Netforge

What it does

A free offline-first desktop network multi-tool for engineers - combining MTR, LAN scanning, DNS/SSL/port diagnostics, switch discovery, subnet calculators, SNMP, speed testing, and an SSH terminal with encrypted vault, for Windows, macOS and Linux.

A free, offline desktop multi-tool for network engineers - path analysis, switch discovery, an encrypted terminal, and IP calculators in one app.

Netforge brings continuous path analysis, Layer 2 switch discovery, IP and subnet calculators, and an encrypted terminal into a single desktop app. No account, no subscription, and nothing leaves your machine. It replaces PuTTY, WinMTR, and LDWin, plus the ad-heavy web calculators you keep bookmarked. Download and use it for nothing. No subscription, no paywall, no ads, and no tracking. Calculations, scans, and the credential vault all run locally. Nothing leaves your machine. The vault is sealed with Argon2 key derivation and AES-GCM encryption. Built on Tauri 2 and Rust, so the installer is 5 to 10 MB rather than the hundreds an Electron app ships. It opens instantly and stays light on…from purple.ai

  PingStalker – A macOS tool for network engineersNov 2025 · pingstalker.com · ▲77

  Hi HN - I’m the developer of PingStalker, a macOS utility I built to see what’s really happening on the LAN/WLAN. I live in the CLI, but when it came to discovery and monitoring, I found it limiting. So I built a GUI that brings my favorite tools together in one place. PingStalker started because I wanted to know if something on the network was scanning my machine. I also wanted quick access to core details—external IP, Wi-Fi data, and local topology. Then I wanted more: fast, reliable scans using ARP tables and ICMP. As a Wi-Fi engineer, I couldn’t stop there. I kept adding ways to…

  Clipto MCP▲655

  Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

  Simple algorithm and color space to generate diverse skin tones▲627

  Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
