Public 24/7 Deployment Guide

Why Not Render Free Tier?

Render free services automatically sleep after inactivity, causing Telegram bots to stop responding.

For a free always-on solution, PythonAnywhere is recommended.

Step 1: Add Restart Protection

Wrap your polling logic in a restart loop:

import time
import logging

logging.basicConfig(
    format='%(asctime)s - %(name)s - %(levelname)s - %(message)s',
    level=logging.INFO
)

def main():
    while True:
        try:
            print('LifeBrain Bot is starting...')
        except Exception as e:
            logging.error(f'Bot crashed with error: {e}. Restarting in 15 seconds...')
            time.sleep(15)

if __name__ == '__main__':
    main()

Step 2: Deploy on PythonAnywhere

git clone https://github.com/ramkumar27072006/LifeBrain-tele-bot.git
cd LifeBrain-tele-bot
pip install --user python-telegram-bot

Step 3: Run in Background

nohup python main.py &

Check running processes:

ps ux

View logs:

cat nohup.out

Step 4: Share Your Bot

https://t.me/YourBotUsername

Notes & Limitations
