all-in-one

https://nextcloud.com/office/ seems to be exactly that. Self hosting seems to consist of "set up nextcloud, set up collabora, click the integration button" https://nextcloud.com/blog/how-to-install-nextcloud-office/ Or just `sudo docker run --init --sig-proxy=false --name nextcloud-aio-mastercontainer --restart always --publish 80:80 --publish 8080:8080 --publish 8443:8443 --volume nextcloud_aio_mastercontainer:/mnt/docker-aio-config --volume /var/run/docker.sock:/var/run/docker.sock:ro ghcr.io/nextcloud-releases/all-in-one:latest` if you follow these instructions: https://github.com/nextcloud/all-in-one

Kinda. I use managed Nextcloud by Hetzner (StorageShare) for ~20 people with their smallest instance (1TB, 4.50 EUR/month) and connected it with a Collabora hosted on the smallest Hetzner VPS (this could use more cores). If you wanna self-host completly look at https://github.com/nextcloud/all-in-one . I have this running on my NAS for other stuff, but it just works out of the box. Edit: and it scales. Orgs with a lot more people use it for 10k users or more. And it doesn't need a 100 EUR/month setup, from what I experienced.

[Atomic](https://github.com/nextcloud-atomic) is being designed as the single machine successor to [Nextcloudpi](https://github.com/nextcloud/nextcloudpi). It is a system-level wrapper for [Nextcloud All-in-One](https://github.com/nextcloud/all-in-one). All about the development and lessons learned over the last 6+ years. Other guest is the developer of Nextcloud Bookmarks, Floccus.

NextCloud on a VPS works very well for me. The AIO setup does all the work for you: https://github.com/nextcloud/all-in-one
