Cremniy

All tools for low-level development are combined and linked in a single application — write code, edit bytes, and analyze binaries without extra windows

What is Cremniy?

Cremniy is an integrated environment for low-level development. Instead of keeping a HEX editor in one window, a disassembler in another, and a code editor in a third — all tools are combined and linked in a single convenient application.

Designed for:

• 🛠 System software developers
• 🔍 Reverse engineers
• 🔐 Cybersecurity specialists
• 📡 Embedded systems developers

Why Cremniy?

Low-level development today means using a code editor, HEX editor, disassembler, debugger, all opened in separate windows.

You constantly switch between different windows, and the tools are not linked together.

Cremniy solves this!

• 🔘 Everything is in one place
• 🔗 All tools are connected
• 💻 Unified workflow

Features ✨

Available now

Feature	Description

pacman -S --needed base-devel mingw-w64-ucrt-x86_64-toolchain mingw-w64-ucrt-x86_64-cmake mingw-w64-ucrt-x86_64-qt6-base mingw-w64-ucrt-x86_64-libgit2

3. Add MSYS2 package directory to PATH
   MSYS2 packages are located in C:\msys64\ucrt64\bin by default.

🐧 Linux (Debian-based / Fedora)

For Debian-based distributions:

sudo apt update
sudo apt install cmake g++ qt6-base-dev libgit2-dev

For Fedora:
