Hex Editor is a focused tool for inspecting and editing binary data without the usual friction that comes from heavyweight desktop tooling. It is built for real analysis work: understanding file structure, validating assumptions, and making precise byte-level changes when that is the only way to solve the problem.
There is a particular kind of debugging where logs are useless, abstractions are in the way, and you need to look directly at the bytes. That is the space this project serves. It keeps the interface clear, so the data is the centre of attention rather than the tool itself.
With a reliable hex view and direct editing workflow, you can test hypotheses quickly. Is the header malformed? Is the offset table wrong? Is that checksum region where you think it is? Questions like these become straightforward to answer when inspection is fast and navigation is predictable.
It is also useful as a teaching tool for low-level thinking. Working at byte level exposes how formats are actually built, which tends to make higher-level development decisions sharper. Once you see how fragile some assumptions are on disk, you write safer code above it.
Good engineering often depends on being able to drop below the abstraction layer confidently. Hex Editor exists to make that transition immediate. It is practical, direct, and designed for people who care about correctness when the details matter.
