Machines don't speak Java, Python, or JavaScript — they speak native binary.
High-level languages were invented for humans, not machines. Every line of Python or Java you write gets compiled down to the binary that the CPU actually executes. The native code is the real code. Everything else is a translation.
With AI agents, you can now write native binary directly — the way machines actually think. No compiler, no runtime, no abstraction layers. Just raw instructions the CPU understands.
bin2prev bridges the gap: write native with your agent, then preview it in your preferred language — Java, JavaScript, Python, Ruby, Go — so you can read what the machine already understands.
Write native. Preview human.

- Open — Double-click any binary file, or right-click → "bin2prev: Preview Binary as Source Code"
- Analyze — Parses Mach-O/ELF headers, decodes ARM64 instructions, detects syscalls
- Preview — Shows equivalent code in 6 tabs: Raw Binary, Java, JavaScript, Python, Ruby, Go
🚀 Install
- Open VS Code
- Go to Extensions (
Cmd+Shift+Xon Mac /Ctrl+Shift+Xon Windows/Linux) - Search for
bin2prev - Click Install
That's it — you're ready to preview binaries.
🎯 Usage
Open a binary
Just double-click any binary file in VS Code's explorer — bin2prev opens it automatically with a raw hex view and language preview tabs.
Right-click menu
Right-click any file → "bin2prev: Preview Binary as Source Code"
Command palette
Cmd+Shift+P → type "bin2prev" → select "Preview Binary as Source Code"
🔍 Supported Formats
| Binary Format | Instruction Set | Syscalls Detected |
|---|---|---|
| Mach-O 64-bit | ARM64 (MOVZ, ADR, SVC) | write, read, exit |
| Mach-O 32-bit | — (string fallback) | — |
| ELF 32/64-bit | — (string fallback) | — |
| PE (Windows) | — (string fallback) | — |
🌐 Preview Languages
- Raw Binary — Hex dump with ASCII view (default)
- Java — Equivalent Java source code
- JavaScript — Node.js equivalent
- Python — Python 3 equivalent
- Ruby — Ruby equivalent
- Go — Go equivalent
💡 The Vision
High-level languages exist for developers — not for machines. Machines understand native binary. With AI agents, developers can now write native code directly and use bin2prev to preview it in whatever language they're most comfortable reading.
Write native. Preview human.
