Signal Foundation (nonprofit) · since 2014
Signal
Private messaging with the least leftover metadata.
Signal is the nonprofit, open-source messenger focused on privacy. Chats are end-to-end encrypted with minimal metadata.
It only works if your contacts are there. Weak as a default social network; strong as a privacy choice.
Why it's here
- Nonprofit, open source, privacy-first
- End-to-end encryption with minimal metadata
- Free on Windows and mobile
- Smaller network — worth it when friends will join
