Here is my attempt to archive r/homelab before it went dark. Google says there about 92,400 results for site:reddit.com/r/homelab, I have 2098, that’s only about 2% of it. Maybe there is something of use to you in that 2%.
Please don’t webscrape, if you want all the data you can get the raw BDFR archive at https://archive.douwes.co.uk/reddit/homelab.tar or the live web version at https://archive.douwes.co.uk/reddit/homelab-web.tar
Also as many people come to r/homelab via Google, putting cache: before the https:// in chrome will yield the google cached page, which doesn’t go to reddits servers. Also to be clear the mods of r/homelab have no intention of nuking the sub and losing any existing data but appreciate the efforts being made by users and r/datahoarder.
