End-to-end Encrypted Facebook Messenger

Version License

Zuccnet is a fork of https://github.com/mjkaufer/messer, a command-line client for Facebook Messenger. Only difference is, Facebook can't read your messages.

It is known that Facebook scans your messages. If you need to keep using Facebook messenger but care about privacy, Zuccnet might help.

It's pretty simple: you and your friend have Zuccnet installed. Your friend gives you their Zuccnet public key. Then, when you send a message to your friend on Zuccnet, your message is encrypted on your machine before it is sent across Facebook to your friend. Then, your friend's Zuccnet decrypts the message. Facebook never sees the content of your message.

I'm not a security person and there's probably some stuff I've missed - any contributions are very welcome! This is very beta, don't take it too seriously.

Quick Start

node version 12.x required

  1. Install zuccnet

    $ npm install -g zuccnet
  2. Run zuccnet

    $ zuccnet
  3. Enter your login details (your username and password are not stored)

  4. Get your friend's public key, and assign it to them in Zuccnet

    $ public_key "John Smith" /Users/tomquirk/Downloads/johns_id_rsa.pub
  5. Send them a message

    $ message "John Smith" Hey John, this is a super secret message
  6. 🪄


Do you store any of my data?

We don't store your username, password, or any of your interactions on Zuccnet.

The only thing we store is a temporary login token when you first log in. This let's us authenticate you with Facebook without you having to enter your username and password every time. If you want to get rid of it, simply run zuccnet cleanup, or if you're in a Zuccnet session, run the logout command.

Can I use a deactivated Facebook account?

No, unforunately not. If you use Zuccnet with a deactivated Facebook account, your account will be reactivated.

How do group chats work?

Messages from group chats appear like

(My cool friends) John Smith - hey guys!!$$@@

Send a message to a group by using the message command. The name is the name of the group chat! Reply works as normal

Commands Reference


Sends a message to a given user

(message | m) "<user>" <message>


  • message "Matthew" hello world!
  • m "Matthew" hello world!

When sending a message, Zuccnet picks the closest match to what you type in as user. For this reason, you should probably use last names if you want to avoid accidentally texting someone.


Replys to the last message you recevied i.e. Sends a message to the user of the most recently received message.

(reply | r) <message>


  • r "hey yo this is my reply"

Note: this will only work if you have received at least one message through Zuccnet.


Lists all of your Facebook friends



Displays the last n messages in the conversation with a given user. The number of messages to retrieve are optional (default is 5).

(history | h) "<user>" [<n>]


  • history "Matthew" 10
  • h "Matthew"


Displays the n most recent conversations. The number of threads is optional (default is 5). The --history option will display the 5 most recent messages in each thread.

recent [<n>] [--history]


  • recent
  • recent 10
  • recent --history


Clears the number of unread messages in the window title. Since we cannot listen on focus events, it has to be done manually.

(clear | c)


Logs you out



Mutes a thread. If no seconds are specified, the thread is muted indefinetely.

mute "<thread-name>" [seconds]


Unmutes a thread

unmute "<thread-name>"

Secret Mode

When in this mode, any messages sent or recieved in the thread will be deleted for you (note, they won't be deleted for everyone).

lock "Tom Q" --secret

Non-interactive Mode

Zuccnet can be run in non-interactive mode with command line arguments to execute a single command.

zuccnet --command='<command>'

Login will be prompted if this is the first time logging in.


  • zuccnet --command='m "John Smith" Hey, John'
  • zuccnet --command='r Hey, John'


If ever you want to clean up any old Zuccnet sessions and start from scratch, run:

$ zuccnet cleanup
