GoatCounter works great, has a free hosted plan and is open source (and you can self-host it). You can export all your data, manage privacy settings, manage users and so on. Made in Go.

I’m happy it helped.
I tried many systems (paperless and it’s derivatives as well) and I found docspell is a lot easier to use and has all the features I need.

• I can archive emails by moving them to a category and docspell converts it to pdf and saves it to the database.
• I can choose a file system storage or a database storage. I chose database storage (Postgres, which is also the default) because is a lot easier to backup)
• I love the way I can categorize the files by adding recipient and sender. That way I can filter all the files related to a specific person.
• I can export all the files in a filter to a zip file.
• I can batch edit.

That as a summary :)

My only recommendations are

• to deploy it using a tag in docker and not using automatically the latest version. That way you are in control of the updates.
• And always do database backups :) (using a tag in docker means you can always redeploy a specific version.

I use docspell and I find it great. I run it on VM on an old microserver running proxmox.

There is also Mayan edms based on Django, but it has to many features for my use case.

My experience with openSuse Tumbleweed has been mostly great so far.

I’ve used linux the last 20+ years (Debian, Ubuntu, manjaro, elementary os, fedora and so on).

For me the best ones so far have been Debian and Ubuntu server edition (for servers), Linux mint and openSuse (for desktop use).

I tried openSuse because I didn’t want to upgrade my system every 6 months (for Ubuntu) nor every many years (for Debian). I like the idea of having a stable main desktop system which I can rely on and it just works. I’m hoping openSuse Tumbleweed is that system.

I’ve used primarily openSuse with KDE on my main machine the last year and I’ve had the folllowing issues:

• some VPN connections do not work but the same one does work without problems on Linux mint. (For example the Fritz-box VPN) I’m still researching this.
• most tutorials are made for Ubuntu and other distros, so you have to search a bit more to find answers. (I’ve written a few on my site) You need more time and knowledge to do some stuff on openSuse, because the defaults are more secure (or less permissive). For example sharing a folder on a network or adding a network printer means configuring the firewall rules, which on Linux mint, Ubuntu and many others is not required (which also means that the required ports are open and the required packages are pre installed).

What I’ve liked

• there defaults are more secure and that means I’ve learned what some apps need and I’ve understand a little bit how they work.
• zypper dup is great and I love having a rolling distribution. (I also love apt-get btw)
• I feel openSuse is more stable (as a desktop, I haven’t tried it on servers yet) although I don’t have any basis to say that. I have another machine with linux mint and I feel I have more problems with stability there. (Again, this is just a feeling)

I’m using this with Nextcloud through WebDAV.

There is a keepass app in Nextcloud to access your keepass database using a web browser (keeweb), keepassXC has a client for Linux, Mac and windows (and all of them work great) and there are many apps for iOS and android.

I use the free version of Strongbox with WebDAV and I haven’t had any problems.

You can just backup the keepass database file and you can also have several databases. Each database has its own password.
