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.
DeMicrosoft Your Life
How are you?
In this list I bring you a variety of alternative software to those from Microsoft, and also that these free and open source programs
So enjoy this list!
(I will be updating it every day)
Recommended Software for the Average Joe and Jane [1/3]
Part 1 of 3 in Series: lists will continually be updated periodically.
Criteria I look for universally for my lists are as follows:
— Open source code: publicly audited
— Privacy-focus: minimal data collection, encryption by default
— Security-focus: 2FA available, encryption by default
— Zero Knowledge end-to-end encryption (E2EE) when appropriate
— Cross-platform or progressive web apps (PWAs) + cloud backup/sync
— Freemium subscription model, so basic features are always available for free
— Oligarchy / Big Tech alternative
— Absence of “dark” or deceptive patterns
Criteria specifically for this list:
— Established companies with a strong reputation
— Provides a “it just works” experience for the user: minimal configuration, user friendly
— Features available can easily replace Big Tech’s popular apps

Comments and Reviews
I am at ease with Lumo AI by Proton.
Great mascot I love it's design. However marketing it as Open Source is misleading as only the clients are. Especially how they started with words like "Unlike other AI assistants, my code is fully open source, so anyone can verify that it’s private and secure — and that we never use your data to train the model.".
But that's not my main issue with it. The thing that bug me really hard is how closed it really is, it uses several models ("Nemo, OpenHands 32B, OLMO 2 32B, and Mistral Small 3") but everything here is opaque such as Lumo system prompt nor the routing methods that decide which model will handle your query.
Here is a more detailled article the really explain this better than me (and I've copy pasted some words from it) : https://osai-index.eu/news/lumo-proton-least-open
Its very nice to use and very attractive UI
It's very solid, UI close to Mistral, although much less features. The answers it gave me were solid, but sometimes it needed veeeery long to think, like 10 minutes. But it's not buggy like other Chats (GreenPt). Also, the chat does get decrypted when it's passed into the AI model, that's something I didn't realize at the beginning. I do recommend Lumo though.
I like that they're bringing an open source and privacy friendly AI product. But it's not entirely open source. Nevertheless, it's the privacy protections and the not learning from you is the main selling point.
On that open source front, there has been improvements:
The cutoff for it's knowledge is a couple of years old. So when working as a programmer on systems that evolves frequently, I don't quite get the code/scripts that follows the typical patterns and best practices we follow in our industry. So, if you're looking for something specialised, you may want to create a project with the necessary set of instructions. But this would be limited if you try to point to llms.txt files.
Having said that, with the architectural improvements in Lumo 2.0, it's really good at searching and giving general knowledge answers. The personalisation is a nice touch, too.
gotta use it for casual thinking
I like that Proton is bringing its privacy-first philosophy to AI. Knowing that conversations aren't used for profiling or training makes Lumo an interesting alternative for anyone who regularly works with sensitive information.
