About:
Bunster is a Go-based tool that compiles shell scripts into single, statically linked binaries. By embedding the necessary shell interpreter and script content into one executable, it enables secure distribution and execution in environments without shell dependencies. This approach enhances portability and protects the original source code.

Key Features:

Compiles shell scripts to standalone binaries
Supports multiple shells (bash, sh, zsh)
Static linking for maximum portability
Obfuscates source code within the binary

Use Cases:

Distributing proprietary automation scripts without exposing source code
Deploying scripts to minimal or secure environments lacking a shell
Creating self-contained CLI tools from shell scripts

Alternatives:

shc – A classic shell script compiler, but can be less portable and more easily reverse-engineered than Bunster.
Docker – Packages applications with dependencies but is much heavier than a single static binary.
