what is redexcompile fr?

RedEXCompile is a cross-platform desktop code editor from RedX Development, built on the Monaco editor, the same editing core used by VS Code, wrapped in an original dark red and black interface. It supports its own RedEX programming language with syntax highlighting, snippets, a formatter, an outline view, diagnostics, and a preview runner, along with a plugin system called RedEXP and a public plugin registry backed by GitHub. The editor includes multiple persistent terminals with support for PowerShell, Command Prompt, Git Bash, WSL, Bash, Zsh, Fish, and other shells depending on what is installed. A Toolchain Vault discovers programming language runtimes already on your machine so they can be reused across projects instead of being copied into each one, and it can also create Python virtual environments automatically with one click. Package search across npm, PyPI, Cargo, NuGet, Maven Central, RubyGems, Composer, and pub.dev lets you install dependencies scoped to the open project. For AI assistance, you can bring your own API key from OpenAI, Anthropic, Gemini, OpenRouter, or another OpenAI-compatible provider to write, fix, explain, refactor, test, or document code from inside the editor. It also includes the official GitHub Copilot SDK agent with device login, selectable models, and streaming responses. Live collaboration lets multiple people edit the same project with shared cursors, text chat, and voice or video over WebRTC, and a phone can connect for editing either locally with a pairing code or remotely through a temporary Cloudflare tunnel. RedEXCompile ships as installers for Windows, macOS, and Linux, including a portable Windows executable, a macOS DMG, and a Linux AppImage or Debian package. To run it from source instead, you need Node.js 22 or newer, then run npm install followed by npm run dev from the folder containing package.json. Building your own distributable packages uses npm scripts such as npm run dist:win, dist:mac, and dist:linux, and the README notes that unsigned builds may trigger Windows SmartScreen or macOS Gatekeeper warnings unless the build is code-signed.
