Can I host a Mastodon server in Replit?
You can look at their documentation for information (https://docs.joinmastodon.org/)
Also, you may want to boost and keep your Repl alive if the server is used on a large scale.
It might violate ToS but I don’t know, maybe look into that (hosting a server using Replit)? (I might be wrong)
It’s not breaking the TOS so long as the server does not perform any malicious actions or contain NSFW content.
