spreed VS appstore

> Tell me another platform that is free, has realtime chat, voice and video, has stable service, allows sharing images and other media, with good ownership management... and is open source.

Mattermost: https://mattermost.com/

Rocket.Chat: https://www.rocket.chat/

Nextcloud Talk: https://nextcloud.com/talk/

Self hosting and some assembly required. I've run all of them on cheap VPSes to explore a Slack/Discord replacement, neither was mindblowing but all of them seemed okay (Nextcloud's offering was rather barebones, though).

Audio and video support varies because getting those right is challenging, at best you'd just integrate with something like Jitsi, that one's actually pretty good for meetings and such: https://jitsi.org/ and has a cloud version too: https://meet.jit.si/ (yet people still go for Zoom and it's odd UI/UX choices)

I actually rather liked forums back in the day, but I guess nobody will be setting up that many phpBB instances in the current year, though projects like Discourse also seem promising: https://www.discourse.org/

I don't think many people at all will be leaving Discord, due to how entrenched the platform is (network effect): if you want people to help you with what you're working on, you go where they are, not vice versa.

To add to this, it's reasonably easy to run, and has many different plugins, from a calendar and contacts list, to an online document editor (like Google Docs, except it can be pretty slow and/or resource intensive: https://nextcloud.com/office/), to a simple clone of Slack (https://nextcloud.com/talk/), a mail client (https://apps.nextcloud.com/apps/mail) and other things.

That said, I've had updates (across major versions) break things on multiple occasions, one out of two servers running the exact same version has random crashes and in addition to that the file locking by default (if enabled, but not using Redis: https://docs.nextcloud.com/server/latest/admin_manual/config...) has broken and prevents me from deleting a file that just sits there and takes up a few GB of space. Oh and their Android app fails to upload files if I use the share option, instead of the file picker from within the app.

On the other hand, sure beats storing data on third party clouds and is free, so I'll still keep using it.

> The calendar app is very functional and allows booking of appointments based on availability similar to Calendly. This is one of many apps within its large and expanding suite.

Another noteworthy one is Talk: https://nextcloud.com/talk/

It's not quite as good as something like a self-hosted instance of Mattermost or even Rocket.Chat, but honestly if you already have Nextcloud, then it's pretty cool to be able to get something decent like that up and running quickly.

Ofc that's making Nextcloud a single point of failure in some ways and occasionally things can go sideways with these plugin based platforms (historically applies more to installs of Jenkins, but also have had some performance issues with Nextcloud that had lots of apps, too).

I still rather like Nextcloud because of being able to just run it on my servers and replace a bunch of other third party cloud platforms and still somehow manage to have good enough uptime and security.

Internal chat/communication

Nextcloud Talk (version 15.0.3): Have private video calls and chat using your own server.

Nextcloud Talk

Nextcloud has a chat app https://nextcloud.com/talk/

Nextcloud with the Talk extension can do exactly what you are looking for! https://nextcloud.com/talk/

I have good news for you: https://apps.nextcloud.com

Nextcloud is nothing more than a collection of small apps. You can disable even core things like sharing.

Anyway, I'm sure you would have found this by using your favourite search engine. Nextcloud is pretty popular. And you'll find much more integrations on the Nextcloud app page or on /r/nextcloud.

Nextcloud allows us to keep our personal files in sync across devices. I use it to sync files between my desktop, laptop, and phone. This means I can work on the same file from anywhere. I leverage a separate file server to store backups, installation kits, legacy documents, iso files, roms, and other things that I want to keep, but do not need direct and immediate access to on the regular. Nextcloud is purpose built. You can access your files through an installed client or through its web interface. Nextcloud has a lot of add-on apps as well which can really extend its functionality. Nextcloud also has an "instant upload" feature which uploads your photos from your phone to your Nextcloud instance. This can be very helpful as it is easier for me to view/edit photos from my desktop. You can also share files between users on the same Nextcloud instance. it's very similar to Dropbox or Google Drive, except you can host it yourself and keep your data, your data.

It is overkill for this only, but if you want to host many more small services like this easily, you may be interested in Nextcloud. Once you have it, you can add any app available on https://apps.nextcloud.com/ with one button, in particular the bookmark app. Bookmarks can then be synced to your browser with the open-source addon https://floccus.org/

Can you reach https://apps.nextcloud.com/ from your network?

By default it does the usual expected things like file and photo syncing, notes, calendar, contacts, to-do lists, etc. Because it's open source, it can be extended by other people who make "apps" for it that you can install, of which you can see an exhaustive list here. Notable entries include office software, password managers, RSS readers, chat services, and plenty more.

Like KDE, Gnome, and Nextcloud?

Nextcloud has support for far more features than just file serving if you look at all these apps.

I agree with you. It seems like the self-hosting community is getting a decent amount of attention right now, and the ability to deploy browser-based applications is the way to go for many FOSS projects.

I think NextCloud [0] has a few apps that do G Suite-type stuff, but I don't have experience using them. Etherpad [1] also seems really good, I've used it in a few Zoom calls and the experience was smooth.
