About Bosun.dev and StackBlitz

In their own words, as submitted to SaaSHub.

Bosun.dev
StackBlitz

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...

Features and specs

What each product offers, as listed by its team.

Bosun.dev 14 features
StackBlitz 6 features
  • Port Scanning
    Detects all listening TCP/UDP ports in real time via lsof, no manual terminal digging.
  • One Click Kill
    Terminate any process by port with SIGTERM→SIGKILL fallback; Kill All with confirmation.
  • Menubar Native App
    Lives in the macOS menu bar, zero dock clutter, instant popover access.
  • Port Range Filtering
    Monitor custom ranges (e.g. 3000-9999) and exclude noisy system ports.
  • Tunnel Detection
    Auto-detects ngrok and Cloudflare tunnels (named + quick), shows public URL inline.
  • Docker Awareness
    Maps docker-proxy PIDs to container name + image instead of generic process names.
  • VPN Status Indicator
    Shows active native macOS VPN connections (IKEv2/L2TP/IPSec) at a glance.
  • SSH Tunnel Detection
    Identifies -L port-forwarding rules and displays the remote target.
  • Port History
    Logs first-seen/last-seen per port with configurable retention.
  • Process Info Panel
    CPU, memory, uptime, full command args per process on expand.
  • Global hotkey
    Configurable shortcut to toggle the popover from anywhere.
  • New Port Notifications
    System alert when a new port opens (skips the first scan).
  • Copy and Open
    One click to copy localhost:PORT or open it in the browser.
  • Auto updates
    Sparkle-based updates, EdDSA-signed, no manual reinstalls.
  • Speed
    StackBlitz is known for its quick load times and fast editing capabilities, making it ideal for rapid development and testing.
  • Ease of Use
    The interface is intuitive and user-friendly, allowing developers to get started quickly without a steep learning curve.
  • Zero-Setup
    Users can write, compile, and run code directly in the browser without any setup or configuration required.
  • Integrations
    StackBlitz integrates seamlessly with GitHub, allowing for easy import and export of repositories.
  • WebContainers
    StackBlitz uses WebContainers to run Node.js applications in the browser, providing a near-native development experience.
  • Collaboration
    Real-time collaboration features allow multiple users to work on the same project simultaneously, similar to Google Docs.

Possible disadvantages

  • Limited Plugins
    Unlike traditional IDEs like VSCode or IntelliJ, StackBlitz has a limited ecosystem of plugins and extensions.
  • Online Dependency
    StackBlitz requires an internet connection to function, which can be a limitation for developers who need to work offline.
  • Performance
    For very large projects or those requiring extensive computational resources, performance may degrade compared to local development environments.
  • Mobile Accessibility
    While StackBlitz is accessible on mobile devices, the user experience is not as optimized as it is on desktop browsers.
  • Limited Framework Support
    Although StackBlitz supports many popular frameworks, it doesn't support all frameworks or versions, which could be limiting for some projects.
  • Storage and Persistence
    Files and data are stored in the cloud, which might raise concerns around data privacy and persistence for some users.

Analysis

An editorial look at what each product does well and who it suits.

Bosun.dev
StackBlitz

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 Bosun.dev and StackBlitz.

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.
