We have a standard! It’s this great decentralized VCS called git. For most of the stuff integrations do, they’re just showing code or commits — both of which are readily available in a copy of the repo.

Probably the one thing that’s missing is a standardized webhook system so that your git repo storage could tell integrations when stuff changes. Though even that isn’t strictly necessary if the integrations keep a copy of the repo up to date.

Git is absolutely miserable without things that GitHub, GitLab, and others provide, and there's still a huge ceiling to grow into in terms of layering on UX on top of Git.

In my opinion, Git is holding software development back. Git only cares about lines of text. This is not enough in today's world.
