List of tools and services for altcoins.

[BTCat]

I would like to compile a list of (free) tools and services (not merchants) that support and implement crypto altcoins. Please help list any legit ones you know of. I cannot guarantee that they are safe to use, check yourself. Do not list coinspecific tools, any coin should be able to contact developer to support their coin. Mention type of service/tool.
