Hyrax is the next generation server from OPeNDAP. It utilizes a modular design that employs a light weight Java servlet (aka OLFS) to provide the public-accessible client interface, and a back-end daemon, the BES, to handle the heavy lifting. The BES uses the same handlers that are used with Server3 (also know as the CGI Server) but loads those at run time. See Hyrax configuration documentation and design documentation for detailed information about the server. Use the links of the left to download Hyrax.
- The servlet architecture is faster, more robust, and more secure than CGI invoked Perl scripts.
- A single installation can handle multiple data representations (hdf4, hdf5, netcdf, etc.)
- THREDDS catalog functionality.

This page provides a single place to get all of the packages that make up Hyrax and a simple way to find out which versions of those packages work together correctly. It's possible to get each of the packages from their own page, too. All of our software downloads are signed using GPG. Ask us for the public key if you want to verify the signatures. Other software you will need: Java, Tomcat, and optionally Apache.
