There's no sign up with mobile phone or email, or sensible data. Only chat that works from origin to destiny via a link (or scanning a qr code).

Also you can use and configure your own server for more security, privacy and control of the messages sent in your chats.

And the app is free and open-source.

Probably the best privacy chat alternative.

I like SimpleX. It's a lightweight IM platform. Unfortunately, the image sharing quality doesn't meet my standards and the invite links drive my contacts away from using the app.

I tried it first in September 2023. It felt buggy at the time. Now in July 2024 it feels mature and dependable. Development is continous. Version 6.0 was release a few weeks ago. Use it both on my Android phone and on my Linux Desktop. The focus on privacy and anonimity remains. I foresee a promising future for this instant messenger.

I encourage you to do your own research about it ! Also while open source is great for privacy and security it is not perfect. So keep that in mind before downloading any apps. Most apps that I've listed are privacy friendly but some might be not be perfectly private and secure. I again encourage you to do your own research about them. I am not a privacy and security expert. I'm also don't consider myself as a developper so I do not have any technical knowledge and so I didn't look into any source code of any apps in this list !

Beautiful Open Source Apps for Android (nice & modern UI/UX)

UI = User Interface UX = User eXperience Most open source apps offer out-dated or classic material design UI. If the apps works great and the UX is not terrible you might find it okay. But intuitive UI are better, and modern looking ones are pleasant to use, sadly they are not the majority. Here is my list of Beautiful Open Source Apps for your android device ! Apps are listed in alphabetical order ! Also look at : The ultimate F-Droid setup for more open source android apps. and Beautiful Open Source Apps for iOS for your iOS device DISCLAIMERS Nice UI comes to personnal preference. So this list is only based on my taste of what is a good modern looking app. While open source is great for privacy and security it is not perfect. So keep that in mind before downloading any apps. I again encourage you to do your own research about them and read their Privacy Policies. I am not a privacy and security expert. I'm also don't consider myself as a developper so I do not have any technical knowledge and so I didn't look into any source code of any apps in this list !

What is SimpleX Chat?

SimpleX Chat is an encrypted, open-source messaging platform prioritizing user privacy. It uses no traditional identifiers for maximum privacy, confirmed by a security assessment by Trail of Bits in November 2022.

Features include end-to-end encryption for messages, images, and files, with message editing, replying, and deleting options. It supports encrypted audio and video calls, secret chat groups, and private notifications. Users can transfer their chat history and contacts to other devices with a portable chat profile.

The platform doesn't use identifiers, ensuring privacy of identity, profile, contacts, and metadata. It provides protection against spam and abuse, and users can only be contacted through a one-time invitation link or a temporary user address. All data is stored on client devices, with messages temporarily held on SimpleX relay servers. The platform operates on a decentralized network, enabling users to use their own servers.

Users can connect via link or QR code and start messaging without needing emails, phone numbers, or passwords. User profiles and contacts are stored in the app on the user's device, inaccessible to servers. Messages are end-to-end encrypted using the open-source double-ratchet protocol and routed via servers using the SimpleX Messaging Protocol.
