There are multiple web interface for rTorrent like the most known ruTorrent. But all these alternatives haven’t a good UI. Here comes Flood, A modern web UI for rTorrent with a Node.js backend and React frontend.

The project is still work-in-progress but it’s already usable and features are added frequently.

You can find their Github here and more screenshots :

Installation have been tested on 17.04 and 20.04.

1. Install rTorrent

The easiest way is to install it from the repo, run:

2. Configure rTorrent

We need to create a dedicated user to avoid running rTorrent with root:

Now we will create a configuration file :

and copy the following:

# Where rTorrent saves the session
session = /srv/torrent/.session
# Which ports rTorrent can use (Make sure to open them in your router)
port_range = 50000-50000
port_random = no
# Check the hash after the end of the download
check_hash = yes
# Enable DHT (for torrents without trackers)
dht = auto
dht_port = 6881
peer_exchange = yes
# Authorize UDP trackers
use_udp_trackers = yes
# Enable encryption when possible
encryption = allow_incoming,try_outgoing,enable_retry
# SCGI port, used to communicate with Flood
scgi_port =

You can customize the downloads path

If you haven’t created the folders (download and session), you need to do it :

mkdir /srv/torrent/downloadsmkdir /srv/torrent/.session

And set the permissions

chown rtorrent:rtorrent -R /srv/torrentchown rtorrent:rtorrent /home/rtorrent/.rtorrent.rc

Then we need to create a systemd startup service to launch rTorrent at boot

And add to the file :

ExecStart=/usr/bin/screen -d -m -fa -S rtorrent /usr/bin/rtorrent
ExecStop=/usr/bin/killall -w -s 2 /usr/bin/rtorrent

Then enable it at boot and start it :

systemctl start rtorrent

3. Install Flood

You need first to install Node.js :

sudo apt-get install -y nodejs

if you don’t have Curl installed :

Then clone their repo:

git clone

if you don’t have Git installed :

We need to copy the template config file:

cp config.template.js config.js

Then install Flood :

4. Start Flood

Before lauching flood we will create a systemD to lauch Flood at startup ( easier to start , stop )

Create a dedicated user to run Flood:

Add permissions

Then create the script :

and copy this:

ExecStart=/usr/bin/npm start

Enable it at boot and start it:

5. Testing

You should now can access it with http://YourIP:3000

Finally it will ask you to create a user/password.

Fill the rTorrent address and port with the one you put in .rtorrent.rc at scgi_port and 5000 for me.

Congratulation ! Flood with rTorrent is installed :)
