There's an official Golang rewrite called dendrite: https://github.com/element-hq/dendrite it has few start because they recentyl migrated it from the original repo (https://github.com/matrix-org/dendrite) Development is not fast but it's going on, and it's currently on beta. I haven't tried it, I selfhost a synapse server which I used with friends, and with docker it wasn't hard to set up/maintain after the initial effort.

Only the Apache-licensed version is dead. The commercial arm (Element) forked it and relicensed it under the AGPL to make sure nobody but them can use their post-fork changes commercially. (Element demands you sign a CLA to contribute. Don’t[1].)

Very easy to set up (without the Docker nonsense, it's just a binary that is trivial to build), but the real work was in maintaining it. After the third case of database table inconsistencies from joining large public rooms (or perhaps from upgrading it, or a combination) I regretfully had to give up on it. It was time consuming to find out the table structure being used and how to manually correct the data so that it would start again. People were generally helpful on irc but it's just not fun work and feels a bit unnecessary.
