Annovar is no longer available. Why? The original tool author doesn’t want it to be available open source. They may have left the wrapper in the Tool Shed, and that version worked with just one genome (hg19) with earlier Galaxy versions but not likely with current versions. I don’t know the status beyond that and we’ve removed it from the public servers.
If it still interests you, you should contact the tool author directly to see if they will offer a site license for private use and maybe some custom advice for getting more genomes supported, or even hg19 again, plus help with any wrapper updates that may be needed.
As for paying for support, the core team releases everything – all software and all computational infrastructure at public servers – for free with zero monetization. That means others can offer pay-for-service flavors, and they do!
Review here for all of the choices we know about.
And, if the configuration for a stand-alone server seems to include more than you need, we do offer a free Docker version to consider. Same page as the two before but I’ll quote here directly.
And finally, there are many Matrix chats you can visit for one-off administrative questions. These reach the developers directly, both core team and community contributors. We are organized into Working Groups and the resources for all can be found here, including the chats. → Galaxy Working Groups - Galaxy Community Hub
