A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.

Rules:

  1. Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.

  2. No spam posting.

  3. Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.

  4. Don't duplicate the full text of your blog or github here. Just post the link for folks to click.

  5. Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).

  6. No trolling.

Imo, it's nice to see tools written in a memory safe systems language

Especially if you use a lot of them. More utility, less attack surface

This makes sense! You get the same advantage if the app uses Go or C# though, and both of those can compile to a single statically-linked executable too.

If it's written in C# that's a huge turn-off though because that means it's likely to only run on Windows.

I mean, in theory, it could run on Linux but that's a very rare situation. Almost everything ever written in C# uses Windows-specific APIs and basically no one installs the C# runtime on Linux anymore. It's both enormous and a pain in the ass to get working properly for any given C# project.

That's a very old way of thinking of things. C# has been cross platform for a long time.

Almost everything ever written in C# uses Windows-specific APIs

Not really. Most C# apps use .NET (since the framework and standard library is quite feature-rich) rather than direct Win32 calls, and .NET is cross-platform. A lot of web services are written in C# and deployed to Linux servers.

basically no one installs the C# runtime on Linux anymore

You can compile a C# app to a single executable that doesn't require the framework to be installed.

Are you running Jellyfin, the *arr suite, slskd, or Technitium DNS? They're all written in C#.

You've obviously never tried to get any given .NET project working in Linux. There's .NET and then there's .NET Core which is a mere subset of .NET.

Only .NET Core runs on Linux and nobody uses it. The list of .NET stuff that will actually run on .NET Core (alone) is a barren wasteland.

I'm a C# developer and run .NET apps on Linux all the time. I usually work on CLI and server apps, but recently released my first Linux desktop app written in C#: https://flathub.org/apps/com.daniel15.wcc

Even before .NET Core, I was using Mono to run C# apps on Linux. There used to be quite a few GNOME apps written in C#.

There’s .NET and then there’s .NET Core which is a mere subset of .NET.

Nope. The old .NET Framework has been deprecated for a long time. The latest version, 4.8.1, is not very different to 4.6 which was released 10 years ago.

The modern versions are just called .NET, which is what .NET Core used to be, but with much more of the framework implemented in a cross-platform way. Something like 95% of the Windows-only .NET Framework has been reimplemented in a cross-platform way.

The list of .NET stuff that will actually run on .NET Core (alone) is a barren wasteland.

All modern .NET code is built on the cross-platform framework. Only legacy apps used the old Windows-only .NET Framework.

If you get the free community version of Visual Studio and create a new C# project, it'll be using the latest cross-platform framework. You can even cross-compile for Linux on a Windows system.
