Deployment on Windows

Seq is a log server that runs on a central machine. Your application uses a logging library like Serilog or Microsoft.Extensions.Logging to send structured log events to Seq's HTTP API, which stores them and makes them searchable through Seq's web interface.

1. Download the Seq installer

Download the latest Seq .msi from the Seq website.

2. Install Seq

Launching the installer will start the Setup Wizard:

Seq Setup Wizard

Step through each page of the wizard. Once the installer has finished copying files, choose to start the Seq service.

Unless you've installed Seq previously, this will open the Seq Service Administration dialog and you'll be prompted for a location to store Seq's data files, and a URL to host the user interface and HTTP API. Choose the defaults if you're unsure.


It's important to set an administrator username and password for Seq when prompted.

After the service is configured, browse the Seq UI at http://localhost:5341.
