I was recently exploring the options of self hosted cloud and was quite disappointed with NextCloud. The performance of both the UI and syncing was pretty bad. I thought my home NAS just isn't powerful enough. Then I tried OCIS (golang rewrite of ownCloud) and it's a complete different story.

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?
