Download one app. It detects your installed AI tools and routes them through Flux on macOS, Windows, and Linux.

The models FluxRouter exposes, how they are grouped into tier lanes, and how to target a specific model or let flux-auto choose.

How flux-auto routes each request, what the three pricing lanes cost, pay-as-you-go billing, and the transparency headers that show which model answered.

How FluxRouter billing works: pay-as-you-go pricing by the routed lane, plans and what's included, the Free plan, spend ceilings, usage and invoices, and what an HTTP 402 means.

Fix the most common FluxRouter problems fast: connection errors, error codes, truncated output, latency, and finding which model answered.

How FluxRouter handles your data, your API key, and your security questions: what Flux is, what it does and does not do with your requests, key handling best practices, acceptable use, and where to check live status.
