macOS still doesn't let you control the volume of individual apps. If Spotify is loud, Zoom's ringtone hits you at the same level. SonicFlow is a free, open-source menu bar app that gives you an independent volume slider for every app currently making sound. Plus auto-ducking: when someone speaks on a Zoom or Teams call, your music automatically lowers.
Built in Swift 6 with CoreAudio Process Taps (the new low-level API Apple shipped in macOS 14.2). Under 1% CPU, MIT licensed.
Most Mac network monitors are either dashboards without outage history, enterprise tools that look like 2010, or Speedtest which hasn't shipped an update in 3+ years.
Pulse is what I wanted instead. It lives in your menu bar with a glanceable pulsing indicator and your live ping. The window has a status hero, a latency chart with two hosts side-by-side, throughput chart, network info card, and an outage timeline.
Built because every existing tool annoyed me in some specific way. Free forever.
