Built, run, and debugged before you see a diff.

ByteAsk uses your compiler, your sanitizers, gdb, and your tests. You review a change that already ran.

Live debugging

It joins the gdb session you already have open.

Linux allows one debugger per process. ByteAsk uses a bridge you start in yours.
