Also, you can now run nREPL in your browser https://metaredux.com/posts/2026/11/01/nrepl-right-in-your-browser.html I did this mostly for the new http://nrepl.org, but I guess other people might find it useful for whatever reasons.
Glad to hear someone found it interesting. It was a fun side project for me (I wanted to make it easier and more visual how nREPL communication works), but I always realized that the audience would be quite niche. 😄
