WinMTR merges ping and traceroute into a single Windows diagnostic tool, showing packet loss and latency for each hop in a live table. It is a portable green build and released as open source under GPL v2.

A desktop front end for the InterPlanetary File System that folds a local node, file handling, peer management and content browsing into one application. If a node already runs on the machine it becomes the control panel for it instead of starting a second one. Version 0.50.1, MIT licensed, three desktop platforms.

An open source project that links phones and computers over one protocol. Files and links pass either way, phone notifications arrive on the desktop and can be answered from there, and one device can trigger a predefined command on another. Clients exist for every major platform.

Nmap is a free open source tool for network discovery and security auditing, answering which hosts on a subnet are up, which ports are open and what runs behind them, with Zenmap, Ncat, Ndiff and Nping in the same package.

Transmission is a free open source BitTorrent client known for very low memory and processor use, with native interfaces on three platforms, a daemon of its own and web remote control; stable version 4.1.3 fixes security flaws.

Dozens of storage backends behind a single vocabulary, plus two abilities that change what is possible: encrypt before uploading, and mount any cloud drive as a local disk.

A rewrite that throws out the old stack, ships as one executable and keeps the parts that matter: desktop and mobile sync, sharing links, and a deployment that fits on a page of instructions instead of a runbook.

Remote access with the trust chain kept in house: RustDesk is fully open source, works out of the box on a public relay, and lets you stand up your own relay so traffic never leaves your machine. Five platforms, encrypted sessions, free for personal use.

A browser download bar loses everything when the line drops and never fills the pipe. Free Download Manager splits a file into parallel streams, resumes where it stopped, and carries a full torrent engine in the same list.

An embedded engineer spends the morning on a serial port and the afternoon on a remote server. Tera Term puts both in one plain window: baud rate, data bits and flow control in plain view for the board, key and password authentication for the server, and a macro language that turns repeated console work into one command.

Rent storage and the terms, the price and the location of the files all belong to somebody else. Nextcloud is the open source answer: sync, share links, permissions and version history on a machine you control, with calendar, contacts and document editing bolted on.

MediaMTX takes a stream in over one protocol and hands it out over another, with RTSP, RTMP, HLS and WebRTC all speaking to each other. One binary, no dependencies, small enough for a single board computer, and open source.

Seafile is an open-source file sync and sharing platform you host yourself. It organises files into libraries that sync, share and encrypt separately, transfers only changed blocks, keeps version history, and from version 13 moved to a container-based deployment.

TigerVNC 1.16 arrives with a server component for sharing Wayland desktops, a native viewer whose long-standing F8 menu has been replaced by a proper shortcut system, a searchable address history and two quick fix releases.

qBittorrent Enhanced Edition is a community branch built from the qBittorrent source. It keeps the original engine and interface and adds rules that manage connections: automatic blocking of peers that never upload, automatic refresh of public tracker lists, a temporary IP filter and peer whitelists.
