Have not used Sigrok, but it looks promising ..
maybe someone having operational experience can comment.

Sigrok is open source, appears to support a plethora of hardware
https://sigrok.org/wiki/Supported_hardware
The list appears quite long ..

It appears to have different protocol decoders, like the Saleae Logic
https://sigrok.org/blog/

Hmm.. It does support the Salea hardware too.. Interesting
