Top.gg is the OG Discord directory. It has the most comprehensive list of Discord bots, and a very active community. The site goes down once in a while hence only 4/5 stars.
Has benefited my bot and community greatly! Submitting my bot was straightforward and with a custom HTML description it was easy to make my bot page look great
Best Website Ever, You Can Submit Your Programmed Bots For Free And Invite Most Upvoted/Popular Bots In The Most Easiest Way, You Can Also Submit Your Own Server(s) For Free Too
My experience overall was pretty good. They have built a strong community and the site itself is easy-to-use and errors get fixed in a good manner of time.
