Build with docker

# building image
docker build -t simplebot .

In container bash you can do same bot running as in quick start section

Quick Start: Running a bot+plugins

(Replace variables $ADDR and $PASSWORD with the email and password for the account the bot will use)

  1. Add an account to the bot:

    simplebot init "$ADDR" "$PASSWORD"
  2. Install some plugins:

    pip install simplebot-echo
  3. Start the bot:

    simplebot serve


SimpleBot is a base bot that relies on plugins to add functionality.

Everyone can publish their own plugins, search in PyPI to discover cool SimpleBot plugins

⚠️ NOTE: Plugins installed as Python packages (for example with pip) are global to all accounts you register in the bot, to separate plugins per account you need to run each account in its own virtual environment.

Creating per account plugins

If you know how to code in Python, you can quickly create plugins and install them to tweak your bot.

Lets create an "echo bot", create a file named and write inside:

import simplebot

def echo(message, replies):
    """Echoes back received message."""

That is it! you have created a plugin that will transform simplebot in an "echo bot" that will echo back any text message you send to it. Now tell simplebot to register your plugin:

simplebot plugin --add ./

Now you can start the bot and write to it from Delta Chat app to see your new bot in action.

Check the examples folder to see some examples about how to create plugins.

Note for users

SimpleBot uses Autocrypt end-to-end encryption but note that the operator of the bot service can look into messages that are sent to it.


SimpleBot is based on deltabot
