The native download manager, on your machine
The desktop client draws its interface on the GPU with GPUI — the framework behind Zed — and drives a Rust download engine running in its own background service. Free and open source.
Preview builds are pre-releases (vX.Y.Z-rc.N) for early adopters. Desktop, Android, server and CLI ship on this channel; each is rebuilt only when it changes, so versions can differ. Browser extensions stay on stable.
Free · open source · AGPL-3.0
Visitors in mainland China download through our Aliyun CDN mirror; everyone else downloads from GitHub. If the mirror doesn't have the file yet, it falls back to GitHub automatically. You can also use the GitHub backup link.

FluxDown Server is the engine without a desktop: a self-hosted web UI you reach from any browser, for home servers, NAS boxes and routers.
Docker
One container, amd64 and arm64.
Then open http://localhost:17800 — on first launch you set your own access key (8+ characters, letters and digits).

CLI docsAndroid
APK builds per CPU ABI. Not sure which one? Take the universal build. Upgrading from the old Flutter-based app: the new app is signed with a new certificate, so uninstall the old one first (this clears its local data).
