FlyCrys

FlyCrys
## ⚠️ No longer actively developed
On June 30, 2026 Anthropic released an official Claude Desktop app for Linux
(download · docs),
covering Ubuntu and Debian on x64 and arm64 with the same Chat, Cowork and Claude Code
experience as macOS and Windows.
FlyCrys existed because there was no native Linux GUI for Claude Code. Now there is one,
built by the people who make Claude Code itself. There is no point in maintaining a copy
and competing with the original, so development has stopped.
The repository stays online as an archive: the code still builds and the last release still
works, but expect no new features, no bug fixes and no support. If you are here looking for
a Linux desktop for Claude, use the official app.
Thanks to everyone who starred, filed issues and sent patches.

Native Linux GUI for Claude Code agents. One binary, starts in under a second, no Electron.

Why this exists

I've used Linux exclusively for 30 years. When Claude Code became my daily driver for writing software, the terminal worked but I kept hitting walls: can't preview images, can't see a file tree while the agent works, can't render markdown without switching to a browser, can't juggle multiple project streams without a mess of terminal tabs.

I didn't want Cursor or anything Electron-based. I wanted something native that feels like it belongs on a GTK desktop.

FlyCrys is not an IDE. It doesn't edit files. Agents do. You talk to agents, they write the code. FlyCrys gives you a workspace to manage that workflow: file tree on the left, viewer in the middle, agent chat on the right, terminal at the bottom. That's it.

What makes it different

- Native Linux GUI for Claude Code — Opcode uses webview; when FlyCrys started, Claude Desktop skipped Linux entirely (it no longer does — see…
