Is there a reason why all the services, that use the ActivityPub protocol don’t have a unified API?
None of the mastodon apps allow me to log in with a lemmy/kbin account.
Also none of the lemmy apps allow me to log in with a kbin account.
Even though kbin has both mastodon (microblogging) and lemmy (threads, communities) functionality.
Also, Pixelfed recently introduced “login with Mastodon”, but all it really does is just create a new user on it’s instance and copy over the mastodon followers and profile info.
Why can’t we just have one account to rule them all?
Because they are still different apps with different needs, architectures and formats. They just synchronize most of their content between each other.
Most Fediverse apps implement the Mastodon API. Lemmy and Kbin are kind of weird in that they don’t, but their upvote based system doesn’t really stroke with most existing Fediverse applications anyway.
ActivityPub does have a client-to-server API but very few servers actually bother to implement it and it’s very barebones. I believe Akkoma supports it and a few experimental servers that don’t have a user serviceable frontend, but that’s about all I know.
In theory this stuff isn’t really necessary. There’s no reason why you can’t combine the ActivityPub queues for different servers, allowing you to use the same account everywhere. This would need to submit outgoing content back to other services to keep them in sync and possibly proxy and keep track of posts hosted behind the proxy to make sure duplicate IDs don’t become a problem, but it can be done.
A theoretical fix for this would be to proxy all ActivityPub requests for different services hosted on a website through a program that will do the actual federation work. I practice, following a single Lemmy server will cause your entire Mastodon timeline to be comments to posts you can barely even see. The flat list approach Mastodon and most Fediverse applications take doesn’t work well with hierarchical posts Lemmy and Kbin offer. Try following a few Lemmy/Kbin communities and you’ll see what I mean.
In practice, everyone is doing their own thing. The single sign on options work like logging in with Google/Facebook/Twitter does, creating new accounts without passwords you can use from a single place.
As for the technical reason why you can’t use the same username@domain for multiple services: ActivityPub, the protocol federating most Fediverse servers, works by using WebFinger to look up an account based on an account name. This will let an external server obtain the location of your account details.
Your account details contain a number of collections (posts, likes, favourites) that can be fetched remotely. How these are made available is up to the individual server. Mastodon, Lemmy, Kbin, and every other tool all contain code to generate the JSON documents that comply with this format.
However, these tools are all different internally. Different programming languages, different database layouts, different database engines, different features and protocol extensions, different URL formats, different post IDs, different everything. You can’t just point Pixelfed at a Mastodon server and tell it to go fetch some content, because Pixelfed’s client-server API is different from Mastodon’s.
With extensive work, these tools can all be made to work together under a single username. Every tool needs to be made aware of every other tool, and a lot of the actual federation code needs to be externalised to an all-encompassing server. This can be done without breaking any spec and without becoming incompatible with the rest of the Fediverse, but it’ll require a LOT of work.
If you have the skills to make these modifications, or the money to pay people with those skills, you can make it happen. It’s just not something different Fediverse servers are going to put a lot of effort into any time soon.

You basically summarized my original plan for communick. The basic idea is:
- Take the existing services, provide commercial hosting
- Use the revenue to fund development of protocol-level integrations, contribute back to open source
- Build tools to make it easy for companies to migrate away from Facebook/Twitter/Instagram/WhatsApp and own back their internet presence again
- ???
- Profit / Destroy Big Tech.
Unfortunately, the amount of people willing to pay for commercial providers of social media is embarrassingly small, so I am stuck at step 1 and the best I could do is to build a SSO system for Matrix/Mastodon/XMPP, to let people use the same credentials on all “communick.com” servers.
I’ve been thinking of writing up a script to deploy a single Mastodon+Matrix+Kbin+whatever service through Keycloak and something like Ansible, but OAuth2 implementations seem to mostly focus on big social media companies rather than arbitrary SSO. Matrix has native SSO support, but even XMPP doesn’t seem all that well set up for federation (maybe an XMPP bridge would help?).
I don’t have time to put into this idea and I don’t think it makes much sense as a business model, sadly. There isn’t much interest in hosting your own socials. That said, with Threads and Tumblr coming in, I can see a potential for mainstream users. I don’t think they’ll be interested, but imagine a tech brand like LTT coming in with a federated forum for customer/community interaction, Matrix for chat, Mastodon for social media outreach, all behind one secure login system, delivering content and community to the Fediverse, Threads, and Tumblr. Perhaps integrate this with a Twitter API client for an appropriate price to help web care resolve the signatures at the end of messages (“^FL”) by using the domain name as a verification system and the agent’s username rather than adding signatures everywhere.
It’s going to be a tough sell, but with a bit of luck and a few years of growth I think it may happen. You’d also need to loop in platforms like Bluesky over course, which will be more difficult but it’s still technically feasible.
I was also considering taking a lightweight Matrix implementation (Hydrogen?) and stuffing it into a Lemmy frontend to provide more secure DMs. That’s more work to maintain long term, though.

Exactly! This also applies for old media as well. Why is it that the NYT, WaPo, WSJ, Deutsche Welle, Globo, Telemundo, Forbes et caterva haven’t still set up their own AP servers? I guess they seem as more interesting to go to Twitter and bitch about Elon Musk instead of just emptying the platform? Why can’t they become providers of a service and say “all subscribers get a free account”?
Currently, the entire Fediverse is equal to what, two percent of Twitter’s userbase? Maybe 10% if you take out all the Twitter bots? Twitter is used for outreach, but with nobody to follow you, there’s no incentive for companies to join the Fediverse.
This can change once some social media with actually relevant user bases start joining the network (Threads, Tumblr) but until then I wouldn’t expect any companies to bother.
I don’t think it’d be a good idea to put journalists on an instance with their publication, though. Sure, they should use the verification feature Mastodon provides, but you don’t want a journalist’s socials to be in the hands of their boss.
Complaining about 𝕏 makes sense for as long as there are more active people on there than there are on any of their competitors. People don’t want Twitter do die and wither away, they want it to go back to the way things were before mister “make se𝕏ual assault cases to away by giving her a horse” took over.

I’d honestly say it’s even less and I’d even wager that the amount of bots here are even higher (percent-wise) than Twitter. I’m working on a search engine for the fediverse now, and I was surprised with the amount of bot accounts and mirror servers that I am finding.

I feel quite the opposite. If a journalist is really independent, then they can go on to host their own content. But as long as they are writing under the editorial guidelines of some larger institution, I want this association to be well defined and transparent.
People don’t want Twitter do die and wither away.
I am fundamentally opposed to any ad-funded business. I honestly believe that moment a lot of the issues in our society can be traced back to the moment that we made it possible for people to make a living by just collecting eyeballs instead of focusing on quality work at a small scale. So, yeah, I very much want Twitter/Facebook/Google to die and wither away.
