REA

Reverse Engineer Apps is a desktop application for examining executables, libraries and other binary files without running them. It gives developers, security researchers, IT staff and students a clear graphical way to see what a file is made of. Pick a file and the app identifies its format, shows its metadata, calculates its SHA-256 hash, displays the hexadecimal header, extracts readable ASCII strings with their offsets, and measures byte entropy to help spot packed or encrypted data. Results can be exported as a JSON report. Your files stay on your computer. Local inspection works offline, and the app never executes a file just to inspect it. Nothing you inspect is uploaded unless you explicitly choose to send it somewhere. Deeper analysis features, such as running the full REA engine, project history and optional AI-assisted analysis, are still being developed and are not part of this description until they are finished and tested. Try the full app free for 3 days. After that, a one-time payment unlocks it for good on up to 2 of your devices. Open Source Acknowledgement Reverse Engineer Apps is developed and distributed by G Thompson / Niagara Indie Apps. It incorporates software from REA (Reverse Engineer Anything), an open-source project developed by morluto and its contributors. Original repository: https://github.com/morluto/rea The original REA software is licensed under the MIT License. Copyright (c) 2026 morluto. The original REA developers retain their respective rights to their contributions. Niagara Indie Apps independently develops and maintains the desktop application and its original components. Niagara Indie Apps is not affiliated with or endorsed by the original REA project. The complete original licence and the notices for other components are inside the app, in the About section under Open source credits. Optional Ghidra analysis For a deeper look, the app can use Ghidra, the free reverse-engineering suite from the U.S. National Security Agency, to count the functions and strings in a program and list its memory sections. The file is only read, never run, and nothing is uploaded. Ghidra and Java are separate programs and are not included: the Windows setup asks before it installs them, and on Linux and macOS the app asks the first time you open it.
