We operate as a non-profit cooperative. The site itself is free software, written in Haskell (yesod) and we've also tried to stick with FLO tooling whenever possible, although we made an exception for hosting our source code, which is at https://gitlab.com/snowdrift/snowdrift
Of course, as a free software project, we suffer from the same funding issues we're trying to solve. The project is currently a 100% volunteer effort, and we're making slow (but nonzero!) progress towards our initial launch, when we start hosting our first outside projects.
One of our biggest bottlenecks right now is developer bandwidth. We have a handful of updated designs that address UX issues with the live site, and need to get them implemented -- if you know css, haskell, or both, we'd appreciate help!
I'm heading to bed now but will check in with this thread in the morning; you can also reach out on our discourse forum (<https://community.snowdrift.coop>), irc/matrix (#snowdrift on freenode; #snowdrift:matrix.org), or gitlab.
