Fediverser Portal – Bring your subreddits to Lemmy
This is my attempt at helping those who are trying to ditch reddit but have not been satisfied with the content from Lemmy or haven't been able to find the corresponding communities. There are two sides to this project. The first one is that I have setup a Lemmy instance (alien.top) which is mirroring some of the reddit content from subreddits that I wanted to follow with the comments. The difference from most mirroring bots is that, instead of one single bot account mirroring all content, the system creates one account for each reddit user that is being mirrored. The other part of this idea…
In plain words
Fediverser Portal is a Lemmy instance that mirrors Reddit content to help users transition to the federated platform. It creates individual bot accounts for each Reddit user rather than consolidating posts under a single account, and allows Reddit users to authenticate via OAuth and take control of their mirrored account. The system automatically mirrors subscribed subreddits with their comments, addressing the challenge of finding equivalent communities on Lemmy.

This is my attempt at helping those who are trying to ditch reddit but have not been satisfied with the content from Lemmy or haven't been able to find the corresponding communities. There are two sides to this project. The first one is that I have setup a Lemmy instance (alien.top) which is mirroring some of the reddit content from subreddits that I wanted to follow with the comments. The difference from most mirroring bots is that, instead of one single bot account mirroring all content, the system creates one account for each reddit user that is being mirrored. The other part of this idea which I believe is more interesting: reddit users can take over their own mirrored bot account on this Lemmy instance. The instance itself does not use the regular registration process, but instead authenticates via Reddit OAuth. If you login through through the "Portal", we can then grab your subscribed subreddits and (when it can) find the corresponding Lemmy communities and subscribe you to those automatically. At the moment there are not that Lemmy communities that are being mirrored because I've been the sole user, but hopefully if more people sign-up, it will help to create the network effects and more instance admins will be interested in hosting these "fediversed" communities. All of the code is open source (https://github.com/mushroomlabs/fediverser) and I'm more than willing to help people getting their own instances if they don't want to use alien.top itself. Questions and any type of feedback is always welcome!

- HMHubski, my idea of a better aggregator2011 · ▲18
One year ago, I downloaded the news.arc code and decided that I would teach myself programming by building a better aggregator. At that time, I had some rudimentary HTML knowledge, and little FORTRAN under my belt. I knew that I wanted an aggregator that could support a wide range of submissions, and one that could scale without losing quality for the user. Hubski is what I have to show for my time and effort. The easiest way to describe Hubski is to say that it uses a commenting system akin to HN or Reddit, but uses a sharing scheme like Twitter. You have a personal feed comprised of the…
- AWA website tracking subreddit's active user so you know when to post2024 · redditdb.info · ▲8
I've tracked the top 3000 subscribed (and some subreddits that I visit frequently) subreddit's active user over time, so you know when to post to get the most feedback! I come from a nodejs background, and this is the first time coding with Go, so the structures might not be standard. But feel free to give me any feedbacks!
- HAHowsThisGoing – an AI based standup bot for Slack2024 · howsthisgoing.com · ▲9
Hey guys, I left my PM job in December to learn how to code. The plan, - Build something that "I" could build with my background (I haven't studied CS) - Something that already existed and I used so I didn't have to spend time finding PMF Over the past 4 months I've been building howsthisgoing.com (a standup bot for slack with AI summaries). My ex-employed signed up in May & I got another customer through a university batchmate sometime in June (the company he's working at). However, since then it's mostly been 0 new customers, I get roughly 6-10 views on my site daily. The bot and my…
