Still works fine for me. Redlib is operational, but it’s a work around at best and will likely sunset at some point. To my knowledge their method is to employ guests accounts to scrape reddit content.
It still works for private instances. The moment a public instance makes enough requests to reddit, they block it.
I'm running libreddit on my home server and access it through wireguard. Never been rate-limited. It's the only thing I still use Libredirect, since most platforms ban third-larry frontends.
Libredirect is great, but it's usefulness is waning. The frontends for Twitter and Instagram no longer work which hurt the usefulness. The frontend for TikTok is great when it works, which is only about half the time.
