Koha Is The Best Value For Your Money
Unlike commercial software, Koha is an affordable, cost-effective solution for any size library.
Perfect for all budgets, great and small

Affordable: Koha is an open-source software and it therefore costs a fraction of what you would otherwise pay to buy, install, and run commercial library management systems such as Sierra, Millennium, Horizon, and others. You can save even more money and time when you sign up for Koha cloud hosting by established support providers.
Library Standards Compliant. Koha is built using library standards and protocols such as MARC 21, UNIMARC, z39.50, SRU/SW, SIP2, SIP/NCIP, ensuring interoperability between Koha and other systems and technologies, while supporting existing workflows and tools.
Web-based Interfaces. Koha’s OPAC, circirculation, management and self-checkout interfaces are all based on standards-compliant World Wide Web technologies–XHTML, CSS and Javascript–making Koha a truly platform-independent solution.
Free Software / Open Source. Koha is distributed under the Free Software General Public License (GPL) version 3 or later.
No Vendor Lock-in. It is an important part of the free software promise that there is no vendor lock-in: libraries are free to install and use Koha themselves if the have the in-house expertise or to purchase support or development services from the best available sources.
