The High Performance Backend is written in Rust. > nextcloud is still a buggy php app (without swoole) and owncloud is a completely rewritten in golang. I'm just getting started with Nextcloud & did some research into the topic. My take is they are going to keep PHP due to legacy & interoperability reasons. How is the DX in making an Owncloud App? Also, are there open source alternatives to their Enterprise features, such as Microsoft integration?
