Hey Product Hunt! 👋 I’m Justin, the maker of Throttlr. I started building Throttlr after repeatedly running into two frustrating situations: sometimes one Mac app would quietly consume most of my connection, and other times my internet would suddenly feel slow but I couldn’t tell which app was causing it. Most network monitors could show me traffic, and firewalls could stop an app completely, but I wanted something in between: quickly find the app responsible, limit just that app, and let everything else keep working normally. Throttlr lets you: - Monitor live upload and download activity by app - Set separate upload and download limits - Block an app’s traffic when needed - Apply controls to individual apps or to the whole system’s internet and local network traffic - See how speeds have changed over the last five minutes The part I’m most excited about is how immediate it feels: set a limit, toggle throttling, and watch the app settle at that speed. Privacy was also important to me. Traffic contents, browsing activity, and per-app network statistics stay on your Mac. Throttlr requires macOS 15 or newer. It’s distributed as a signed and notarized package and uses a macOS network system extension, which macOS asks you to approve during setup. There’s a free monitoring tier, and every new installation includes a 14-day Pro trial without an account or credit card. Thanks for checking it out—I’ll be here throughout the launch to answer questions and hear your ideas.
