The app is free and open source. Core cloud — account, sync and the like, where one server can serve thousands — is a one-time buyout. Storage-heavy services are not included and may later be sold as a subscription.
The native desktop client for macOS, Windows and Linux — a GPU-rendered UI on a Rust engine. No account needed.
Paid plans only cover cloud services — the FluxDown app itself is free and open source.
The differences are only services that run on our servers. Everything that runs locally stays fully free — no artificial limits, now or ever.
