Tripal is a toolkit for construction of online biological (genetics, genomics, breeding, etc), community database web portals, and is a member of the GMOD family of tools. Use Tripal out-of-the box to create a basic genomics site (with no programming) or customize using Tripal's Application Programming Interface (API).  Tripal is free and open-source (GNU General Public License version 2), allows for extensive customization and is backed by a helpful user community. A strength of Tripal is our community of developers. Customization and extension of Tripal can be created and shared with other sites as modules allowing you to create your own tools and visualizations or leverage those developed by groups around the world. To see what features Tripal provides, see the Tripal User's Guide and the Developer's Guide! If you have any questions, thoughts, or concerns, we would love to hear from you on our GitHub Issue Queue!
