Do any fediverse alternative(s) for GitHub Gists exist?

There are lots of platforms connected together through the ActivityPub. Since I discovered the fediverse, I’ve used Mastodon, Lemmy, Pleroma, Writefreely, Mitra and Friendica, definitely leaving the centralized platforms for good.

However, as a developer, I’ve still been using centralized services, such as GitHub and, more specifically, GitHub Gists. Recently, I discovered a project called Opengist which allows for a self-hosted “GitHub Gists” alternative. While it allows for some integrations with centralized servers (e.g., integrated login using GitHub, GitLab, Atlassian Bitbucket, among others), it doesn’t seem to allow for ActivityPub integrations.

And this leads me to my question: are there any “fediverse GitHub Gists”, where developers could publish code snippets (e.g., P5.js snippets, GLSL shaders and fragments, mathematical experimentation, and so on), while allowing for federation? I imagine they’d be pushed to Mastodon and Friendica similarly as how Writefreely pushes posts to the fediverse, as a truncated text followed by a direct link to the Writefreely article.
