About this app

Berty makes privacy the easy option.

Berty is an encrypted and offline peer-to-peer messenger with NO central server. Connect with or without an internet connection, message for free, and avoid surveillance and censorship.


Berty is fresh off the development line and hasn’t been audited yet. Please keep this in mind when exchanging data.

🔐 End-to-End Encrypted Messaging

In some countries, even a lol or a like can get you sent to jail. Berty is end-to-end encrypted - not even our developers could access your data, let alone corporations or governments.

♾️ Free Forever

Privacy is a right for everyone, so Berty doesn’t profit from keeping you safe online. Created by an NGO, Berty will always be free and relies on the generous community to power development.

🌍 100% Decentralized

Just like blockchain technologies, Berty doesn’t pass your data through central servers - the place where internet service providers, hackers, and governments can intercept your data. Instead, Berty’s network is distributed, based on P2P direct messaging.

👻 Completely Anonymous

Berty couldn’t care less about who you are. You don’t need to provide your real name, an email, or a date of birth. You don’t even need a SIM card!

📱 Protect Your Metadata

You might not know what metadata is, but WhatsApp, Facebook Messenger, and WeChat all collect it. This data can reveal a lot about you - so you’ll be glad to hear Berty is a messaging app alternative that collects as little metadata as humanly possible.

📡 Communicate Without Traditional Networks

Berty is made to work in the most challenging network conditions in the solar system. If governments, hackers, or natural disasters shut down cellular or internet networks, users can still make vital instant communications over Berty’s proximity Bluetooth feature.

💬 Join Group Chats

Berty is a full-featured instant messaging app. Create groups, chat securely, and share media with friends, family, and colleagues.

🗣️ Share Voice Messages

Instantly send encrypted voice memos and audio files on Berty’s decentralized network.

🔃 Beta: Toggle Between Accounts

Create different accounts to split your messaging identities by work, school, family - however you want to categorize your messages!

The Berty messaging app, built on the Berty Protocol, is designed, developed, and deployed by French non-profit NGO, Berty Technologies.

But Berty isn’t just decentralized in terms of its architecture - it’s also owned by the community, not a corporation interested in profits. The progress of Berty relies on developers testing and feeding back on our open source code, generous funding from funds and individual donors, and online and offline advocacy in the community.

In theory (and writing), it all sounds great. It'd be awesome if all messaging app developers had the same mentality and actually strived to applying said theory and make it happen. The only relevant issue I have here, is that the app seems to take up alot of storage space. Almost 300MBs just sitting idle. So, for now, i'll pass. Thank you, though and good luck.

Comparing similar apps: Briar is much less buggy but more confusing & kind of ugly. Berty is less buggy & more intuitive than Jami. Berty & Cwtch are the most beautiful. Cwtch is less buggy than Berty but has less features & only works on android (bcuz it uses Tor). Out of all them, Berty's UI felt the most intuitive and user-friendly. If it was less buggy, I'd consider trying to convince my friends to stop using Signal so much and start using Berty more lol. Very hopeful about this app!

Just sent my first messages and it works perfectly! Such a cool piece of technology! And what a design! Even the off-grid Bluetooth channel works! Quite impressive for the first version of such a challenging app.

What's new

- Fix a bug preventing a contact request from being sent/received after switching the app to background
- Fix performance issues

This is a test version for people who want to experiment with Berty. Be careful not to use it to communicate sensitive data.
