Sometimes, setting up a dedicated server installation is not feasible. The desktop application ships with a fully functional server instance by default.

For security reasons, this feature is not enabled by default. To enable it, enable Network access in Security.

After enabling network access and restarting the application, you can access this web interface locally by navigating to http://localhost:37840/login.

Mobile interface

By default, this will display the desktop user interface, even on mobile. To switch to the mobile version, simply go to the Global menu and select “Switch to the mobile version”.

Allowing the port externally on Windows with Windows Defender Firewall

First, find out the IP of your desktop server by running ipconfig in your local terminal. Then try accessing http://<ip>:37840/login on another device. If it doesn't work, then most likely the port is blocked by your operating system's firewall.

If you use Windows Defender Firewall:

1. Go to Windows's start menu and look for “Windows Defender Firewall with Advanced Security”.
2. Go to “Inbound Rules” on the left tree, and select “New Rule” in the “Actions” sidebar on the right.
3. Select “Port” and press “Next”.
4. Type in 37840 in the “Specific local ports” section and then press “Next”.
5. Leave “Allow the connection” checked and press “Next”.
6. Configure the networks to apply to (check all if unsure) and then press “Next”.
7. Add an appropriate name to the rule (e.g. “Trilium Notes”) and press “Finish”.
