Solo user + self hosted data source

Hi,

I've read all I can but don't think there is an option for my use case.

I'm a single user of RDM but I want to self host my data source because I use RDM from multiple devices.

I know there is the option of using the Devolutions Personal Hub (currently using). However, as my vault grows, RDM is becoming slower and slower. It's slow to make changes to entries, it's slow to launch.

I'm more than happy to pay a reasonable amount to use the application as it is very useful.

I don't have 5 users which is the next and only step up I believe. Also, $25 USD/month is way out of my budget.

Is there another paid tier or licensing option that purely just allows me to self host either via SQL or the Devolutions Server?

Thanks.
