Telegram & Discord Bot Hosting Help

I already have the foundations of two Python-based bots—one for Telegram and one for Discord—built for customer-support conversations. Some modules (commands, reply handlers, and basic APIs) are finished, but other pieces still need coding, testing, and, most importantly, stable 24/7 hosting...
