Bosun is a native macOS menu bar app that shows you everything your Mac has open to the network, right when you need it, with no Terminal digging required.

It runs lsof in the background to list every listening port, then goes further than a simple port scanner: it maps each port to the process actually holding it, and adds context most tools miss.

What it shows you: - Every listening port, grouped by process, with PID, binary path, and working directory - Active ngrok and Cloudflare tunnels (named + quick), with the public URL inline - Native macOS VPN connection status - Docker containers, mapped by container name and image instead of a generic docker-proxy PID - SSH -L port forwards, parsed automatically - Per-process CPU, memory, and uptime on demand - Persistent port history with configurable retention

What it lets you do: - Kill any process with one click (graceful SIGTERM, SIGKILL fallback if it lingers) - Kill All with confirmation, for clearing out a cluttered dev environment fast - Copy localhost:PORT or open it in the browser instantly - Toggle everything from a configurable global hotkey

Bosun is built for developers running local dev servers, Docker containers, and tunnels day to day, who need to know instantly what's bound to which port, what's exposing their machine to the network, and what's safe to kill.

Pure Swift, no Electron, no third-party dependencies beyond Sparkle for auto-updates. One-time purchase, 14-day free trial, no subscription.

Analysis of Bosun.dev

Overall verdict

  • Bosun is a solid, mature open-source monitoring and alerting system built by Stack Exchange, offering powerful and flexible alert definitions, but it has a steep learning curve and has seen slower development activity in recent years compared to newer observability tools.

Why this product is good

  • Highly expressive alert scripting language allowing complex, conditional alerting logic beyond simple threshold checks
  • Built-in support for reducing alert fatigue through smart notification handling, silencing, and templating of alert messages
  • Native integrations with Graphite, OpenTSDB, Elasticsearch, and other time-series backends
  • Includes a built-in expression testing and graphing UI to validate alert rules before deploying them
  • Proven at scale, having been developed and battle-tested internally at Stack Exchange/Stack Overflow
  • Open source and self-hostable, giving full control over data and infrastructure

Recommended for

  • Organizations already using OpenTSDB or Graphite as their metrics backend
  • Teams that need highly customized, condition-based alerting rules rather than simple threshold alerts
  • Engineers comfortable writing and maintaining alert logic in a domain-specific expression language
  • Companies wanting a self-hosted, open-source alternative to commercial alerting platforms
  • Ops teams who value alert deduplication and templating to reduce noise and false positives

Questions & Answers

As answered by people managing StatusCake and Bosun.dev.

Which are the primary technologies used for building your product?

Bosun.dev's answer:

Swift 5.9+, SwiftUI + AppKit (NSStatusItem), lsof for port scanning, Sparkle for auto-updates, Polar for licensing/payments. No Electron, no third-party dependencies beyond Sparkle.

How would you describe the primary audience of your product?

Bosun.dev's answer:

Developers who run local dev servers, Docker containers, and tunnels (ngrok/Cloudflare) daily and need instant visibility into what's bound to which port, without opening Terminal or Activity Monitor.

What makes your product unique?

Bosun.dev's answer:

Bosun is the only menu bar tool that unifies port scanning with network context: it maps ngrok/Cloudflare tunnels, native VPN status, Docker containers, and SSH -L forwards to the process actually holding each port, then lets you kill it in one click. Most alternatives only do one of those things.

Why should a person choose your product over its competitors?

Bosun.dev's answer:

iStat Menus monitors the system but not tunnels or containers. Little Snitch blocks connections but doesn't show you what's already running. Seeports comes closest (port scanning for Docker/K8s/dev servers) but lacks tunnel and VPN detection. Bosun covers all of it natively, with zero third-party dependencies, no Electron overhead, and a one-time price instead of a subscription.

What's the story behind your product?

Bosun.dev's answer:

Built out of a personal need: constantly losing track of which local dev server, Docker container, or forgotten tunnel was holding a port, and resorting to lsof in Terminal every time. Bosun turns that into a native, always-visible menu bar view.
