Latest
- HTTP Traffic Monitor — Captures and displays all HTTP and HTTPS requests from a Windows machine, showing the sending app and per-phase timing, with replay, compare and mock features.“My side project: a free HTTPS traffic inspector for Windows that AI assistants can drive”
- Network Doctor — Diagnoses network connectivity by checking DNS, TCP, TLS, HTTP, proxies, routing and path MTU, and explains where a connection fails.“I used AI coding agents extensively to build a real network diagnostic CLI. My rule: prove every bug before fixing it”
- Shows each network connection a Mac makes, including the remote source of incoming packets and other networking details.“Built a Network monitor tool that shows each and every connection your mac makes.”
- Snitch — Visualizes the network connections a computer makes, showing which processes contact which hosts.“I built Snitch — a local-first network traffic visualizer that shows every hidden connection your computer makes (open-source, zero telemetry)”
- Porter — Lists local network ports with their status and owning process, and lets the user close processes holding a port.“Porter: Open Source Cross Platform Port Manager”
- netwatch — Monitors network interfaces, routing, connections and per-process network activity in a terminal UI.“netwatch (terminal network monitor, Rust) now runs natively on FreeBSD”
- Checks Ethernet link, DHCP, DNS and internet connectivity on a handheld device with a display.“I built a pocket LAN tester. Is a more capable version worth building?”
- Signal — Analyzes nearby Wi-Fi networks, channel congestion, speed, ping and local network devices on an Android phone.“I built a free Wi-Fi analyzer”
- WiFi Heatmap 3D — Maps Wi-Fi signal strength across a floor plan as a 2D or 3D heatmap from readings taken around the home.“Your router probably isn’t the problem — your room might be”
- Red — Points a custom domain or subdomain at a self-hosted service's underlying address, such as a Tailscale hostname with a port.“I built a tiny service because I got tired of ugly URLs and IP addresses”
- tunnl.gg — Exposes a localhost port to the public internet over HTTPS using a plain SSH reverse tunnel.“tunnl.gg: a free, open source ngrok alternative that runs on plain ssh (no install, no account)”
- QuickStream Speedtest — Measures internet download and upload speed from a browser extension popup.“I built a lightweight speedtest extension because I was tired of bloated websites. Would love your feedback!”
- tunr — Exposes a local port through a public HTTPS link and can deploy apps to a hosted URL that sleeps when idle.“Started as "let me see my students' projects live", ended up as a tunnel + tiny host: tunr”
- MyIPSpot — Shows a visitor's IP address with map, IPv6 and VPN leak tests, DNS lookup, and HTTP header details without cookies or tracking.“I got tired of every "what's my IP" site being an ad-stuffed tracker, so I built a tracker-free one”
- HOTS Hosts — Edits the Windows hosts file with parental controls, a privacy/telemetry blocking module, and malware diagnostics.“Built two versions of a hosts file editor (full + lite) — curious which one people actually prefer”
- NetLens — Overlays wifi diagnostic information onto the camera view using augmented reality.“I made this...again! - NetLens for iPhone”
- NetGuardian Pro — Monitors network connections on Windows, scores suspicious addresses, blocks them via Windows Firewall, and explains alerts in plain language.“Built a Windows network monitor that explains what's happening in plain English instead of dumping connection tables on you”
- Cuniculum — Provides a GUI for importing, saving and connecting OpenVPN, L2TP/IPsec and PPTP profiles through NetworkManager on Arch Linux.“I built a small VPN manager for Arch because I was tired of doing everything manually”
- Ntercept — Captures and analyzes HTTP/HTTPS traffic from a chosen browser tab, with search, filtering, JSON viewing and request comparison.“I Built Ntercept: A Browser Extension for HTTP/HTTPS Traffic Analysis ✌️”
- TinyNetUse — Displays live network download and upload speeds in a movable, resizable desktop overlay with an optional history graph.“I wanted a tiny network speed display on Windows, so I made one”
