Why

Splitwise is one of the best apps to add expenses and bills.

I understand that every app needs to make money, After all, lots of effort has been put into Spliwise. My main problem is how they implemented this.

Making pro features or asking money to remove ads is fine, But asking money for adding Expenses (Core feature) is frustrating.

I was searching for other open-source alternatives (Let's be honest, any closed-source product might do the same and I don't have any reason to believe otherwise).

I managed to find a good app spliit.app by Sebastien Castiel but it's not a complete replacement and didn't suit my workflow sadly. Check it out to see if it fits you.

That's when I decided to work on this

Nginx Guide for RedHat based systems (Fedora, RHEL, CentOS etc)

Add a new conf file to your nginx configuration for this application

Validate the new config

sudo nginx -t

If everything looks good, you can go ahead and restart nginx to reflect the new config (You can also reload it but I prefer restart)
