Koha is a web-based ILS, with a SQL database (MariaDB or MySQL preferred) back end with cataloguing data stored in MARC and accessible via Z39.50 or SRU. The user interface is very configurable and adaptable and has been translated into many languages. Koha has most of the features that would be expected in an ILS, including:
- Various Web 2.0 facilities like tagging, comment, Social sharing and RSS feeds
- Union catalog facility
- Customizable search
- Online circulation
- Bar code printing
From 2000, companies started providing commercial support for Koha, building to more than 50 today.
In 2001, Paul Poulain (of Marseille, France) began adding many new features to Koha, most significantly support for multiple languages. By 2010, Koha has been translated from its original English into French, Chinese, Arabic and several other languages. Support for the cataloguing and search standards MARC and Z39.50 was added in 2002 and later sponsored by the Athens County Public Libraries. In France Paul Poulain co-founded BibLibre in 2007.
In 2005, an Ohio-based company, Metavore, Inc., trading as LibLime, was established to support Koha and added many new features, including support for Zebra sponsored by the Crawford County Federated Library System. Zebra support increased the speed of searches as well as improving scalability to support tens of millions of bibliographic records.
In 2007 a group of libraries in Vermont began testing the use of Koha for Vermont libraries. At first a separate implementation was created for each library. Then the Vermont Organization of Koha Automated Libraries (VOKAL) was organized to create one database to be used by libraries. This database was rolled out in 2011. Fifty-seven libraries have chosen to adopt Koha and moved to the shared production environment hosted and supported by ByWater Solutions. Another consortium of libraries in Vermont, the Catamount Library Network has also adopted Koha (also hosted by ByWater Solutions). Previously automated Vermont libraries used software from Follett, or other commercial software vendors.
In 2014 the Ministry of Culture (Turkey) started to use Koha -- Devinim  version in 1,136 public libraries with more than 17,000,000 items and app. 2,000,000 active users. This is the biggest Koha installation for the moment. 
Increasingly, specialized libraries such as music libraries, adopt Koha, as its open-source nature offers easier pathways to customization for their particular use cases. 
Dispute with LibLime / PTFS
In 2009 a dispute arose between LibLime and other members of the Koha community. The dispute centred on LibLime's apparent reluctance to be inclusive with the content of the sites and the non-contribution of software patches back to the community. A number of participants declared that they believed that LibLime had forked the software and the community. A separate web presence, source code repository and community was established. The fork continued after March 2010, when LibLime was purchased by PTFS.
In November, 2011, LibLime announced they had been granted a provisional trademark on the use of the name koha in New Zealand by Intellectual Property Office of New Zealand. The Koha community and Catalyst successfully appealed against the provisional trademark grant, with a decision handed down in December 2013 and with Liblime to pay costs.
Koha is currently a very active project. According to ohloh (now OpenHub), it has a [v]ery large, active development team and a [m]ature, well-established codebase, with hundreds of contributors and over 20 monthly contributors each month from 2011 to 2019.
Koha releases follow a regular, calendar based, pattern with monthly maintenance releases and bi-annual feature releases.
