Transmission
A headless daemon does the downloading while you drive it from any browser: Transmission turns a plain server into a private download station that needs no desktop session and no seedbox subscription. Add torrents by file, magnet link, or watch directory, then follow progress, priorities, and per-file selection from the web interface. Speed rules keep transfers polite: global and per-torrent limits, ratio targets that stop seeding at the share you choose, and scheduled alternate limits for office hours. Bad-peer blocklists, peer exchange, DHT, and protocol encryption are built in, and trackers can be edited per torrent when a swarm moves. Finished downloads can be relocated automatically, incomplete files kept apart, and new torrents queued in the order you add them. The same daemon answers the transmission-remote command line and third-party remote apps over its RPC interface, so scripts can add, pause, and inspect transfers alongside the browser. It runs on modest hardware with a small memory footprint, which is why NAS vendors have shipped it for years. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. GPL-2.0 licensed.
ZNC
Your IRC networks and channels stay alive on the server around the clock under ZNC, which replays everything you missed the moment your client reconnects. Connect from your desktop, laptop, and phone at the same time, all sharing one identity and one scrollback. Each channel keeps a configurable playback buffer, so a client that reconnects after hours offline receives the conversation it missed instead of a blank window. Detach from a channel without leaving it: ZNC keeps your nick present, answers pings, and holds your place while no client is attached. Separate users on one instance each get their own networks, channels, and settings, which makes a single server a shared bouncer for a whole team or community. The web administration panel creates and edits users, networks, and global settings from a browser. The control panel module exposes the same controls through IRC commands. Modules extend the core in C++, Python, or Perl, adding everything from SASL authentication and away handling to message logging and push notifications. SSL/TLS encryption protects both the IRC connections and the web panel, with IPv6 supported alongside IPv4 on every listener. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. Apache-2.0 licensed.
