Reverse Proxy

This guide outlines how to set up a reverse proxy for Plausible CE using Caddy, Nginx, or Apache. It assumes you arrived here from the quickstart guide.

Note: Starting from version 2.1.2, a reverse proxy is no longer necessary since Plausible CE can handle HTTPS and automatic Let's Encrypt certificates as outlined in the quickstart. The Nginx and Apache configurations provided here have been contributed by the community and have not been tested by the maintainers.

Expose Plausible

To allow the reverse proxy to communicate with Plausible, set the HTTP port on which you want Plausible to listen:

$ echo "HTTP_PORT=8000" >> .env

$ cat .env
BASE_URL=https://plausible.example.com
SECRET_KEY_BASE=As0fZsJlUpuFYSthRjT5Yflg/NlxkFKPRro72xMLXF8yInZ60s6xGGXYVqml+XN1
HTTP_PORT=8000

And modify the compose.override.yml file to expose that port to the host:

$ cat > compose.override.yml << EOF
services:
  plausible:
    ports:
      - 127.0.0.1:8000:${HTTP_PORT}
EOF

And then launch and sanity-check it:

$ docker compose up -d
$ curl --head http://localhost:8000
HTTP/1.1 200 OK
...

Caddy

Caddy automatically manages HTTPS and WebSockets with minimal configuration. Here’s a sample Caddyfile setup:

plausible.example.com {
    reverse_proxy localhost:8000
}

Replace plausible.example.com with your actual domain name, which should match the $BASE_URL

Save this configuration in a file named Caddyfile, and then run Caddy with:

$ caddy run --config /path/to/Caddyfile

Nginx

For Nginx, use the following server block configuration:

server {
    server_name plausible.example.com;

    listen 80;
    listen [::]:80;

    location / {
        proxy_pass http://127.0.0.1:8000;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }

    location = /live/websocket {
        proxy_pass http://127.0.0.1:8000;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "Upgrade";
    }
}

Replace plausible.example.com with your actual domain name, matching the $BASE_URL

To enable this configuration:

1. Save the configuration to a file named plausible in your Nginx configuration directory.

2. Create a symbolic link in the sites-enabled directory:

   $ cp /path/to/plausible /etc/nginx/sites-available/
   $ ln -s /etc/nginx/sites-available/plausible /etc/nginx/sites-enabled/plausible

3. Restart Nginx:

   $ systemctl restart nginx

Apache

For Apache, use the following configuration in your plausible.conf file:

<VirtualHost *:80>
    ServerAdmin [email protected]
    ServerName plausible.example.com

    ProxyPreserveHost On
    ProxyAddHeaders On
    ProxyPassMatch ^/(live/websocket)$  ws://localhost:8000/$1
    ProxyPass / http://localhost:8000/
    ProxyPassReverse / http://localhost:8000/

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

Replace plausible.example.com with your actual domain name, which should match the $BASE_URL

Follow these steps to set it up:

1. Enable the necessary Apache modules:

   $ a2enmod proxy proxy_http proxy_ajp remoteip headers proxy_wstunnel
   $ systemctl restart apache2

2. Copy the configuration to Apache’s configuration folder:

   $ cp /path/to/plausible.conf /etc/apache2/sites-available/
   $ a2ensite plausible.conf
   $ systemctl restart apache2
