Port Detective Pro

What it does

Every Windows developer knows the "port already in use" headache. Port Detective Pro is a fast, native-Rust app that shows you exactly which process owns any TCP/UDP port, lets you kill it in one safe click, and then guards your critical ports in the background so nothing hijacks them again.

Port Detective for Windows: find what process is using a port and kill it safely. Port Detective Pro adds Port Guard, remote scans, Docker mapping, and connection history. Free core edition plus a one-time Pro purchase.

Port Detective is a native-Rust Windows app that turns `EADDRINUSE: address already in use` into a one-click fix. The free edition shows what is listening, who owns it, and includes 5 free kills to try safe termination. Port Detective Pro unlocks unlimited kills plus the active layer: a background Port Guard watchdog, remote and Docker-aware scans, deep process inspection, and exportable connection history — one purchase, fully unlocked, no subscription. Everything in Free, plus Port Guard, remote & Docker scans, process inspection, history export, and the Ctrl+K palette. Live port viewer, instant lookup, and 5 free kills to try safe termination — the daily EADDRINUSE finder. `netstat` plus…from automatalabs.ca

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Homebrew 6.0.0▲1,481

  Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

  Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
