping requires planning
- Typical timeline: 4–6 months

Koha via KohaSupport — Managed Cloud Without Vendor Lock-In
Libraries migrating from Alma often worry about losing the managed infrastructure and support they’re used to. KohaSupport bridges that gap — giving you Alma-style cloud convenience with full data ownership:
| Feature | Self-hosted Koha | Koha on AWS Cloud (KohaSupport) |
|---|---|---|
| Setup | Manual Linux install (hours–days) | AWS Marketplace — up in 5 minutes |
| SSL/HTTPS | Manual Apache config | Auto-configured on first boot |
| OPAC branding | CSS editing in system preferences | Koha Theme Builder plugin — point-and-click branded catalog |
| Backups | Manual cron setup | Automated daily S3 backups to your own AWS bucket |
| Infrastructure | Self-managed server | CloudFormation-automated stack on your AWS account |
| High availability | Manual setup | Multi-AZ, auto-scaling, 1–35 day PITR (Enterprise tier) |
| Support | Community forums | KohaSupport team — dedicated support SLA |
| Data ownership | Your server | Your AWS account and chosen AWS region — supports data residency and governance requirements; final compliance depends on your configuration and policies |
The result: open-source flexibility and data portability with a managed, cloud-native deployment model in your own AWS account. Compare overall cost using a full TCO framework rather than assuming a single savings ratio.
Pricing combines the KohaSupport subscription with your own AWS infrastructure costs — giving you full, granular control to right-size and optimize your infrastructure spend as your library grows. See plans and pricing →
