Sync MySQL schemas bettwen diferent databases

I have a couple of databases that have the exact same structure than my "master" database, but after a couple of months, the developers did small changes (like, add another collum, change a datatype to fix an error, etc) and they forgot to replicate it overall databases.

After some research, I found out that mysqldiff could generate the queries to update the databases left behind. But since I am using MySQL 8, it doesn’t work (ERROR: Query failed. 1146 (42S02): Table ‘mysql.proc’ doesn’t exist), and the project (mysql-utilities) looks like got abandoned (the last commit is from 2016)…

Does anyone know a free alternative for mysqldiff? I just need to sync the databases, not the data. I am asking because most questions that I looked up where a little bit old.
