I'm building a JavaScript debugger called Wirebrowser. It combines network inspection, request rewriting, heap snapshots, and live object search.
The main experimental feature is BDHS (Breakpoint-Driven Heap Search): it hooks into the JavaScript debugger and automatically captures a heap snapshot at every pause and performs a targeted search for the value or structure of interest. This reveals the moment a value appears in memory and the user-land function responsible for creating it.
Another interesting feature is the Live Object Search: it inspects runtime objects (not just snapshots), supports regex and object similarity, and lets you patch objects directly at runtime.
Whitepaper: https://fcavallarin.github.io/wirebrowser/BDHS-Origin-Trace
Feedback very welcome, especially on whether BDHS would help your debugging workflow.
I sometimes find these tools crash hard when pushed via large memory items, huge blobs of code, long base64 strings etc. Even chrome dev tools crash hard on large WS Messages.
Also perhaps post the video near the top instead of hiding it in the origin paper :), kids like videos these days.
Good point about the video ;) I’ll surface it more prominently, the whitepaper ended up a bit dense, so having the visual demo earlier probably helps a lot.
