This is the EsoList, not the first (but probably the first on dev.to) community built list of amazing esolangs! Feel free to comment on any of these so long as the comments are constructive. Enjoy!

FreakC

FreakC is a multi-paradigm esoteric scripting language. It is written in Batch, compiled to Batch and compatible with Batch codes and libraries. It adds certain features to Batch, but with excessive cursing which makes it an esolang. It is 100% open-source on Github, and open for anyone to contribute! The language is currently at v4.9.0 and is stable.
