Inspect WebAssembly section tables, exported functions, memory limits, and hex bytes in-browser.
Execution runs 100% locally inside the browser sandbox using HTML5 Canvas, Web Cryptography Subtle API, and Web Workers. Zero egress.
Zero network latency. Operates completely offline with zero dependencies on third-party backend servers or cloud services.
Built according to official RFC specifications, cryptographic test vectors, and enterprise-grade data transformation standards.
Upload a compiled .wasm binary module or click 'Load Sample Module'.
Inspect the section table, memory allocations, and exported function symbols.
Review the byte-offset analysis and formatted hex dump.
It supports standard WebAssembly binary specification v1 (MVP and beyond) with standard section layouts.
No. All byte parsing and disassembly executes 100% locally in your browser memory.
