Deployment Notes
The easiest way to get PairDrop up and running is by using Docker.
TURN server for Internet Transfer
Beware that you have to host your own TURN server in order to enable transfers between different networks.
You can follow this guide to either install coturn directly on your system (Step 1) or deploy it via docker-compose (Step 5).
Deployment with Docker
Docker Image from Docker Hub
docker run -d --restart=unless-stopped --name=pairdrop -p 127.0.0.1:3000:3000 lscr.io/linuxserver/pairdrop
You must use a server proxy to set the X-Forwarded-For to prevent all clients from discovering each other (See #HTTP-Server).
To prevent bypassing the proxy by reaching the docker container directly,
127.0.0.1
is specified in the run command.
Options / Flags
Set options by using the following flags in the docker run
command:
Port
-p 127.0.0.1:8080:3000
Specify the port used by the docker image
- 3000 ->
-p 127.0.0.1:3000:3000
- 8080 ->
-p 127.0.0.1:8080:3000
Rate limiting requests
-e RATE_LIMIT=true
Limits clients to 1000 requests per 5 min
Websocket Fallback (for VPN)
-e WS_FALLBACK=true
Provides PairDrop to clients with an included websocket fallback if the peer to peer WebRTC connection is not available to the client.
This is not used on the official https://pairdrop.net, but you can activate it on your self-hosted instance. This is especially useful if you connect to your instance via a VPN as most VPN services block WebRTC completely in order to hide your real IP address (read more).
Warning: All traffic sent between devices using this fallback is routed through the server and therefor not peer to peer! Beware that the traffic routed via this fallback is readable by the server. Only ever use this on instances you can trust. Additionally, beware that all traffic using this fallback debits the servers data plan.
Specify STUN/TURN Servers
-e RTC_CONFIG="rtc_config.json"
Specify the STUN/TURN servers PairDrop clients use by setting
RTC_CONFIG
to a JSON file including the configuration. You can usepairdrop/rtc_config_example.json
as a starting point.To host your own TURN server you can follow this guide: https://gabrieltanner.org/blog/turn-server/
Default configuration:
{ "sdpSemantics": "unified-plan", "iceServers": [ { "urls": "stun:stun.l.google.com:19302" } ] }
Docker Image from GHCR

Deployment with Docker Compose
Here's an example docker-compose file:
version: "2"
services:
pairdrop:
image: lscr.io/linuxserver/pairdrop:latest
container_name: pairdrop
restart: unless-stopped
environment:
- PUID=1000 # UID to run the application as
- PGID=1000 # GID to run the application as
- WS_FALLBACK=false # Set to true to enable websocket fallback if the peer to peer WebRTC connection is not available to the client.

Deployment with node
git clone https://github.com/schlagmichdoch/PairDrop.git && cd PairDrop
Install all dependencies with NPM:
npm install
Start the server with:
node index.js
or
npm start
Remember to check your IP Address using your OS command to see where you can access the server.
By default, the node server listens on port 3000.
Environment variables
Port
On Unix based systems
PORT=3010 npm start
On Windows
$env:PORT=3010; npm start
Specify the port PairDrop is running on. (Default: 3000)
Specify STUN/TURN Server
On Unix based systems
RTC_CONFIG="rtc_config.json" npm start
On Windows
$env:RTC_CONFIG="rtc_config.json"; npm start
Specify the STUN/TURN servers PairDrop clients use by setting
RTC_CONFIG
to a JSON file including the configuration. You can usepairdrop/rtc_config_example.json

Default configuration:
{ "sdpSemantics": "unified-plan", "iceServers": [ { "urls": "stun:stun.l.google.com:19302" } ] }
Options / Flags
Local Run
npm start -- --localhost-only
Only allow connections from localhost.
You must use a server proxy to set the X-Forwarded-For to prevent all clients from discovering each other (See #HTTP-Server).
Use this when deploying PairDrop with node to prevent bypassing the proxy by reaching the docker container directly.
Automatic restart on error
npm start -- --auto-restart
Restarts server automatically on error
Rate limiting requests
npm start -- --rate-limit
Limits clients to 1000 requests per 5 min
Websocket Fallback (for VPN)
npm start -- --include-ws-fallback
Provides PairDrop to clients with an included websocket fallback if the peer to peer WebRTC connection is not available to the client.
This is not used on the official https://pairdrop.net, but you can activate it on your self-hosted instance. This is especially useful if you connect to your instance via a VPN as most VPN services block WebRTC completely in order to hide your real IP address (read more).
Warning: All traffic sent between devices using this fallback is routed through the server and therefor not peer to peer! Beware that the traffic routed via this fallback is readable by the server. Only ever use this on instances you can trust. Additionally, beware that all traffic using this fallback debits the servers data plan.
Production (autostart and rate-limit)
npm run start:prod
Production (autostart, rate-limit, localhost-only and websocket fallback for VPN)
npm run start:prod -- --localhost-only --include-ws-fallback
To prevent connections to the node server from bypassing the proxy server you should always use "--localhost-only" on production.
HTTP-Server
When running PairDrop, the X-Forwarded-For
header has to be set by a proxy. Otherwise, all clients will be mutually visible.
Using nginx
Allow http and https requests
server {
listen 80;
expires epoch;
location / {
proxy_connect_timeout 300;
proxy_pass http://127.0.0.1:3000;
proxy_set_header Connection "upgrade";
proxy_set_header Upgrade $http_upgrade;
proxy_set_header X-Forwarded-for $remote_addr;
}
}
server {
listen 443 ssl http2;
ssl_certificate /etc/ssl/certs/pairdrop-dev.crt;
ssl_certificate_key /etc/ssl/certs/pairdrop-dev.key;
expires epoch;
location / {
proxy_connect_timeout 300;
proxy_pass http://127.0.0.1:3000;
proxy_set_header Connection "upgrade";
proxy_set_header Upgrade $http_upgrade;
proxy_set_header X-Forwarded-for $remote_addr;
}
}
Automatic http to https redirect:
server {
listen 80;
expires epoch;
location / {
return 301 https://$host:3000$request_uri;
}
}
server {
listen 443 ssl http2;
ssl_certificate /etc/ssl/certs/pairdrop-dev.crt;
ssl_certificate_key /etc/ssl/certs/pairdrop-dev.key;
expires epoch;

docker logs pairdrop_node_1
.
Testing PWA related features
PWAs require that the app is served under a correctly set up and trusted TLS endpoint.
The nginx container creates a CA certificate and a website certificate for you. To correctly set the common name of the certificate, you need to change the FQDN environment variable in docker/fqdn.env
to the fully qualified domain name of your workstation.
If you want to test PWA features, you need to trust the CA of the certificate for your local deployment. For your convenience, you can download the crt file from http://<Your FQDN>:8080/ca.crt
. Install that certificate to the trust store of your operating system.
- On Windows, make sure to install it to the
Trusted Root Certification Authorities
store. - On macOS, double-click the installed CA certificate in
Keychain Access
, expandTrust
, and selectAlways Trust
for SSL. - Firefox uses its own trust store. To install the CA, point Firefox at
http://<Your FQDN>:8080/ca.crt
. When prompted, selectTrust this CA to identify websites
and click OK. - When using Chrome, you need to restart Chrome so it reloads the trust store (
chrome://restart
). Additionally, after installing a new cert, you need to clear the Storage (DevTools -> Application -> Clear storage -> Clear site data).
Please note that the certificates (CA and webserver cert) expire after a day. Also, whenever you restart the nginx docker, container new certificates are created.
The site is served on https://<Your FQDN>:8443
.
