In addition to the command-line tool sigrok-cli, the following GUIs are currently being worked on (neither are fully usable or released yet, though):
- PulseView (Qt based) — currently the best choice, supports logic analyzers and has initial analog support
- sigrok-qt (Qt based) — work in progress, currently not usable
- sigrok-gtk (GTK+ based) — work in progress, has limited (but working) logic analyzer support
We're happy if other people write further GUIs or special-purpose frontends for their own specific needs, that was one of the reasons to structure sigrok into shared libraries after all.
