The latest release of marketkernel/html-disasm is v0.2.0. This project is a disassembler that breaks the machine code of executables down into readable instructions. It runs offline in the browser as a single HTML file, so nothing has to be installed and no file has to be uploaded. What changed in v0.2.0 is not stated in the provided information.
It supports ARM64, ARM32, x86, x86-64, WebAssembly, .NET CIL and Java bytecode. You can open Mach-O, ELF, PE, APK and IPA files and explore their instructions, functions, references, strings and binary metadata. The files it targets come from macOS, iOS, Linux, Android and Windows. Because it handles several platforms and formats inside one file, it suits anyone who wants to look inside a binary without installing anything else. It is written in TypeScript and released under the MIT license.
The README explains that it does not upload files to a server and blocks network access with a content security policy. The provided record lists 101 source files, 101 tests and 4 commits, but nothing there indicates performance or analysis accuracy. The breadth of supported formats can therefore be confirmed, while the reliability of its actual analysis results is hard to judge from this information alone.
