Lemmy VS Reddit

Lemmy is an open source, federated forum system with lots of sites and users:

It does not have as many users as Reddit, but a Reddit paywall might drive more users to Lemmy sites or other alternatives.

There already is a Reddit-like application that uses ActivityPub. It's called Lemmy (https://join-lemmy.org/).

Lemmy: A decentralized, open source platform that mirrors many of Reddit's features

Lemmy is one such alternative. I follow a few instances.

Surprised no one mentioned ForgeFed [0]:

> ForgeFed is a federation protocol for software forges and code collaboration tools for the software development lifecycle and ecosystem. This includes repository hosting websites, issue trackers, code review applications, and more. ForgeFed provides a common substrate for people to create interoperable code collaboration websites and applications.

It's based on ActivityPub [1], the same protocol that powers Mastodon [2], Lemmy [3], and Pixelfed [4].

Lemmy is like Reddit and here because it has threaded comment discussions.

It's also federated, so you can pick a server you like and have discussions with users from various servers together.

Some Reddit apps switched to supporting Lemmy instead when they were kicked off the API.

Reddit has over half a billion accounts as of 2024. To support that, they use PostgreSQL as a ThingDB (sort of key-value store) and as a regular SQL database. See more in their write-up.

Slashdot, reddit, and HN are similar in that the source code was available. For HN, as part of arc under the Artistic license. All 3 abandoned public source code releases.

While it would likely have zero overlap with the code in use today if you look at the old code Reddit used to publish for voting the model at that point used to have flags/checks for :

I've been trying to host my own instance of Reddit from archived source code on GitHub. Even though I am aware that's probably not a good idea since many dependencies are broken and there's practically no documentation on anything (and it's really old legacy code), but I still decided to give it a shot.

Shh, don't tell spez, the code is already available on the github https://github.com/reddit-archive/reddit/

Automod to act based on keywords/domains/etc., ideally using the same language/flags/regex/etc. of the original automod (old code) so that it's possible to use existing code. (For detecting off-topic posts, enforcing a title format, reminding the users to add missing details to post, filtering profanity, shadowbanning spammers, etc.)

Reddit pre enshittification is actually open source so spinning up your own Reddit instance should be trivially easy. I’m very surprised no one did this after the API protests started

There are already 1:1 reddit clones based on older versions of their software that was open source: https://github.com/reddit-archive/reddit
