Binsider is a terminal user interface (TUI) application for analyzing binary files, specifically designed for reverse engineering workflows. The tool combines multiple analysis capabilities into a single interactive interface, allowing users to examine ELF binaries through static analysis (sections, segments, symbols, relocations), dynamic analysis (system call tracing similar to strace/ltrace), string extraction, and hexdump visualization.

The tool provides general binary information including file metadata, permissions, and linked shared libraries, functioning similarly to stat(1) and ldd(1) commands. For static analysis, users can navigate through ELF layout components to understand binary structure. The dynamic analysis feature executes binaries and traces their system calls, signals, and execution flow in real-time.

Binsider targets reverse engineers, security researchers, and developers who need to analyze binary files. The TUI interface consolidates functionality typically requiring multiple command-line tools (strings, hexdump, objdump, strace) into a cohesive analysis environment. The tool is written in Rust and focuses specifically on ELF binary format analysis.
