At least, other ones running on the otw-archive software!

SquidgeWorld Archive

Open to all fandoms, SqWA is run under the nonprofit squidge.org! In addition to the archive there, Squidge also offers image hosting, podfic hosting and a bunch of other excellent services. Beyond that, it utilizes more extensive archive warnings than AO3 and also accommodates two additional relationship categories! SqWA has a no-AI policy that is both up front legally and implemented behind the scenes through various coding measures.

The TOS is here. The information about the additional warnings can be found here.

Ad Astra :: Star Trek Fanfiction Archive

A single-fandom Star Trek fanfiction archive, this one's home for any and all Trek fandom! Using the same warnings as AO3, but a much stricter (and therefore searchable) tagging scheme, Ad Astra's also connected to one of the friendliest and most supportive Trek communities on the internet! We run weekly challenges, monthly review/comment hunts and like the other archives, we take a very hardline stance against AI both in actual terms and in firewalling the site. AI 'bots can't even reach the server before getting sucked into a black hole of 4XX errors and bannination jail!

There's an additional QPR (Queer-platonic relationships) tag accepted in the form of Character A ~ Character B, as well. Two invitations go out once a day, unless you want to contact me directly, then I can send one immediately.

Find the site FAQs here, please pay special attention to the posting rules!!

superlove

Run off of a macbook by a very talented young person, superlove is for all fandoms and original fiction and pretty much whatever else melo wants to open the doors for! In addition to the same archive warnings and relationships available to people using AO3, superlove also has a few more warnings that users can use and both QPR and vs. tags for queer-platonic and adversarial relationships. Given this is largely a private project, please make sure you review the rules carefully.

Comic Fanfiction Authors Archive

The CFAArchive is an archive built specifically for comic book and comic animation adjacent fandoms, rather than live-action properties! It uses the same archive warnings as AO3 and Ad Astra, but has the two additional tags QPR and vs. for queer-platonic and adversarial relationships! Much like Ad Astra, the tagging scheme on the CFAA is very strict to maximize searchability and minimize tag-spamming. There's also an attached Discord, where we run a bi-weekly writing challenge, the occasional comment/review hunt and a monthly focus feature where everyone reads a book, discusses it and creates based on it! If you love comic books and comic animation properties, this is the place for you!

Much like Ad Astra, the filtering out of AI 'bots is extremely strict; they get 4XX'd into oblivion and so far, none have gotten through since the new firewall rules were implemented, so you actually can leave works unlocked if you like with minimal (though never nonexistent) concern about them being scraped.

Two invitations go out once a day, unless you want to contact me directly, then I can send one immediately.

While I strongly appreciate that message, being a firm believer in independent archives and a decentralized fandom umbrella, I can guarantee the people typing that as a 'gotcha' to the antis -- who are reprehensible at the best of times -- are not one of the people who got otw-archive running on a server with actual humans using it because there are only two of us. And again, I'm one of them. @squidgiepdx is the other.

There are only two of us because it's a viciously badly optimized disaster of software involving so many running processes in so many different languages that it took me fifty hours of work just to get it marginally functional and many more dedicated hours since then maintaining it. It constantly runs at 95% RAM usage on our server. I have a beautiful single-fandom archive for the effort, but by god, I am so, so tired of people who know jack shit of what they're talking about pretending like it's as easy as unzipping a package and making it run.

SquidgeWorld took so fucking much work. Walter did that. Ad Astra took so fucking much work. I did that. And we are both willing to help other people do that! We are both incredibly happy to offer our time and expertise to anyone else who wants to help us become more than TWO PEOPLE OUT OF SEVERAL BILLION to make that software run for archives that don't belong to OTW.

Literally the only thing otw-archive collects as information about its users. That's it.

ETA, a more detailed writeup:

This is literally all anyone can see from the back-end of otw-archive, which runs AO3, CFAA, Ad Astra, superlove and SquidgeWorld Archive. The software collects no real user data. The IP address shown here is the localhost, which means we can't even see your IP address from the software itself. You have to legitimately go into the back-end server logs and play 'find one of the millions of unique users and somehow -- almost impossibly -- match their IP to a username'. But even if they somehow managed to miracle that into existence, you could defeat it in two seconds flat with a VPN. Not that it's likely they could.

This should hopefully demystify exactly what all AO3 really collects on its users. It's not much. It even makes it pretty hard to stop spammers/scammers/other bad actors because they collect so little. Even on my comparatively tiny archives, I had someone circumvent a ban because there was no way to prove it was them until they slipped up and screwed up.

Even then, if somehow they knew your username and IP address (almost impossible) there's no way AO3 knows your wallet names. Not even if you're a member and donate; they intentionally keep their archive userbase and donation databases separate!

Your identity is safer on an otw-archive installation than it is on almost any other website out there. Not only isn't OTW selling your information, they don't actually have any to sell.

So, it's not open yet, I still have a bunch fiddly little stuff, including the hardcoding, the mailers, etc., never mind getting the mail server up and running correctly so that gmail stops intercepting. BUT-- the majority of it's at least there and stable.

Some neat things we have:

A canonical QPR relationship category! A canonical vs. relationship category! Tag discipline! So much tag discipline!

However-- I need some help. Namely, I need a Marvel Comics (not MCU) aficionado. I was big into the X-books back in the day, but it's been like two decades since then, so when it comes to building the categories, tags, etc, I would like someone or a couple someones with more recent experience than that.

I also wouldn't mind someone from the smaller companies, while we're at it.

Boldly Writing is going to hopefully be the nonprofit for indie archives; the ultimate plan is to give us an umbrella org that lets donations to our archives, etc. be tax-deductible, allows us to access a lot of services for free or reduced cost through the org and otherwise lets us move forward with championing the causes of more independent and decentralized fan communities while still providing the social networking and cohesion of a single community over all.

My ultimate vision is to expand and clean up our documentation for installing/running otw-archive, offering tech support for new instances of the software (and ourchive when it releases!), eventually culminating in server space we can offer similar to Walter at Squidge.org. Walter's been carrying a lot of the non-OTW side of the fandom on his shoulders for a long time as we've lost more and more independent commuities; another org working in tandem with Squidge (and indeed OTW!) would only be good for fandom.

Boldly Writing is a non-membership model nonprofit, but you're more than welcome to be a part of the organization via volunteering. Right now, we're possibly looking for a fifth board member -- or more! We can have several! -- for fiscal year 2025. A board member's main responsibilities are just to show up for the four annual meetings required by us, propose and/or vote on resolutions and bylaws and whatnot, and otherwise support the org. Terms are three years. If you're interested in this, you have to be a US citizen and over 18, but that's basically it.

Other things, like committees and assignments, are next on our agenda. (Those can be a lot of fun, too!) Currently, our Boldly Writing discussion takes place on Ad Astra's server, though we might eventually make a new one for the org.

Whilst duking it out with depression, I decided to build a new iconset for the CFAArchive, update the Underage warning to Underage Sexual Content and to add three new relationship tags. So, now the CFAA has the following relationship tags available: F/F, F/M, Gen, M/M, Multi, NB/F, NB/M, NB/NB, Other, QPR and vs.

I made the iconset myself; anyone is welcome to use them on an otw-archive install or a userskin, though they are pretty CFAA themed, just drop me credit somewhere in some obscure corner if you do use them for public consumption!

@uuuuutan's and my newest project. XD I haven't dealt with the OTW/AO3 branding in full yet, but it's coming along. It would be the #4 indie archive to run otw-a, after SquidgeWorld, superlove and Ad Astra.
