The projects

One fox, many tools.

Why Fox Code

Tools you can actually trust.

No subscriptions by default, no data harvesting, no mystery binaries. Every Fox Code project runs on your own device and ships its full source. You stay in control of your keys, your files, and your privacy.

Open source

Read the code, build it yourself, verify every release by sha256. Nothing hidden.

Private by design

Work happens on your device. Keys are encrypted on-device; no telemetry, no accounts.

Free to use

Every project is free. Use built-in free tiers or bring your own provider key — your choice.
