WinDbg Web

A browser-based, WinDbg-styled viewer for Windows crash dump (.dmp) files. It is not the real Microsoft debugger — it is an independent tool that parses the dump binary format directly in your browser (nothing is uploaded anywhere) and reproduces a subset of WinDbg's command output from the data structurally present in the file.

Two formats are supported: user-mode minidumps ("MDMP", from app crashes/Task Manager/WER) — loaded modules, threads, register context, exception record, captured memory ranges; and kernel/full BSOD dumps ("PAGEDUMP"/"PAGEDU64") — bugcheck code/arguments and the faulting processor's registers always come straight from the header, while the driver list and stack walk additionally require this dump to be a "Full" dump (so its physical memory is present to translate virtual addresses via page tables).

Stack traces beyond the topmost frame are a best-effort reconstruction (frame-pointer chain on x86, heuristic stack scan on x64) since full unwinding requires PDBs/unwind metadata that dumps don't contain. Disassembly and type dumping are unavailable for the same reason: the file has no code bytes or symbol information.
