This is a simple web app that I made to search for public information on Brazilian companies. The site is in Portuguese and in order to see most of the info you have to create an account.

I built this to test the limits of what a server in my house is capable of handling, compared to hosting on AWS/GCP/Azure.

The service runs using 2 VMs on proxmox, one for caddy, one for the service itself, built using Go + Echo + SQLite
