# When to use PropelAuth BYO

Choosing between PropelAuth BYO and PropelAuth Cloud depends on your specific needs and constraints. Here are some scenarios to help you decide:

1. **Need to own your data?**  
   PropelAuth BYO runs in your infrastructure with your database.

2. **Starting fresh or want a provider that does everything?**  
   [PropelAuth Cloud](https://docs.propelauth.com/) is a comprehensive auth solution that handles it all, and can serve as a replacement for your existing auth.

   PropelAuth BYO lets you add just the features you need.
