Projects using Ensembl

The Ensembl project is both a source of genome sequence related data (http://www.ensembl.org) and an open source software system that can be used to organise any such data.

User-contributed code

Whilst we have developed a comprehensive Perl API in-house, we welcome contributions in other programming languages from the community.


A Ruby API has been developed by Jan Aerts. A small example, showing what it can do (including coordinate transformation and reflecting on the types of associations for a given class) can be found on the wiki page.


An open source Java API (JEnsembl) has been developed by the Bioinformatics Group at The Roslin Institute. The code has been designed to be version-aware (a single installation works against current and previous releases) and is hosted, together with documentation, examples and contact information for the Roslin group, at SourceForge.

Note that we do not support these user-contributed packages - please contact the original developer if you have any questions or comments.

Ensembl-powered Websites

Some projects make use of the Ensembl software system, or are derived from it.
