Hecate review
A focused, free terminal hex editor with interpreted views and large-file support.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Hecate is an open-source terminal hex editor for inspecting and editing binary files directly. It is aimed at terminal users, reverse-engineering workflows, and anyone who wants to work with binary data through a local command-line tool. Windows, macOS, and Linux are supported, and edits can be written back to disk in place.
Its main strength is the range of interpreted views beneath hexadecimal bytes. Integer, floating-point, text, bit-pattern, and date representations help connect raw bytes with different ways of understanding their values. Endianness and signedness toggles add control when interpreting data, while expression-based offset navigation provides a direct way to move through a file. Full-file searching, tabbed browsing, and large-file support round out the inspection workflow.
Hecate uses an open-source, free model rather than a tiered commercial plan. Vim-like keyboard navigation keeps the interaction centered on the terminal, which should appeal to users who prefer keyboard-driven tools and local file access. Its cross-platform availability makes it suitable for teams working across Windows, macOS, and Linux, while its focused scope keeps attention on binary-file inspection and editing. Choose Hecate if you want a free terminal editor with multiple data interpretations and in-place writes. Users who need a hosted service or a graphical interface should choose a different type of hex editor.
