I’m posting on behalf of another user on Reddit,u/TasmanianHorse, who’s exploring the possibility of integrating their platform (Echo, Pinterest alternative) into the Fediverse using ActivityPub.

I recommended the Fediverse to them earlier on, and they’re interested in making their platform interoperable with existing services (like Mastodon, Lemmy, Peertube, Pixelfed, Loops, etc.), but are still in the early stages and looking for guidance.

Some of the questions that they had:

• What are the main challenges when implementing ActivityPub from scratch?
• Are there recommended libraries, frameworks, or starter projects to build on?
• How difficult is it to ensure compatibility with multiple Fediverse platforms?
• Any common pitfalls or things to avoid early on?
• Are there best practices for moderation, federation control, or scalability?

If anyone here has experience developing for the Fediverse or has worked with ActivityPub, your insights would be really appreciated.

Thanks in advance!

EDIT: They also have an e-mail address, that they have said that users can reach them at, if they have feedback /feature suggestions regarding Echo.
