What it does
FlyCrys is a native Linux desktop client for Claude Code, written in Rust with GTK4. It includes a file tree, a syntax-highlighted viewer, a markdown preview, an embedded terminal and streaming agent chat. It uses your own Claude Code CLI. Development has stopped, since Anthropic now offers an official Claude Desktop app for Linux.
