   Thanks! Tools like DomLoggerpp are super interesting for browser security work. I’ve worked in this area too (e.g., https://github.com/fcavallarin/domdig ). Wirebrowser comes at it from a different angle - no instrument

   Replay is really impressive - having a record/replay runtime that can capture all the inputs to the JS engine and reproduce execution deterministically is in a completely different category from what CDP exposes. That’s what enables tr

   Thanks! JavaScript snapshots make this feasible because the runtime exposes a complete object graph — types, edges, arrays, strings, everything. Doing similar work in C++ is on a totally different level: raw memory, no type info, pointer ch

   Good point - in theory a full time-travel debugger is more powerful. The practical limitation is that time-travel for JavaScript usually requires instrumenting the code or running inside a custom record/replay environment. Today, JavaS

   Thanks! Yes - the motivation came from repeatedly switching between DevTools, Burp, and ad-hoc scripts whenever I needed to understand how an object ended up in the heap. Wirebrowser started as an experiment to unify those workflows and mak

   Thank you! And thanks for opening the issue - handling very large memory objects is definitely an area of improvement for Wirebrowser. It’s something I plan to harden as the tool matures. Good point about the video ;) I’ll surface it more p
