I co-maintain the ActivityPub watchlist, which is input to Fediverse Party as applications mature, and I have added Fedeproxy to the list. The list is very handy once you start developing, to find other projects in your language of choice to study their codebase.
In addition I have created the ActivityPub developer watchlist with developer tools, frameworks and things like that, where you’ll find Go-Fed and Forgefed.
