Have you tried using vims :Termdebug? By default it's GDB but you can use rr or others inside of it. Just like anything else in vim you can extend it to fit your workflow. It has some rough edges sure but I'm using it successfully with C and Rust. If you have tried but still don't like it what's your use-case?
