On that note there's also https://tangled.org built on atproto which (kind of?) solves that. You have one identity (the same one for all atproto apps) which you use to interact with any tangled repository (including those on self-hosted servers).

With its support for self-hosted CI runners it could also be a good alternative for people looking to move now that GitHub has decided to charge for those.

I really like this atproto model so much.

Having one account/sovereign Personal Data Store that can hold many different kinds of data. Then having many different clients and services that are decoupled from the data, offering all kinds of experiences is just night and day better than everything else. For everyone.

You account works everywhere & that's awesome. You also have credible edit & can take your account to a different server without disruption, baked in: amazing win for sovereign computing & digital rights far better than (basically) anything.

People can make cool connected online services, without having to figure out how to host all the data! That's so powerful, so cool (and ActivityPub maybe can decouple someday, but we don't see it yet. The data store and the app go hand in hand, & you end up with an account for each service). It makes it wildly easy to build incredible connected services with fantastically little effort and costs.

That said, I did try to get some of my git repos on https://Tangled.org just today, and alas found that the actual git data needs a "knit" server to do that. And afaik there are are no knot servers I can just use. I'd never seen that complexity for a atproto app before! Usually with something like the book reading social app https://bookhive.buzz or the annotation service https://seams.so , just having your regular account is all the data & service you need. Tangled was a surprising contrast, but I hope to be online there sometime soon-ish!
