​@Gloriaofc  It’s an interesting question, I haven’t found any limits yet to the number of integrations!   I believe it’s not limited and there really isn’t any performance issues in my experience, I’ve installed and tried hundreds of extensions for testing and production use cases as someone consulting other teams in addition to my own use cases for my company using it.  

There may be some things to consider depending on if some apps or integrations may change how things work or data that’s integrated but things should play well together.  

Hope this helps!
