A lightweight macOS menu bar app that shows your internet speed at a glance, powered by speed.cloudflare.com.
If you're the kind of person who visits fast.com multiple times a day — after restarting your router, joining a new WiFi network, or just because something feels slow — this app saves you the trip. Your download and upload speeds are always right there in the menu bar, updating automatically on a schedule you choose.
- Real-time speed display — Download and upload speeds update live in the menu bar as tests run
- Cloudflare-powered — Uses Cloudflare's speed test endpoints directly, no slow server discovery
- Configurable display — Choose whether to show download, upload, or both in the menu bar
- Adjustable test interval — Run speed tests every 5, 10, 15, 30, or 60 minutes
- Launch on login — Optional toggle to start automatically when you log in
- Manual test — Hit "Test Now" to run a speed test on demand
- No dependencies — Pure Swift/SwiftUI, no Python or CLI tools required
