## What it is
nnd is a fast, TUI-based debugger for Linux implemented from scratch in Rust, not based on gdb or lldb. It supports breakpoints, stepping, watch expressions, and pretty-printers for C++ and Rust, and ships as a single dependency-free executable.

## Use cases
- debug native C++ or Rust programs on Linux
- a fast terminal debugger alternative to gdb
- debug large executables with heavy debug info
- debug over ssh in a TUI
- step through code with conditional and data breakpoints

## When to choose
- you debug native code (C++, Rust, Zig, Odin) on Linux x86-64
- you want a snappy TUI debugger without gdb/lldb
- you work over ssh and want a lightweight single-binary debugger

## When to avoid
- you need ARM, macOS, or Windows support
- you need remote debugging, GUI, IDE/DAP integration, or record/replay
- you debug Java, Python, or other managed runtimes
- you need multi-process/fork-following debugging

## Facets
- artifact type: cli-tool
- maturity: maintenance
- function: developer-tools, terminal-ui
- domain: developer-tools
- platform: cli
- tags: debugger, tui, native-code, rust, x86-64, standalone-executable, command-line, linux
