Before downloading
See the files
before spending bandwidth.
Paste a magnet with Ctrl+V or open a .torrent: Zerem shows the file list first and warns you if it will not fit on the disk. Pick what to download — and change your mind any time.
- "Fetch this first" for the file you want now
- A watched folder picks up .torrent files on its own
- Categories, each with its own folder
Everything a torrent client needs.
And nothing that weighs it down.
A cap on active downloads — and seeding does not count toward it.
A stuck torrent tells you why in plain words, not an error code.
Your normal limits and a slower second set, switched from the footer or on a schedule.
DHT, UPnP, IPv6, uTP, encryption and SOCKS5 proxy.
The country of each peer, without asking anything outside your computer.
Speaks the qBittorrent API, off by default and local only.
At a share ratio or after a number of hours, and move files when done.
Remappable shortcuts, screen-reader labels throughout and columns your way.
Every update is checked against a signature before it replaces the program.

Questions
How much does it cost?+
Nothing. Zerem is free and open source (GPLv3), with no ads and no account.
Do I need admin rights?+
No. On Windows it installs just for your user. On Linux there is a .deb, a PKGBUILD for Arch and an installer that goes into your home folder without root.
Does it have search or RSS?+
No, on purpose. Zerem downloads what you give it and does that well — finding torrents stays with the site you already use.
Does it work with private trackers?+
It depends on the tracker. Some only accept a list of known clients and may refuse Zerem.
Does it keep downloading with the window closed?+
Yes. It sits in the tray, spending no CPU on drawing, and downloads carry on.
Download more, wait less.
