Put your spare internet to work — safely.
Cash Raven lets you share a small slice of your unused bandwidth to help power the open web. You opt in on first launch, you can turn it off any time, and fair limits keep your device running smoothly. No account needed — just download and start.

Beta note: this build isn't code-signed yet, so Windows Defender / SmartScreen may flag it as a virus — a false positive for a new unsigned app, not a real threat. Choose More info → Run anyway. We're signing it during beta, which removes the warning.
macOS
Apple silicon & Intel · .dmg
First‑launch step on macOS

Built to respect your device
You opt in
Nothing is shared until you agree on the consent screen that opens the first time you run the app.
Off any time
One switch stops sharing instantly, and uninstalling removes everything.
Fair limits
Fair usage limits and multiple protections keep bandwidth, data and connections well within your device's means — it never hogs your line.
Stays in the background
A featherweight Rust core inside a strict CPU and RAM budget. It yields to whatever else you are doing rather than competing with it.
How it works
- 1Download & openGrab the app for your device above and launch it.
- 2Read & agreeThe built-in consent screen explains exactly what's shared. You're in control — agree to start, or close to walk away.
- 3Share in the backgroundThat's it. The app quietly shares a little unused bandwidth while your device is idle, and stops the moment you need it.
