Pryde

Honestly this was more of a project to practice my Fsharp skills but I reckon there'd be some sort of use case for others so I've left it public.

Pryde is a self-hosted metrics API for your windows devices. It includes CPU, disk, memory, GPU and network information exposed over one local HTTP API.

Setup

1. Navigate to the releases page and download & extract the zip file to a location of your choice.
2. Run install.ps1 in powershell.

• If prompted by user account control, click yes, the installer requires admin privileges to register the windows service (and its also required to read from the temperature sensors)

3. Once finished, Pryde sits in C:/Pryde and will run as a Windows Service. It will now start automatically every time the machine boots so you don't need to keep a terminal open.
4. You can confirm if it works by opening https://localhost:5000/system/cpu in a browser, you should be able to see the json output with your CPU usage, name and temperature.

Managing the service

Pryde runs as a standard Windows Service named Pryde, so it can be managed the same was as any other service.

Start-Service Pryde  #start
Stop-Service Pryde  #stop
Restart-Service Pryde #retart
Get-Service Pryde #status

Via the services app: Open services.msc, find Pryde in the list, and use the Start/Stop/Restart buttons or right-click menu.

Uninstalling

Run uninstall.ps1 as Administrator (from the original releases folder. This stops the service and removes it from Windows.

Endpoints

Endpoint	Description
GET /system/cpu	CPU usage, core count, name, temperature
GET /system/disk	Per-drive space and filesystem info
GET /system/graphics	GPU name, driver, VRAM, temperature, load
GET /system/uptime	System uptime since last boot
GET /network/throughput	Per-adapter upload/download rates
GET /network/port/{port}	Whether a specific TCP port is currently listening

All endpoints return JSON and require no authentication in this version — Pryde is intended to run on localhost or be reached only over a private network (e.g. Tailscale). See Exposing this remotely below before opening it up any further than that.

Exposing this remotely

By default, Pryde only answers requests reaching it directly — it does not open any ports on your router or make itself reachable from the internet on its own. If you want to check on your device while away from home, I'd reccomend doing this over a virtual private netowrk (vpn) or by using a tunnel instead of port forwarding, this can be done using a service like Tailscale or using a Cloudflare tunnel.

A note on admin privileges

Pryde runs under the LocalSystem account so it can read CPU temperature sensors, which requires elevated access on Windows. This means the service runs with full system privileges. If you don't need temperature monitoring and would rather run with reduced privileges, you can change the service's logon account via services.msc → Pryde → Properties → Log On - CPU (and GPU) temperature will simply come back empty in that case, everything else will keep working normally.

Building from source

dotnet publish src/Pryde.Api -c Release -r win-x64 --self-contained true -p:PublishSingleFile=true

The resulting Pryde.Api.exe will be under src/Pryde.Api/bin/Release/net9.0/win-x64/publish/. Copy it alongside install.ps1 and uninstall.ps1 to reproduce a release package.
