Show HN: Klisi – a GTK4/Adwaita callgrind profile viewer and generator

For a long time, I had been in search of a callgrind profile viewer that would better integrate with the GNOME desktop environment.

KCacheGrind is amazing, but I was looking for a GTK native alternative.

Recently, I took an interest in Clojure, so I decided to combine the two in one project.

The result of this is Klisi.

Try it out and let me know what you think.

You can read a small write-up about this first release on my blog[1].
