xenmaster's free speech catalog
Either as havens for the deplatformed or as open source self-hosted solutions to those who don't want to put their community in the hands of the google and facebook behemoths, the following solutions are pretty much guaranteed to protect your right to say what you want, as long as you aren't saying/doing anything illegal. Content moderation is pretty lax in many of these apps and unfortunately, many attract refugees with unpopular opinions from the more conventional apps they replace, so proceed at your own risk!
NOTE: Unlike my other lists, I revisit this one to edit on a regular basis to add new better options and to remove those which are either shut down, go dark, or compromise their free-speech principles (in the case of third party services).

Privacy Services (WIP)
some privacy services. mostly taken from https://github.com/pluja/awesome-privacy, but I also take other suggestions.
Notunderscore's (mostly open-source) recommendations
We sometimes had no idea what to install / what programs to have, and while this list may cover some programs that may be useless to some people, I hope you find it useful anyway.

Comments and Reviews
Really great VOIP app with the lowest latency out there. As for the voice quality, it uses the same codex as TeamSpeak, so it's really not practical to compare them in that department.
Also, it's important to talk about the persistent chat functionality or lack thereof. I really don't think that Mumble will benefit from having a proper chat system in place, since the majority of its users use it for the ability to provide low latency voice comms, not for the ability to chat with each other, since users probably already have an ability to do so using other platforms (and probably even better). It would be nice to have a chat history in Mumble, but I don't think that it will benefit a lot of people.
As for security and privacy, it is the best app that you can find out there. With transparent and publicly available code, it's the only thing that you can use with a peace of mind that you are in control of your data and where it goes. The ACL's in this app are incredible, with all the fine tuning that you can possibly think of all available out of the box.
The clients for this app are awesome, working perfectly without any crashes or menus that you don't understand because you didn't read the docs enough. It's unofficial Android client is fine, although don't expect the same latency as on PC (it's on average about 100 or so ms higher, but don't take my word on that).
Overall, the ability to setup servers without any licensing bullshit, changing weird settings or dealing with proprietary software is what we need in every VOIP app.
they have completely switched to a proprietary license
Nope, in 2025 is still a very slight variant of the 3 clause BSD license. The slight variation is stupid since it makes it formally not a BSD license but there are no practical differences.
But the source code? https://github.com/mumble-voip/mumble I disagree yet.
It's still usable but it gets buggier and buggier for years now. At least on Linux.
It was a great app/server if you needed low-latency while keeping audio quality high.
Unfortunately, it looks like development of their server on Linux has halted (at time of writing, 1.5x is available on Windows/OSx yet their linux server is still stuck in the 1.3x branch).
As of 10/2025, server and client are the same version on all platforms (all v1.5.735)
Sadly there's not much point to a text chat app that clears all record of text between logins.
As far as voice goes, Mumble works on par with Teamspeak - just it's totally useless for literally anything else. This is not an alternative, it is a significant downgrade.
Last major update 2016-12-23, development has moved elsewhere
Not true since a long time, last commit yesterday. The devs are really active. https://github.com/mumble-voip/mumble
Mumble isn't discontinued. There is major development happening to bring a major new version to a stable release. The Guthub repository for this project has activity as of yesterday, March 29, 2019.
I like the fact that I can self-host the application if I want major privacy or I can purchase hosting from someone else.
Indeed, it continues to be actively developed. It's June 8th, 2021, and the last commit was yesterday. Issues on GitHub are being posted, replied to, and even closed (after being addressed). I'd venture to say that it is anything but discontinued, rather the contrary!
Also, people continue to be coming up with new tools, plugins, and so forth. For instance, on the server side (where you have to install murmurto connect all the Mumble clients), in spite of the official wiki listing many side-projects as being 'discontinued', they're actually being actively developed! Take a look at Grumble (Murmur server rewritten in Go) or uMurmur (a tiny, Qt-less version of Murmur, written in C without the overhead, designed for embedded systems with a small footprint). Both are listed as 'discontinued', or 'incomplete', but that's not correct either; they might just be lagging in certain more complex features which might not be completely developed (or not at all — yet!).
That said, it seems that the Mumble/Murmur community continues to be as committed to this FOSS VoIP platform in 2021 as they were in 2010.
