Hi everyone. I'm trying to compile a comprehensive list of fanfiction resources—sites, forums, tools, and communities—that exist beyond the two biggest archives (AO3 and FanFiction.net). I've got a starter list from my own browsing, but I know I'm missing a lot, and I'm particularly looking for sites that recommend new stories based on user feedback or taste. I'd love your input.

Here's what I have so far:

General Forums/Archives:

• Questionable Questing, Sufficient Velocity, SpaceBattles (forums with heavy fic activity)
• Wattpad, Royal Road, ScribbleHub, Webnovel (often for original fic, but plenty of fanfic too)

Fandom-Specific/Specialty Hubs:

• Dark Lord Potter (primarily Harry Potter, especially darker takes, with other fandom sections)
• HPFanfiction Recommender

Tools, Databases, & Discovery:

• fichub.net (for downloading)
• ficdb.net (for tracking/discovery)
• Calibre + FanFicFare plugin
• Celestial Gambler
• Chaos Gacha by Bronz Deck

Communities (Reddit/Discord/Other):

• Subreddits: r/dark_fanfiction, r/NarutoFanfiction, r/WormFanfic (and many other fandom-specific ones).
• Discord servers (e.g., The Dark Wolf Shiro server, various fandom-specific servers). Examples: Gaming Omniverse, Celestial Emporium, Celestial Forge, Waifu Catalog
• Lemmy: I know of literature.cafe, but would love a fanfic-specific instance if it exists.
• NodeBB: Are there any NodeBB communities for fanfic or general literature?

Personal tracking lists:

• For example, my reading lists sorted by rating and last read

What am I missing? I'm especially interested in:

• Sites or tools that recommend fanfics based on your feedback or ratings (like a "if you liked this, try this" engine).
• Sites, forums, or communities specifically for dark fics, or for progression/system/gamer/litrpg fics.
• Other hidden gem forums, niche archives for specific fandoms, or lesser-known tracking/discovery tools.

Thanks in advance for helping build this out. I think a lot of us would find a master list useful for exploring new corners of the fanfic world!
