Browser-based PE disassembler. All analysis client-side via WebAssembly.

Live Demo

• PE Analysis — headers, sections, imports, exports, resources, authenticode signatures
• Disassembly — x86/x64 via Capstone WASM with hybrid recursive descent + linear sweep, jump arrows, minimap
• ARM64 — PE32+ ARM64 images disassemble via a fixed-width sweep, with A64-aware CFG, jump arrows and cross-references; the decompiler is x86-only and says so rather than guessing. An image whose machine type has no decoder here (ARM32/Thumb, IA-64, RISC-V, MIPS) is refused visibly instead of being decoded as x86, and still shows its headers, sections, imports, exports, resources and strings
• Decompiler — IR-based built-in decompiler with SSA, type inference, and struct synthesis; optional Ghidra server for high-level output
• Control Flow Graph — inline IDA-style graph view with collapsible blocks, keyboard navigation, and pan/zoom
• AI-Powered Analysis — chat, and enhance/explain in the decompile panel (bring your own API key)
• Kernel Driver Analysis — .sys driver detection, suspicious API flagging, IOCTL decoder, IRP dispatch table
• Annotations — bookmarks, renames, comments with undo/redo and export/import
• Cross-References — function calls, strings, imports, data section references
• Anomaly Detection — flags WX sections, packer indicators, disabled ASLR/DEP, and more
• Hex View — hex dump with data xref indicators
• Offline / PWA — installable, works fully offline after first visit
• Theming — 4 built-in themes + custom theme import/export
• MCP Server — AI agent integration via Model Context Protocol

Requires Node.js 20+.
