Category: Advanced Hex & Text EditorVerified for 2025
Top Recommended Replacements
ImHex
FREEBest Modern FOSS Alternative
Why we like it
The closest rival to 010 Editor's power; features a custom pattern language for data parsing; modern GPU-accelerated UI; includes a built-in disassembler and node-based data processor.
Keep in mind
Steeper learning curve for its advanced 'Pattern Language' compared to 010's C-like templates; can be heavier on system resources (RAM/GPU).
HxD
FREEBest for Quick, Basic Edits
Why we like it
Virtually instant startup; handles exabyte-sized files; supports raw disk and RAM editing; completely free and very stable on Windows.
Keep in mind
Windows only; lacks a template/parsing system; no scripting or advanced data visualization capabilities.
Hex Fiend
FREEBest for macOS Performance
Why we like it
The fastest hex editor for Mac users; handles massive files with near-zero latency; features a clean, native interface; support for basic binary templates.
Keep in mind
macOS only; lacks the enterprise forensics and disk editing depth of 010 Editor.
Free Hex Editor Neo
FREEBest for Windows Large-File Work
Why we like it
High-speed performance on TB-scale files; features advanced binary diffing and a structure viewer; very modern Windows 11-native UI.
Keep in mind
The 'Free' version is limited; advanced parsing and script-based automation require the paid 'Professional' tier.
010 Editor (v16.x Personal)
Best Professional Value
Why we like it
Access to the world's largest repository of binary templates; incredibly reliable; cross-platform (Win/Mac/Linux).
Keep in mind
Strict 'Personal Use' licensing terms; high price point for non-commercial users compared to HxD.
VSCodium (Hex Extensions)
FREEBest for 'In-Editor' Checks
Why we like it
Keep your workflow inside one app; Microsoft's official Hex Editor extension is surprisingly capable; zero corporate telemetry.
Keep in mind
Lacks 'Template' parsing (data interpretation); can lag on files over 1GB due to its Electron-based core.
Binary Ninja (Free Version)
FREEBest for Reverse Engineers
Why we like it
World-class disassembly and decompilation; the visual graph view is revolutionary; powerful API for automated analysis.
Keep in mind
Overkill for simple byte manipulation; the full version is the most expensive on this list.
REHex
FREEBest Minimalist Template Editor
Why we like it
Includes a 010-inspired template language; lightweight and cross-platform; perfect for developers who need parsing without the ImHex UI overhead.
Keep in mind
Smaller community and fewer pre-made templates compared to 010 Editor.
Kaitai Struct
FREEBest for Cross-Language Parsing
Why we like it
Define a file format once in YAML and generate parsing code for 10+ languages; features an excellent Web IDE for testing structures.
Keep in mind
It is a 'library builder' rather than a traditional hex editor; requires coding knowledge to utilize the generated parsers.
HexEd.it
FREEBest for Quick Browser Edits
Why we like it
No installation required; works on tablets and Chromebooks; supports large files via browser storage APIs; surprisingly fast for a web app.
Keep in mind
Limited by browser security (cannot access raw disks or hardware memory); lacks advanced scripting/templates.
