How PortPeek Works
From Windows kernel TCP socket tables to your browser in under 2 milliseconds.
Engineered for Developer Velocity
Precision tools for local server orchestration.
📱 Test on Phone (QR Code)
Instantly test localhost web apps on your phone over local Wi-Fi by scanning a native vector QR code.
🌐 One-Click Public Tunnel
Bridge localhost to a temporary public Cloudflare or Ngrok URL to share live previews with clients or teammates.
⚡ Free Up Port (EADDRINUSE)
Dedicated stuck port resolver to select any port and terminate the orphaned background process holding it hostage.
⏱️ Real-Time Health & Latency
Subtle status dots and live round-trip millisecond latency meters showing if your backend is fast, slow, or hung.
📌 Port Aliases (.portpeek)
Pin and label database or microservice ports (e.g. 5432 ➔ "Postgres DB", 11434 ➔ "Ollama LLM") via workspace config.
Global Hotkey (Win+Alt+P)
Summon the PortPeek menu instantly right at your mouse cursor from inside any IDE, terminal, or full-screen app.
PortPeek talks directly to the Windows kernel. No Electron. No WebView2 runtime. No 300 MB Chromium browser running silently in the background.
