Europe’s Open-Source Solutions: Your Guide to Transparent, Independent and GDPR-Aligned Software.
This guide is designed for anyone looking to take greater control of their digital life by choosing open-source solutions developed and maintained within Europe. It highlights projects that promote transparency, reduce reliance on non-European tech ecosystems, and align with Europe’s strong commitment to privacy and data protection. The goal is to support digital autonomy in Europe while uplifting the local developers and communities who build trustworthy, user-centric software.
Open-Source Slopware
A list of open-source software containing slop (LLM generated) code or endorses the usage of LLMs in other ways.
This list contains software that obviously accepts irresponsible coding practices or promotes LLM usage. I found these applications while searching for alternatives to previously used software that turned out to contain code generated by slop-machines.
Each of added applications have at least one link that points to the verifiable proof.
This list by no means is meant to cover all the software that contains code by not-so-intelligent tools and people using them but to serve as a reminder to myself about what I have already checked.
Why having LLM generated code (and using generative tools in general) is bad?
Ethical reasons — such as illegally retrieved training material, underpaid workers that prepare the training data.
Impact on environment — increased fossil fuel usage to supply the needed electricity power, water usage in water scarce regions. This somewhat overlaps with the above.
Social impact – noise pollution in neighbourhoods near AI data centres, air pollution from diesel- or gas-powered turbines (also overlaps with the above), resource consumption by data centres drastically increases utility prices.
Impact on brain and thinking, reasoning — by offloading thinking and decision making to machines people are shooting in their foot (more like in their head) as this leads to brain rot. Less intelligent people are easier to control.
Even legal issues (especially in open-source software as it cannot be guaranteed that the “generated” code is not really just re-used, thus unknowingly violating the source license).
Inevitable enshittification — every software product from big technology eventually gets enshittified to maximize revenue. For users this could mean hidden or plain ads, biased opinions/information, privacy violations, increased prices for LLM based tools.
Burden on open-source software maintenance — LLM tools provide easier access to code contributions which often shifts the responsibility of checking code quality from developers to maintainers and reviewers. Digging through walls of merge request text and code generated by slop-machines takes valuable time that otherwise could be spent more meaningfully by fixing bugs and working on new features.
I will try to add links that back up the claims above, but it may take a while.
Of course, I see how and where generative tools could be helpful and sometimes I feel tempted to find an acceptable way to use them, but for now the direct and indirect costs far too much outweigh gains.
This list has its positive counterpart: Slop-Free (Supposedly) Open-Source Software (not quite complete yet).
Also take a look at and give thumbs up to AI Slopfree Software Catalog which contains software dedicated against usage of LLMs.
Also, here is a list of some labels that can be added / voted for so they would eventually appear on application pages:
Slopware;
Slop (LLM) Code;
Slop-Source Software;
Open-Source Slopware;
Contains Slop (LLM Generated) Code.
Privacy Services (WIP)
some privacy services. mostly taken from https://github.com/pluja/awesome-privacy, but I also take other suggestions.















Comments and Reviews
An e-mail client with user experience upgraded to the 21st century and end-to-end encryption. Backward compatible with classic unencrypted e-mail.
Finally uses sensible encryption-on defaults. For best results use a dedicated account to chat
Like XMPP email is federated. Unlike feddiverse the bitchmade cannot click a button to disable your free speech. Win.
MANY paid email providers still behind on dns rr hinting for autoconfiguration. In this respect DreamHost is retarded.
whatsapp but good. encryption, all the core features... and games?? i mean why not? overall, yes, it's very quick, super straightforward, and of course, self-hostable and open-source!
The best app I've used to date
Is Delta Chat compatible with SMS text messaging? In other words, can I send and receive messages to and from phones that do not have Delta Chat installed? The FAQ does not mention SMS, and the homepage says that Delta Chat works via email.

DeltaChat is an email client with a chat-client interface and built-in encryption. It's like Spike, but free and open-source.
Relies on the network any mail-server. Therefor no need of centralized server structure. When you have several email addresses on servers which have its own management, you get away with a fairly redundant communication app.
