Everyday tools / OPEN-SOURCE PROJECT GUIDE
Signal
Less noise. Private conversations.
An open-source messaging app with end-to-end encrypted messages and calls, built by an independent nonprofit.
Why it matters
Makes encrypted everyday communication accessible through a straightforward messaging experience.
The honest heads-up
Your contacts need Signal too. A phone number is required to register, although usernames can help you connect without sharing it. It does not connect to WhatsApp chats.
Your first small step
Install the app and invite one person you talk to regularly.
