I made this tool to help self-hosters, new admins, or smaller instances have more global and updated content on their instances.

This is the similar to Lemmy Community Seeder but is designed to be run periodically to capture new communities, and include EVERYTHING by default.

EDIT: As noted in the comments, this is an admin tool. Please do not run it as a user if you don't know what you are doing. If you want a better "All," ask your admin first! That said, lemmony in no way constitutes abuse! You can cause a DOS with curl, but that's not what curl was written for. This tool is to legitimately use an API to enhance our experience. Admins that desire to accommodate high volume on a public service will not know this tool is running against, or on their instances. If it causes performance issues, that is unfortunate. They are free to throttle, ban or block API access to their instance in a multitude of ways.

EDIT 2: Donate to your instance/admin if you like Lemmy!

I ran this and it causes a lot of load. Only issue is any user can run it so basically lemmy servers are pretty much open to be ddos attacked by a user subscribing to everything it seems. I have a pretty good server and it consumed 30% of the cpu continuously just adding all of lemmy.world. Unclear how much disk space I just commited myself to also. Small instances would be decimated by this. Wouldnt be hard for someone to load this docker up 10 times and pull from the biggest 10 lemmy servers all at once to max out a server and cause a lot of other issues.

Other than this, good job. Seems to work well. Maybe too well.

Added a lot of features if you want to try again.

I'd recommend anyone using this to really consider how much data this'll use on their system.

This is a neat idea. I'm guessing it's something the admin of the instance has to run?

If you are on a smaller instance you should probably ask the admin(s) if they are okay with something like this, it would put a lot of extra strain on the server and might overload small instances.

[-] hawkwind@lemmy.management 3 points 1 year ago

Technically no. Any user could. I wouldn't recommend it though, as it will subscribe you to every community.

I like this idea, I've been thinking about running my own private instance but decided against it as I like the main feed with many different communities that larger instances offer.

Hosting an instance myself, I’m not amused, because if forces my instance to literally sync all content there is on the lemmyverse, drastically increasing traffic, storage use etc.

Please don’t force resource consumption beyond any rational usage!

The weird rage people have about this. I'm not sure where it comes from. If there are 100 communities, only the top 1-5 will contribute 90% of the content. If you have even one user subscribed to the top 20 or 50 communities, you are already likely getting 90%+ of this traffic. After subscribing to literally every community in the lemmyverse, I promise your instance will not see any meaningful increase. I'm willing to be proven wrong, but not one of the ragers has offered a credible reason other than fears based on misunderstanding. No offense.
