Using both Flutter and React?

I have a self-hosted install using v5.5.70. It’s loaded up with roughly 10,000 clients and 20,000 invoices.

The Flutter front end is struggling to keep up and the performance is only getting worse. The React front end is snappy, but was found to be missing some important pieces. Is it possible to run both front ends simultaneously? I could see having two instances with a shared database, but the setting seems to be database-side too.

I’d also be interested in any general performance improvement tips for the Flutter front end.

Thank you!

@Standard

What is missing from react?
