This is a terminal-based hex editor written in Rust — the kind of small, focused systems tool that makes for a fantastic learning project and a genuinely useful daily driver. Hex editors are essential for anyone working close to the metal: firmware reverse engineers, binary format hackers, CTF players, embedded developers, and folks debugging file corruption or binary protocols.
Why this one catches my eye:
- Rust + TUI is a sweet spot. Rust's memory safety and zero-cost abstractions are perfect for a tool that pokes at raw bytes. You get the speed of C with none of the buffer-overflow footguns — which is somewhat ironic and delightful for a program designed to manipulate arbitrary binary data.
- Terminal-first means it works everywhere. No GUI dependencies, no Electron bloat. SSH into a server, fix a corrupted header, log out. That's the workflow.
- Small projects teach the most. Reading the source of a hex editor exposes you to file I/O, terminal rendering, cursor state machines, undo/redo design, and binary search/seek logic — a tiny tour of systems programming fundamentals.
Who should care:
- Rust learners looking for a real-world project to study or contribute to — TUI apps are an underrated category for honing your skills beyond toy CLIs.
- Security researchers and reverse engineers who live in the terminal and want a lightweight alternative to
xxd piped through vim, or heavier tools like hexyl + bvi.
- Embedded and firmware developers who frequently inspect binary blobs, ROM dumps, or memory snapshots over SSH.
Zero stars means zero opinions yet — which makes this a great moment to clone it, try it on a real file, and offer the author early feedback or a first PR. Tiny tools with clear scope are exactly where new contributors can make a visible difference.
