Does anyone I know host an instance of one of the following fedi servers (or can recommend an open-signup one)? I could use a test account on each one to test my API client for compatibility. Ideally with split-domain setup, if supported. 
- Sharkey, Iceshrimp.JS (or other Misskey flavors)
- GoToSocial
- Pleroma, Akkoma
- Friendica
- Pixelfed, Loops
- ... others I may have missed, except Mastodon, Iceshrimp.NET and Wafrn 😊

wafrn does not have split domain setup. https://app.wafrn.net only requires you to not use a vpn on registration
also: mastoapi on our side is far from done (search not done yet)
