There’s nothing technically wrong with it, it’s just a glacial development speed. I tried contributing there myself when I wanted a specific feature (which had been requested years prior by someone else and was deemed a good idea), it took months before I even got a single comment back.

In the meantime, I had switched to conduwuit because it was a much, MUCH more active project. However, conduwuit has diverged substantially from conduit, including irreconcilable database changes, so it is not possible to migrate back, that would require starting from a fresh slate and loosing all user data.
