A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.

Rules:

  1. Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.

  2. No spam posting.

  3. Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.

  4. Don't duplicate the full text of your blog or github here. Just post the link for folks to click.

  5. Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).

  6. No trolling.

Seedit is a selfhosted peer-to-peer Reddit Alternative using IPFS

doesn’t rely on any servers or instances .

We mainly use 3 technologies, which each have several protocols and specifications:

IPFS (for content-addressed, immutable content, similar to bittorrent) https://docs.ipfs.tech/ https://specs.ipfs.tech/

IPNS (for mutable content, public key addressed)

https://docs.ipfs.tech/concepts/ipns/

Libp2p Gossipsub (for publishing content and votes p2p)

https://docs.libp2p.io/concepts/pubsub/overview/

They also have a youtube channel where they cover how most of their tech works:

the problem with federated social media is that each federated instance is just a regular centralized sites. They can censor each other, they can get taken down at any moment, and they are hard to run and manage. Whereas on p2p tech like bittorrent or bitcoin or plebbit, the p2p nodes don't require domains, they just work straight out of the box. On plebbit, you open the app, and you're instantly receiving p2p connections right away, just like a bittorrent client, no domain or server required. Users connect to your node directly, p2p, and nobody can stop you. P2P also scales infinitely, which is the reverse of centralized websites like federated instances: the more users there are, the faster it gets. And it's impossible to censor at scale.

Seedit is not Nostr

nostr isnt p2p, the relays can censor you, the relays can run out of money and shut down, the relays can get DDOSed, they earn no money to serve your content.

the people running the relays are probably legally obligated to censor you by their jurisdiction. for example in the UK you go to jail for mean tweets. the person running the relay with mean content would probably go to jail if they set foot in the UK.

CP

  • the protocol is text only, to embed media, you need to host it on the regular ( Centralized ) internet, and then you link to it like https://example.com/image.jpg, and the host will stop hosting that image and report your IP.

  • the community creator can assign mods, mods can remove posts from that community. if a community is badly moderated, the user will never see it, it wont be recommended to him. the user can visit bad communities directly just like you can visit a bad website directly, but it's not recommended to you so it's safe to use.

it’s the same as bittorrent , this p2p tech can’r prevent people from sharing stuff, but on seedit you can’t share media, it’s text-only so the liability falls to the centralized provider of the embedded media from the link the user shares as text. Also being p2p, seedit is not private, so it can’t really be used for illegal activity

About ActivityPub

the problem with federated social media is that each federated instance is just a regular centralized sites. They can censor each other, they can get taken down at any moment, and they are hard to run and manage. Whereas on p2p tech like bittorrent, p2p nodes don't require domains, they just work straight out of the box.

Also the code is fully open source

Uhh... No, your link is to Github. If Microsoft decide they don't like something you're doing, they can wipe your app off the surface of the planet. At least mirror it to Codeberg or something.

Same thing for Google and Apple by the way, if you want to make a mobile app. They don't like you, you're gone from their platform.

They can make you life harder, tracking you, sending you to jail etc but they can’t prevent the initial p2p connection.

Honestly, if I were doing anything that required a uncensorable network connection, "avoiding going to jail" feels like it'd be one of my top priorities...

Also, no, base64 encoding isn’t allowed in the protocol, you literally can’t publish it to the p2p network because there are character limits.

What are you going to do? Ask people politely to not do it?

Nope, how would that make any sense? A community is such if it’s moderated. If it’s unmoderated, it’s not even a community, it would be fully unusable because of spam.

Every time Plebbit has been shilled here, the advertising has always criticized "power-tripping" Reddit and Lemmy[sic] mods and tries to place itself as a "free speech" platform.

Our clients use https://github.com/plebbit/temporary-default-subplebbits

So your decentralised peer to peer platform has a list of curated nodes that must have nearly 100% uptime.

you can query the ethereum and solana blockchains for .eth and .sol domains respectively with text records/subdomains of value “subplebbit-address” (see: https://dune.com/plebbit/plebbit-protocol) and we’ll support more decentralized domain systems later.

Just copy ATProto and use did identifiers with DNS. No need to use blockchain for name lookups.


Okay, this project has consumed too much of my time so... I'm probably just going to leave it here. However I do have some last thoughts.

I agree that ActivityPub does have centralization problems. It's mostly decentralized, but has problems with having many small kingdoms that tend to not always get along. I think that's something that ATProto gets right; your name and "instance" are decoupled so it's trivial to hop from one to another. And honestly, I think a Lemmy-like built on top of ATProto could work really well, and may even be better than AP based ones.

But... This project seems to be reinventing the wheel for no good reason. It ignores existing technologies in favour of venture capitalist scams. It has a very muddled set of priorities. The project management is sending out massive red flags. I don't have trust that this project will solve the problems with Lemmy and Reddit.
