Lemmy

It just needs more users and it's perfect.

Lemmy but with the resources to host video

A wiki with strong moderation tools, and gnupg signed/verified text built into it from the start.

An activitypub method to keep git repos in sync automatically.

A small blog type tool that's used as a replacement for facebook. It would have a hosted "gathering" component that is always online, then when you open your local app, it pulls down all your stuff.

Shared secrets like a distributed KeePass or Bitwarden.

Distributed home directory and/or development environments.

Something like the useful bits from KeyBase. I really wanted keybase to be something that could support this use case: Alice@foo gets a dev job at Bar. Her ID is added to the cool_project@bar group and automatically she has access to all the group's ~~big~~ bug tracking, file shares, wiki, git repos, group chats, etc. Her joining the group is recorded in a permanent record, which can be publicly or privately annotated by people specifically allowed by the group she joined. It'd become an automatic resume.

I'd really like to see some client-API consolidation. A common client API that could efficiently handle both "microblog" style and threaded discussions (lemmy etc) and leave the door open for other discussion formats too. This would allow for clients/frontends to flourish even more and backends could compete on features and efficiency. The backend specific features could be expressed through an extension mechanism of the common API.

Peertube but not written in JavaScript

It exists, it's Firefish, it has everything I need.
