Seeking solution to sync wordpress sites with Server

I am searching for a solution to develop wordpress sites on my local machine via XAMPP and easily sync changes to my webhost. And with changes i mean everything, all files and the database. The only criteria i have that i dont want a subscription model.

I found a couple solutions but these are all monthly or yearly subscriptions. I am absolutely willing to pay money but i want to pay once and thats it ...

Does anybody know any Tools/Software?

Thank you very much in advance!
