binary-analysis

Know what's inside any Apple binary — in milliseconds. Mach-O introspection for reverse engineers, security researchers, and build engineers. Reads fat headers, symbols, sections, instruction boundaries, and direct branch edges. Zero dependencies, no build step, runs anywhere Node does.

MCP servers I built — zero-dependency, stdio, for Codex/Claude Code

Web-based interactive static pattern discovery tool to locate structures from frequent patterns

Identify a file from its bytes, not its extension, and report what is hidden: appended data after IEND or a ZIP directory, embedded script tags, a name that disagrees with the contents, near-maximum entropy.

⌘ ELF32/ELF64 binary inspector: sections, symbols, relocations, dynamic dependencies and a security report (PIE/NX/RELRO/canary) — pure JS, zero dependencies, browser + CLI.
