Current is a native macOS BitTorrent client built around one insight: torrenting is mostly a background activity. The most useful interface is not a permanently-open dashboard — it's excellent background automation, glanceable activity, and fast intervention when something needs you.
So Current is quiet when nothing is happening, informative when something is happening, and delightful when you interact with it.
It draws its own window chrome and every one of its own controls. There is no
NavigationSplitView, no toolbar, no stock switches — not for novelty, but
because those are precisely the things that make an app look like a stock Mac
utility, and none of them can be restyled far enough to stop.

A magnet asks two questions, once Click a link and a card appears at the top of the library: what it is, how big, which files, and where it should go — with the option to remember that answer and never be asked again. |

Everything you'd reach for, without opening the app Click the menu bar icon for combined speeds, every active transfer's progress, and a pause button on each one. It's a real panel, not a menu — a list of commands couldn't draw any of this. |

- The magnet flow — click a magnet link and a card at the top of the library acknowledges it ("Resolving magnet…"), grows into the file summary when metadata arrives, and hands off to live progress the moment you press Download 8.3 GB. One continuous interaction instead of three dialogs, and it happens in the window, where the library it's about already is.
- Smart Seed — four plain-language policies (Balanced, Helpful, Archive, Temporary). Helpful mode keeps rare torrents alive even after their goal is met. Every automated decision is explained in the Rules tab: why did this happen?
- Smart Cleanup — set a storage budget; Current ranks completed downloads by how safely they can go. Eligibility is a strict safety gate (complete + seed goals met + not pinned + not active + healthy swarm); ranking then puts old, large, inactive content first. Cleanup moves files to the Trash — always reversible, never destructive by default.
- Swarm health in plain words — "Only a few complete sources are available. Keeping this torrent seeded helps preserve it." Never shame, never nag.
- Keyboard-first —
⌘Nadd magnet ·␣pause/resume ·⌘⌫remove ·⌘Fsearch ·⌘Kcommand palette · arrows/⇧/⌘ for selection. - Menu bar panel — click the icon and a panel drops under it with combined speeds, every active transfer's progress, and a pause button on each one. Everything you'd reach for without opening the app, and nothing else.
- You choose where each download goes — the confirm card offers a folder before anything starts, and remembers it if you say so. After that they go straight there, and the switch to start asking again is in Settings beside the folder itself.
- Private by construction — no accounts, no analytics, no tracking. Torrent history stays local.
Requirements: macOS 26+, Apple Silicon, Xcode 26+, Homebrew.
Package.swift currently hardcodes Homebrew's Apple Silicon prefix
(/opt/homebrew), so an Intel Mac needs it edited before anything compiles.
