- Programs written in esolangs.
- Short and sweet, one-file interpreters for esolangs.
- Zips, .tar.gz files, etc. If your esolang interpreter/compiler is a whole project, it's probably better to create your own repo for it and link there from the Esolangs.org wiki. I know we have some archives here, but the practice dates to a pre-GitHub era, and I would like to not add more of these.
